noMad | introduction
‘noMad’, a design proposal on behavioural based assembly, was developed at the Architectural Association School of Architecture’s Design Research Laboratory,a 16-month post-professional design programme. AADRL Design Research Lab | Organised as an open-source design studio dedicated to a systematic exploration of new design tools, systems and discourses, targeting design innovations in architecture and urbanism, the AADRL actively investigates and develops design skills with which to capture, control and shape a continuous flow of information across the distributed electronic networks of today’s rapidly-evolving digital design disciplines. Pursued by self-organised design teams, the studio is collectively addressing an overall design research agenda - ‘Behavioural Complexity’ through shared information- based diagrams, data, models and scripts.
Behavioural Complexity V.1 | Behavioural Complexity will investigate architecture as an instrument engaging both material and social forms of interaction. Social scenarios will be coupled with material life-cycles as a way of speculating on how we live and the role architecture can play. Behavioural, parametric and generative methodologies of computational design are coupled with physical computing and analogue experiments to create dynamic and reflexive feedback processes. New forms of spatial organisation are explored that are neither type- nor site-dependent, but instead evolve as ecologies and environments seeking adaptive and hyper-specific features. This performance-driven approach seeks to develop novel design proposals concerned with the everyday. The iterative methodologies focus on investigations of spatial, structural and material organisation, engaging in contemporary discourses of architecture and urbanism.

agenda | development of a self-assembling fabrication system utilizing machinic behaviour and real-time decision making to enable architecture with a sensory system. noMad proposes a behavioural fabrication system that marks a shift of our build environment as a finite lifecycle construct, but is instead looking for autonomous, non-finite and real-time solutions to adapt dynamically to the demands of its environment - constantly restructuring itself. In a self-assembling fabrication approach of ‚negotiated space‘, noMad aims to enable architecture with a sensory system, localising decision making by self-aware unit to unit communication instead of a deterministic, superimposed building plan. Anchored in the world of self-structuring polyhedra, noMad is based on principles of synergetics, the study of geometry in transformation and the impact of a local change on its global systems behaviour: a single unit can autonomously change state, shifting its state by a simple rotational translation from one polyhedra to the other. Hereby, noMad is operating on different scales of (collective) intelligence and behaviour, each autonomously self-assembling to the next higher order of organisation - from a highly mobile, nomadic states to high population spatial configurations. noMad proposes a system, that can self-regulate and adapt, react to outside influences and demands and encourages both interaction and communication.

building lifecycle status quo
The new temples are already cracked Nothing but future ruins material for the next layer. - Blixa Bargeld ‘Collapsing New Buildings�
The current state of the production of our build environment is defined by its building lifecycle and finite use of labour and material in its production. In both energy and time intensive process, fabrication and construction is exclusevely coming into force for one sole, pre-defined purpose - and consequently its product demolished if either no longer in need or if its purpose merely adjusted or in need to adapt to changing dynamics or requirements. In stark contrast to the name-giving lifecycle of a living creature - unpredictable and highly adaptive - our notion of a building lifecycles is restrained as a static construct of limitations and predeterminations.

01_ non finite
The current state of the production of our build environment is defined by its building lifecycle and finite use of labour and material in its production. In both energy and time intensive process, fabrication and construction is exclusevely coming into force for one sole, pre-defined purpose - and consequently its product demolished if either no longer in need. In stark contrast to the name-giving lifecycle of a living creature - unpredictable and highly adaptive - our notion of a building lifecycles is restrained as a static construct of limitations and predeterminations. noMad - as a system more consonant to its biological role model - is non-finite in application, way of usage and site alocation, replacing the notion of building as a static construct that remans unchanged until its fundamental demolishment. Able to disintegrate when no longer needed, a non-finite system is can break down again to its simplest component or migrate to other building sites where, without material consumption, adjusting and adapting to changing dynamics or requirements in its environment.

02_ mobility
To react intelligently to the demands of urban development and the transport network on all scales in the course of growing interconnectivity, noMad’s research focused on mobility through locomotion, material reduction, flexible configurability and an extensive integration of the interface of mobility and the build environment as the convergent evolution of the static concept of architecture. Conventional usage of liveless, static building materia depends on being externally placed to its destined location - to remain there, brick on brick, until it is manually removed again. As low performance infrastructure is becoming a major limiting factor of rapidly growing megacities, noMad is bringing together the resource saving benefits of independent locomotion infrastructure with the amenities of non-finite building. Designed as a mobile, nomadic system, noMad can autonomously transport itself to building site by means of locomotion.

03_self assembly
Originating in the study of complex systems, the concept of self-assembly is an emergent process where pre-existing components of a disordered system find order and structure. Trough local interactions between its parts, a system can build an ordered structure that can be either static or dynamic. The idea of self-assembly - applied in architecture - can be a logical approach for a more responsive architecture, implying more comprehension on material behaviour, reconfigurability of spaces and a more intelligent system deployment. A self-assembling fabrication system is overcoming the dependency on man or machine force needed for its construction cycle. Machinic and robotic assembly instruments are not used as external devices, but are integral part of the building components themselves. Therefore, noMad’s space building capabilities are inherent in its units body design, allowing it to relocate, assemble and (de-)construct to reach a higher order of organization and complexity.

04_ self structure
noMad’s self-structuring qualities are inherent its geometrical properties. Due do its polyhedral structure, there is no necessity for external system of trusse, scaffolding or support material. Aiming to use the smallest self-structuring determinator, most explorations in self-structuring systems are anchored in the world of polyhedra. When talking about framing of space, the cube defends its undeserved fundamental significance as our main geometrical point of reference. Never having been subjected to experimental verification, the cubic plane of references still define our spatial understanding of up to today. It has been only in the last 50 years that polyhedra have been acknowledged as structural objects. A cubic frame would always be unstable due to its six degrees of freedom and collapse, stabiliziation requires e.g. the joining of the vertices by six additional struts. The tetrahedra described by these diagonals alone could arguably be seen as the more direct initial for a minimum rigid three-dimensional frame

05_ self awareness
The idea of “self” in systemic thinking specifies any type of system that has capability of finding order of a higher hierarchy through local interactions between parts. It should be one that reacts to inputs, translating it into outputs based in the internal logics of the system. It’s through the observation of specific parts that one can understand the larger system. To enable architecture with a sensory system, each building block requires a certain degree of self-awareness. With each component being aware of the state its in, the state of its surrounding and able to communicate this with neighboring units , independent solution finding is made possible for the system. This self-awareness is reached through simple computational means of “states” on a voxel based grid, i.e. clearly defined neighborhood relationships (i.e. location on grid, kind of allowed neighborhood density etc) and clearly defined range of states (i.e. degree of transformation, open or closed components, available as potential input etc.). If a building block is not given a sense of “identity”, it is incapable of independent decision making or intelligence.

06_ space negotiation
Corresponding to its self-dependent rules of awareness, assembly and structuring, noMad follows a fabrication approach of negotiated space. In a neither solely bottom up nor top down strategy, the system (re-)acts goal oriented. As a self-organizing system, it is not following a deterministic, superimposed masterplan. Localized interaction and decision making is enabled through unit to unit communication, negotiationg each individuals aims of mobility and space-making in a resulting higher order of swarm behaviour. Formations can therefore reach an ordered state of temporal equilibrium, performing differently than its isolated components, but always shift back to dynamic decentralization of local interactions, re-configures a system triggered by random fluctuations

scales of operation |
single unit |
Through the use of active and passive geometry shifting components the system can reconfiguring its global behaviour. Based on self-structuring qualities of polyhedra, the research is engaging the issues of mobility, self-structuring and space-making. When applied, noMad’s system of assembly operates on three distinct scales of intelligence and autonomy. Each scale is autonomously self-organizing and self-assembling to reach its next higher order of organization.
Beginning from its smallest operational scale, the single unit, the system is still capable of simplest decisions and actions, such as changing the state of the unit, limited locomotion, connecting and disconnecting from an global system. The unit is the main building block, based on a simple rotational movement of the faces of an octahedron around the vertices of its neighbor. Within this transformation, the unit starts from octahedral state, expands to an icosahedron, cuboctahedron, back to icosahedron an and octahedron again. Central design features focus on the activation of the single unit through internal controls and mechanics, possibilities of the single unit to self-connect and disconnect to system, mobility through locomotion, soft faces and control over its internal equilibrium.

nomadic body |
high population collective |
The formation of nomadic bodyplans - both through detrministic and stochastic means - is where the intelligence of the system starts. A logic of potential shape grammar combinations is defines the body like a genetic sequence: The ecology of machines shows creature-like characteristics and highly specific behaviour both due to their individual bodyplans, i.e. the physical body, and its sequence of activation, i.e. choreography of movement. The choreographies enable features and abilites such as lifting matter, walking or snake-like locomotion, rotational or translating arms and cranes etc. Only a few of used components having active capacities while the rest of the structure reacts passively.
In the scenario of high population settlements, parts of the system lock in, losing their highly mobile features in favor of spatial and structural configurations. Transformation is now used for optimization & adaptation through reconfiguration, i.e. temporary scaffolds during its own build-up process, lifting up of extensions and outer parts of the structur, or temporarilty repositioning to allow another body to get in place. Testing different deployment strategies and time based form finding through motion, fabrication driver of higher organisations is the catalogued behaviour of nomadic bodies - meaning every larger superstructure accumulation is defined by its multiple bodies coming together.

architecture that demands mobility | Architecture is exposed to change. Change may occur in site conditions (triggered by change in atmosphere and/or nature) or in programmatic demands (developing social dynamics). Change demands flexibility, flexibility demands mobility. In the city of of London, one in five of its population, meaning over 800 000 people, are commuting daily, raising by 10% in 10 years. Millions of people rely on the capability of transportation systems each day. Especially with todays complex growth of megacities, new city regions sprawl far beyond usual boundaries of one single city - the effectiveness of infrastructure lagging behind populations needs. Mobilty low performance infrastructure is becoming the limiting factor of rapidly growing megacities. This concept of urban temporality and its higher then ever reliance on mobility is solely shifted onto the individual’s mobility, ‘Urban nomad’ is long synonymous for today’s city population. The city surrounding the human remains as a static construct with little ability to adapt to chaging needs. Our current approach to architecture and urban development results in delayed reactions with no possibilty to respond in real-time, demanding long procedures of manual planning and concessions. Todays society’s demands not only ‘urban nomads’ but ‘nomadic urbanism’.

architecture that demands autonomy | The need for autonomy, i.e. non-human reliance, in architecture is primarily given by site-specific constraints - especially in the beginning and end of a bulding lifecycle, i.e. the process of fabrication and dismantlement. Aggravated conditions of construction in scenarios of extreme environments - that are either hazardous or difficult to reach for human labour - require either means of pre-fabrication and specific transportation to site or strategies of non-human on-site assembly. “Extreme� hereby can imply physical obstacles - of permanent (like extreme heat or cold, extreme heights or depths) or temporary (post-disaster scenarios, like earthquakes or flooding) nature. Besides site-speficic constraints, programmatic conditions like non-human inhabitable spaces, research or space stations Architecture enabling either autonomous fabrication or maintenance is being beneficially applied in fields of high density and utilization, i.e. in todays megacities, where machinic and automated decision making and ability of self-repair has become potentially more efficient then manual labour.

Machinic Behaviour | noMad’s research is concerned with the system’s machinic behaviour, including aspects of fabrication and simulation of material and physical behaviour of our system. Due to its space-packing, self-structuring and kinetic requirements, the system is grounded in the world of polyhedra and synergetics, the study of systems in transformation. The research deals with geometrical explorations, especially transformational geometry, their spatial configuration, reconfiguration and locomotion and the common aim of making. The central focus of making aims to develop demonstratable prototypes within a streamlined process of fabrication. The physical design-proposal of a unit is tested with various approaches of embedded mechanics and constructions in order to activate and realiably control the systems movement. Digital simulations of global system behaviour resp. impact of local transformation on physical and mechanical behaviour are developed to catalogue emergent phenoma, both under space-making and structural - ‘static’ criteria as well as ‘dynamic’ properties, i.e. reconfigurability, flexibility and mobility.

Communication based Behaviour | In order to define the system’s internal motivation or performative criteria, particular problem-solving, goal oriented simulations are developed, emulating behavioural and communicational aspects of the system. A computational abstraction model of physical geometry is utilized to emulate the behavioural and communicational aspects of the system. In these automated, goal oriented movement sequences, the communication between multiple bodies is driver for decision making. These simulations are driven by individual scenarios and situational responses. Bevavioural based simulations are conducted within a minimal framework of constraints like its reference to the groundplane. In course of the experiments, the system creates a self-imposed context to react to (such as maximum number of possibly arrayed passives without active unit or self-interlocking) to achieve a specific goal (finding another, reaching or avoiding an area of poential settlement, building up etc), As we are proposing to create a system that can self-regulate and adapt, but is not closed in itself but can also react to outside influences and demands, the research seeks to define both internal and external stimuli, encouraging both interaction and communication.

Geometrical Exploration & Transformation | Grounded in the world of polyhedra and transformational geometry, the research engages with their specific space-packing, self-structuring and kinetic properties. Based on the theory of synergetics, the study of systems in transformation, the system seeks to explore the relation between platonic solids and fosters their highly specific geometrical attributes.
Spatial Configuration | Through the development of different computational models, the system’s space making abilities were tested and evaluated by means of different growth and branching logic of spatial collectives. The tests follow specific, simple goals - i.e. a bridge, a vault, a pillar, - or properties i.e. porosity, stability, efficiency - to perform compression based aggregations due to the component based nature of the system.
Reconfiguration & Locomotion | When studied in a collective scenario, the system’stransformational and geometrical specifics show emergent behaviour, enabling the system to create flexible, adaptive spaces and re-position itself by means of locomotion. Both a taxonomoy of creature-like bodyplans with specific mechanical behaviour as well as the assembly process of larger settlements is developed.

artificial intelligence | self-awareness intro | self-learning Self learning started to be one of the most desirable achievements since cybernetics and robotics were founded. At the same time rapid development of self-assembly field (in particular modular robotics, which is self-reconfigurable, self-replicating or even self-repairing) provides us with both conceptual and technical opportunity to create intelligent and atomic/modular system adaptive to the human and responsive to changing environment: complex cohesive systems consist of same simple units with short range of trivial rulesets. Gordon Pask SAKI (Self-Adaptive Keyboard instructor) machine was an instance of machine-to- human and back interaction and double-beneficial process of learning, on one hand person was able to learn from machine preprogrammed response, and on the other hand machine could learn with a certain degree of precision from the human behavior reaching as follows the loop of self- learning. Thus self-learning seems to be the crucial part of self-assembly as bilateral process of interaction between people and the system. We are more interested in machine learning, nevertheless we can assume not only robotic learning from users and surrounding context, but also people’s ability to change their scenario and build new neural connections according to system behavior. For instance person is trying to avoid boring permanent view from the window (and he or she doesn’t know exact states of the system and doesn’t have yet such kind of spacial interior) and input this command into systems (modular habitation in this case). Then machine makes decisions related to input and develops a strategy based on self-learning algorithm improving result from time to time. On the other hand person/user gets new information about possible desirable positions (if not occupied by neighbours) and also learns to define new more sophisticated input next time.
early implementations | learning algorithms Self learning started to be one of the most desirable achievements since cybernetics and robotics were founded. At the same time rapid development of self-assembly field (in particular modular robotics, which is self-reconfigurable, self-replicating or even self-repairing) provides us with both conceptual and technical opportunity to create intelligent and atomic/modular system adaptive to the human and responsive to changing environment: complex cohesive systems consist of same simple units with short range of trivial rulesets. William Grey Walter’s Tortoises (first two named Elsie and Elmer) was probably the first instance of self-aware machines (as a logical result of his brain studies) being able to correspond to the environment switching between several task performance: wandering pattern, locking into a light, oscillating after encountering the obstacle and mirror dance (self-recognition including mating dance of two robots at the same time). The Interpretation of tortoise as a nonorganic living includes motor parts - wheels, forks, engines and battery; perception organs - photocell sensor and contact switcher; and finally the brain that consists of 2 neurons wires between motor and sense units.! Unlike Wiener’s military oriented cybernetics Walter’s experiments were more amateur and science directed. Goal seeking and scanning together became to main concept of creation Nevertheless William Grey Walter was fully aware of tortoise’s possible military applications by using two photocells and transforming robot into self-directed missile. John Johnson also assumes the usage of tortoise’s photocell as a guiding fro the gun or robot itself as a carriage of the explosive being detonated contacting the obstacle. Anyway Walter always had an attitude to his invention and exhibited it as a model brain. Apparently we find it quite useful in terms of present paper’s topics as a first robotic intelligence that inspired scientist of next decades.

self-awareness
Since that time humanity advanced much further towards artificial intelligence in terms of neural networks creation, complex adaptive systems with weighted connections. Contemporary scientific concepts use the apprehen sion of brain structure and actioning divides generally into supervised (providing of sample of answers or ‚teaching’ the system), unsupervised (clustering of information into unknown pattern) and reinforced (making decision based on previous outcome and adjusting the weights of network) branches of learning principle. Early Grey Walter’s experiments (inability just to sum neurons to achieve brain) and modern neural network algorithms opened a way for us to integrate intelligence in self-assembly systems. Given approach allows self-reconfigurable systems to define adaptive strategies along the process of adaptation and interaction with outer and inner world.
self-learning | contemporary robotics Nevertheless, what if we don’t want to define predetermined rules of movement? Zykov, Bongar and Lipson developed computational and physical models of robotic introspection (so called self- modeling) which involved 16 basic self-directed interactions with the environment. Researchers simulated situation of interconnection between curiosity and cognition in animals and humans for creating new kind of behaviour through the robotic introspection. Locomotion is achieved without any internal model at all only due to the learning process. Utilizing described approaches we have freedom to create total learning from the process of local behaviour to the global strategy. Without any movement algorithm machine starts to acquire skills of locomotion through the series of trials and failures which can be integrated into our strategy of self-assembly by architects and engineers by enduring modular structures with the ability of introspective learning or mixing it with more predefined motion algorithms (it doesn’t mean that deployment tactics should be predetermined as well, by the reason that they are two different learnings - motion ability and path/place finding optimization). Jason Yosinski and team created 4-legged robot that reminds unusual qudruped spider. As they suggested that translation from digital simulation to physical environment wouldn’t be so accurate and smooth, they started immediately from second one. Robot was able to improve basic hand-coded walking ability. Implementation was totally based on gait-learning algorithms of two major classes: locally searching models (based on parameterized motion) and evolving artificial neural networks (using platform of HyperNEAT generative encoding).! To be more precise, scientists explored 6 various parametric learning methods: uniform and Gaussian random hill climbing, policy gradient reinforcement learning (gradient descent), Nelder- Mead simplex, a random baseline, and a new method that builds a model of the fitness landscape with linear regression to guide further exploration. It was obvious from tests that all the variants were more successful than manually-designed walking strategy, however solely the linear regression and Nelder-Mead simplex algorithms outperformed a random base-line. Moreover, HyperNEAT provided the best result, 9 times faster physical motion than hand-coded behavior giving complex coherent motion patterns with multiple but coordinated leg movement frequencies. Although Paskian Universal constructor manifested self-replicating automata that was reconfigurating avoiding obstacle. It seems to be reasonable to continue with modern results in modular robotics. According to Hod Lipson, self-replication is observed in natural self-adaptive ‘machines’ such as crystals, waves and automata, the same principle became the basis of Molecubes. Approach of units reconfigurations of a cells of a building or modules as a building in the city that can be considered as megastructures. Structure combines computational simplification of the lattice/grid system and spacial ability of chain one. If we assume that the habitation is inside the giant molecube (test sample was only 10 cm edge) we should invent the technique to stabilize the horizontal ‘floor’ plane inside the transformable unit (interior of half of the cube). Moreover, even if we will decide to apply the Machine Metabolism principle of Cornell Creative Machine Lab’s team on self reconfiguration within cubic grid, we still need to deal with r!esulting rotation and horizontality problem in inner body of each particular moving building block.
page 47
brief research | artificial intelligence
Obviously we have few possibilities to implement this transformation desire. One of them is to have equivalent spacial organization on each face (we are more interested in internal ones while external can be produced as a monoshell structure) of geometrical unit. Thus we will be able to use ceiling as a floor etc. (more suitable for public architecture, spaces with small amount of internal elements). The opposite example of habitation requires to introduce either internal shell rotating in the contrary direction to main movement or local compensatory mechanisms that translate and orient details of the interior according to the changing spacial orientation. And finally, method, in which all the internal filling (furniture, equipment, etc.) should be just fixed strongly enough and final state of every unit’s translation remains the same as initial with regard to horizontality and gravity. In first and second case we are able to assume the tools allowing person be inside during the whole project of self-reconfiguring locomotion process of the megastructure. However even the last option gives this ability if we implement small spherical compensating capsule for individual(s) or non gravity condition (decision should be made according to less resource consuming value) inside each module.
how predetermined it should be ? | softness Deterministic and stochastic reconfigurations are two ways to quickly aggregate large population of units. Latter means probabilistic and brownian-motion-like deployment of the system. Former, deterministic, is a strategy when modules are directly placed at the certain location (molecube example). Stochastic method is processed through ambient environmental energy for the transportation. Stochastic fluid environment could be simulated within the principle of fluid dynamics not requiring local force or locomotion skill as a passive self-organization ability. Technique is related to random arrival of new building blocks to the structure and provides ability to transform/morph into one of states of so called programmable matter where each living cell is programmed to serve certain mission within organism as in fluid environment. S!tochastic self-assembly was even proposed to serve rapid prototyping tasks at home. Hod Lipson and his colleagues compare self-reconfiguring robotics with metabolism process in living organism as a process of breaking down nutritions and creating new ones. It is also proposed by the Creative Machines Lab to reuse and recycle the modular elements as self-reparation of the structure (i.e. space stations, cell phone towers, skyscrapers) or exchange between different aggregations. Obviously we can easily expand this list to other typologies such including residential, commercial building and adaptive parts of museums or arenas. The usage could be extremely wide: from space expeditions (where we cannot afford to transport large variety of completely different units) to recovery not only from wear and tear, but from natural disasters like earthquakes changing only damaged modules and leaving the rest of survived construction. The system’s developing throughout a living cycle may be defined by implementing the genetic algorithm (planning path based on design constrains) as an alternative strategy to neural networks.! By doing mentioned steps we create kinematic structures allowing the 4th dimension to come to t!he architecture. Another possible direction of modular robotics and self-assembly notion is to introduce a soft module, a primary building block as in Cornell’s soft modular robot research which speculates on cubics’s modules flexibility attained by twist actuating cables between vertices of the cube; or authors’s AA research of term2 based on Fuller invention with transformable octahedron (into icosahedron, cuboctahedron and back to the initial state). In both examples we are dealing with 2 base states of geometrical unit - solid sustained (cube and octahedron respectively) and soft compliant (all the intermediate states of transformation). Despite of the fact that this technique brings additional flexibility and spacial organization with itself, it provides higher order of complexity formation). Despite of the fact that this technique brings additional flexibility and spacial organization with itself, it provides higher order of complexity that lies outside the main frame of the paper challenging more complex algorithms and c!omputation of behavioural logics.

peaceful competition | game theory Game of theory is a crucial inherent part of self-learning processes in machines’ environment. It helps to achieve best possible results in certain branching situations using computer-based modeling. Forcasting provides us to have assumptions and expectations and adapt artificial intelligence behavior to constantly changing context. One of the most significant founders of game theory are Von Neumann and Morgenstern. The discipline sourced from probability theory and mathematical statistics. The most advanced concepts of predictions in games theory are related to conditions with predetermined state space (example - chess). The notions of root, tree of moves and leafs - the outcome from ending states. This tree structure allows us to develop a strategy designing functions even in multiplayer games, where several systems are aiming to “win” (read achieve best possible solution or outcome) simultaneously. However we and our program implementations should be quite selective in trees using effective reduction introducing clusters of similar states. Emergence in contemporary game theory made possible opponents to adapt to each other showing learning behavior during the process of “playing”. Humanity has ability to use existing approaches of game theory smartly making short forecasts based on recent data taking into consideration the level of detail that can avoid butterfly effect’s inaccuracies. Synchronizing urban pattern with self-assembly we are able to assure duplex mutation based on artificial intelligence and Earth’s resettlement network, totally emergent in its essence. Machines for living and work can serve the idea of global adaptation and follow the people migrations (for instance escaping from the ‘dead’ city of Detroit after collapse of car industry) reusing the same buildings and travailing with owners avoiding problems of new property searching and its equipment. Acting this way we propose individual mobility in terms of houses (at least for middle distances within certain country if legislation restrictions will be not flexible enough). This strategy can can also provide a behaviour of machines that shifts human decision interfering into it and helping human to optimize trip and settlement solution by combining robotic self-learning and human brain into productive interaction. Game of theory gives great opportunity to play adults game within a big scale of suburban megastructures and within them between each particular unit. Systems are able to compete in terms of demand on resources or more solar energy efficient location. Nonetheless if the first one achieved the optimal configuration and position, second or others (in multiplayer game) exclude its state from the search path and continue new peaceful competition.

mobility in architecture | “The city of Sophronia is made up of two half-cities. In one there is the great roller coaster with its steep humps, the carousel with its chain spokes, the Ferris wheel of spinning cages, the death-ride with crouching motorcyclists, the big top with the clump of trapezes hanging in the middle. The other half-city is of stone and marble and cement, with the bank, the factories, the palaces, the slaughterhouse, the school, and all the rest. One of the half-cities is permanent, the other is temporary, and when the period of its sojourn is over, they uproot it, dismantle it, and take it off, transplanting it to the vacant lots of another half-city. And so every year the day comes when the workmen remove the marble pediments, lower the stone walls, the cement pylons, take down the Ministry, the monument, the docks, the petroleum refinery, the hospital, load them on trailers, to follow from stand to stand their annual itinerary. Here remains the half-Sophronia of the shooting-galleries and the carousels, the shout suspended from the cart of the headlong roller coaster, and it begins to count the months, the days it must wait before the caravan returns and a complete life can begin again. ” [ITALO CALVINO, The Invisible Cities (16)] In his book, “The Invisible Cities”, Italo Calvino presents several cities built under different aspects, describing them as unique landscapes and built spaces due to their inhabitants, as if they were singular dimensions that could also fit into the description of any city nowadays. When one begins to read the description of Sophronia, one of the cities of Calvino, instinctively think that the interim city is the amusement park. However, he twists this concept, suggesting that transient city is actually the one we know as permanent, the city of everyday, of the routine, the experiences, the flows and the trades. Sophronia only exists while there is interaction between the various groups that compose it. The immutability of architecture that constitutes society as we know it is exposed, leading to questions about how the city and its flows is perceived and experienced. The archetypes, as he describes them, exist, but the man is in constant motion, both physical as ideological, influenced by the - ever increasing - flow of information, and the architecture barely follow these changes. It’s their inter relations that give life to the city, and demolition, as highlighted, is the process that allows the finiteness of it all, leading to a consequent transformation and transience of architecture. The man is in constant motion, but always backed by references able to identify him and specify him a source, an origin, like a “fixed address”. An individual is nothing without identity within society. The state, as the name implies, is static, unable to live a real mobility. This whole concept conditions the man and his creations. The architecture, because of that, produces static buildings – heavy and non-mobile structures. Thus, faced with this sociocultural configuration, it is understandable that our reality must be static, or society as a whole falls apart. Humans needs easily recognizable icons and symbols to establish connections and relationships with the space in which it lives in. This comes from the necessity of finding themselves inside a changing landscape in order to develop a unique personality. He therefore is characterized in a static being, despite being in constant movement. The psychological structure of the society life is based in the relation and recognition of the space, as well as in the cultural assimilation. In this sense, the ‘fixed address’ acts as a form of socio-economic inclusion and integration.

mobile architecture
In the new technological and information era, however, the individual may be recognized in other socio-spatial situations such as the internet, which allows a certain level of mobility followed by the presence of them in non-physical ambient, but virtual, where the existence could be understood as a spatial mobility of the individual. Thus, the idea of thinking about architecture as a system, dominating all the process, is essential for the mobility thinking in architecture. It’s not about creating a different physical structure, but creating a new reality, a new method of living, a new relationship between man and space, which, in turn, culminates in the process through it is developed, in this case a flexible and mobile structure. However, a mobile structure, by itself, is incapable of promoting the mobility concept. For such, it needs to be able to establish deeper connections with the individual in addition to its physical structure, altering the method of interaction and user perception with the surrounding space. The period where these issues emerged was very propitious. If in the past there wasn’t much freedom of creation and need for change, in the post-war era that reality changed, with new architectural proposals promoting the interference and interaction with the user. The post-war created a complex urban situation, unlike anything ever seen before. Until then, the architecture was being designed to serve man’s needs, but completely connected with the monumentality of the spaces in which it was inserted. The period was marked by a profound economic, social and political crisis, which led the architects born in the midst of that to new questions about the structural principles of urban development, establishing more complex patterns related to the need of man’s identity standards. The first architects to think about mobility in architecture as a desirable need, worked with precepts of space modularization and scientification of architecture, through projects that required high technology to be designed, giving birth to the critical thinking about the sedentary bias of urban space. Those ideas arises in the context of the post-war, from the modernism and industrial era, as a still fairly utopian movement that found in technique the best way to structure and situate these intentions. They introduced discussions about the urban space and mobile and adaptable architecture, as well as questions concerning the design methods that produced the static structures of the period. Buckminster Fuller, Nicholas Habraken, Frei Otto and Yona Friedman were the architects who went more deeply in to these discussions on their proposals, with light, modular, disassembled and flexible designs. They introduced questions that, along with the counter culture movements of the 60s, eventually encourage a new generation of architects to think mobility as a new way of seeing architecture, both as a means of communication or as art, and especially as a way to establish a dialogue with the population. The influence of the Situationist movement led to deeper questions about the impact of this supposed mobility on society, dealing with the mobile architecture as an “artistic-cultural manifesto”, thinking of the city as a leisure space, a living experience transformed into adventure. They also considered the use of high technology as a precondition for mobile projects, as well as a means to promote their ideals. Everything that was new, mass-produced, was incorporated in the designs, which mostly had a great visual, aesthetic and provocative appeal, influenced by the Pop Art and electronic media. This way of thinking is linked to the communicative and questioning works of Archigram, Cedric Price and also artists like Constant Nieuwenhuys, with his “Unitary Urbanism”. Currently, questions about the mobility of man and structures, as well as the mobility altering people’s lives still persist, but away from specific conditions, without consideration of the space in which it operates, but with the ability to settle anywhere, as an architecture able to adapt. The urban space starts to gain more relevance, being important the relationship of the body with the built environment, exhibiting this relationship that is established through unusual, ephemeral and mobile proposals. Artists such as Lucy Orta, Krzysztof Wodiscko and Joep Van Lieshout illustrate this marginal and provocative art, where man is the center of the relationship with the city.

The architecture is now seen as a tool of man to achieve wellness. It conditions and defines their way of life and their interactions. Should thus be capable of shaping up to the needs and desires of society, through an adaptable, changeable, free and then, therefore, mobile architecture.

Yona Friedman (1923) was the responsible for coining the term. ‘mobile architecture’, with his manifesto for the X International Congress of Modern Architecture in Dubrovnik, in 1956, “Manifeste de l’architecture mobile”, where he expressed the needs for a more adaptable architecture, capable of understand the constant mobility of life. For him, the crescent automation of the production would increase the amounth of free time, changing radically the society. For him, the inhabitants should be owner of a “mass”, that would change accordingly to the demands of life. One of his proposals, the “Spatial City”, was imagined to allow the reorganization of the publica and private space. The Project consists of a structural framework that could be occupied by volums. This framework would give the user freedom to occupy or leave the spaces as needed, by rearranging the volumes through the structural voids. These structures should be capable of being dismantled, moved and be alterable at any moment, and should also touch the ground in a minimal area. The framework would overlay the existing urban fabric and and could make use of it’s existing infra structure, acting in the space where the actual city couldn’t reach.

nicholas habraken | ‘support’and ‘infill’ Nicholas habraken (1928) was one of the first architects to formalize the design process and create a more ‘responsive’ architecture, that fits its user requirements, by allowing them to interveine in the design. He found in the modularization of the space a method of allowing a certain degree of freedom and variability in the process of projecting architectural buildings, creating a series of recombinatorial pieces of the constructive system. He proposed the idea of separating the ‘support’ structures of the buildings, that would coordinate all the infra-structure, from the ‘infill’, that would be everything else, from interior to exterior of a house system, and could have a great range of variability, allowing the participation of the inhabitants in the process of designing.

Instant City, 1969-70 | Peter Cook, Ron Herron e David Greene
The Archigram group based his productions in the incorporation of technology and mass culture as a way of expressing themselves and the premises of the modern architecture, illustrating the future of the consumer society. They had a high tech approach, with lighweight structures, exploring the world of inflatables, capsule houses, nomadic, and computational architecture, exploiting a vision of interminable resources. For them, the most importante wasn’t the technology per se, but the new relations that were established in society by the interaction with these technologies, and the incorporation of them in the daily life. Their proposals were utopic in a sense, but extremely connected with the economical and social situation through which the new technologies, transport systems, communication and information were affecting the world. The Walking City was a mobile robotic structure, that could autonomously navigate and connect to other ‘cities’ when needed, to form a massive metropolis and disperse when no longer the connections were necessary. The Instant City, a mobile technological event, would offer a series of information and cultural events that would be carried from city to city distant to the main metropolis, working as complement to the city structure, supplying and attracting new activities to the small city and connecting it to the main one.

He’s famous for using projections in buildings facades. In his Homeless Vehicle Project, he legitimated the problems of the marginal community without legitimating the problems of homelessness, by building these vehicles for the homeless people as a tool for surviving in the city. Those vehicles called the attention of people and also gave an importance to the homeless, as they become part of something that generally they are not, earning space in society.

brief research | self-structuring geometry
polyhedral space | Aiming to use the smallest self-structuring determinator, most explorations in self-structuring systems are anchored in the world of polyhedra. Few polyhedra can be found in the natural world, most of them have been creations of the mind. Nevertheless, they have formed what is an ongoing puzzle for humans - trying to understand them long before Pythagoras modern mathematics. Ancient artifacts as e.g. East African foot rings or the semiregular polyhedral pyramids of Egypt are considered attempts to understand and replicate logics of polyhedral geometries.1 Ancient Greeks first started to theorize about relationships between polyhedra, defined their five regular platonics (tetrahedron, octahedron, icosahedron, cube, dodecahedron) and from there on accepted them as symbols for all and everything.2 Euclid’s Elements first described their basic geometric principles, but it was not until Leonardo da Vinci’s illustrations for Pacioli’s De Devina Proportione almost two thousands years later that the first polyhedra were properly shown as a lattice structure and - at the same time - Albrecht Dürers ‘Underweysung der Messung’ in 1525 unreveiling their explicit relationships by unfolding.3 When talking about framing of space, the cube defends its undeserved fundamental significance as our main geometrical point of reference. Never having been subjected to experimental verification, the cube arguably owes its special position to being the simplest geometrical shape to draw on a piece of paper in ancient times without today’s understanding of mathematics and geometry. Up to today, the edges of the cube define our understanding of forward-backward / up-down / left-right, any imaginable spatial reference or orientation. When dance artist and theorist Rudolph von Laban preferred the icosahedron as a frame of reference for his ‘Space Harmony’ choregraphies - to pattern repeatable movement sequences of moving through a predefined Platonic Solid - he mostly struggled with the realization that most of his dancers were just too culturally pre-conditioned to the cubic edges as ultimate definition of space.4

It has been only in the last 50 years that polyhedra have been acknowledged as structural objects. A cubic frame would always be unstable due to its six degrees of freedom and collapse, stabiliziation requires e.g. the joining of the vertices by six additional struts. The tetrahedra described by these diagonals alone could arguably be seen as the more direct initial for a minimum rigid three-dimensional frame.5

brief research | self-structuring geometry
mobile space frames | The first experiments on space-frames and triangulated spaces as self-structuring polyhedral systems were produced in 1902 by the same person who invented modern communication and the telephone: Alexander Graham Bell. Understanding himself as an universal creative, he was an active participant in the rapid development of industrial fabrication around the turn of the century, seeing the huge potential of ongoing technical improvements of the production process. The approach to his inventions was not looking for problem-specific solutions, but in reverse the development of technical or mathematical principles and then looking on how to apply them in retrospect. In this manner, he became both the inventor of the tetrahedral truss and the concept of the space frame. His interest in self-structuring systems was not grounded in an architectural application but in nautical and aeronautical engineering:1 The early prototypes of his tetrahedral space-frames were applied to enormous kites. Base unit of his system is a latticed tetrahedron of 20cm edge length, with a minimum number of members to create a rigid frame and therefore optimal weight and lightness for flying objects. He prefabricated an array of these basis elements as prototypes to create clusters and agglomerations with emergent qualities.2 The resulting compositions of tetrahedral were tested in the wild, extensively catalogued, reconfigured and optimized and tested again for their structural and technical properties. As a result, Bell created an empirical study of flying behaviour, all based on the same basic component but with performances far from what could have been expected from an isolated tetrahedron. Bell developed several principles and rules of optimization by introducing a hierarchy of faces, partly covered with fabric, and by minimizing the weight of the overall structure by dismissing central, fully surrounded tetrahedra.3 The experience gained from his tetrahedral kite experiments has been later implemented into complete architectural building structures of larger scale - the first being a 28m high watch tower in Canada in 1907. Here, Bell did not follow up the implications of kinetics and mobility, the main evaluation in his earlier flying experiments. But a number of new principles - a hierarchy in edges, the three continuous border rods of each tower leg being thicker where expecting higher forces4 - strongly link his self-structuring explorations to his other iconic research: the telephone as a network of communication. Bell did not see his prefabricated tetrahedral units as an isolated component of six rods and four nodes but as part of a bigger network: the single unit indistinguishable from the total system, behaving as a flow of energy with paths of thicker diameter transporting higher amount of force between nodes.

brief research | synergetic formfinding principles of synergectis | Rejecting the cube for reasons of instability, Buckminster Fuller made advantage of a coordinate system based on tetrahedral-octahedral space filling.1 Using the tetrahedral base unit for his system as initial setup, its vertices being defined by four closest-packed spheres, he started a catalogue of relational proportional polyhedra and their respective higly specific systems of interconnections, transformations and dynamic properties. In his main manifesto, the study of ‘Synergetics’ in 1975, Fuller gives a comprehensive area of reference for transforming systems and their emergent behaviour, unpredictable by its single parts - including the human in his role as observer and participant - defined by himself as: “A system of mensuration employing 60-degree vectorial coordination comprehensive to both physics and chemistry ... explaining much that has not been previously illuminated ... following the cosmic logic of the structural mathematics strategies of nature, which employ the paired sets of the six angular degrees of freedom, frequencies... Synergetics discloses the excruciating awkwardness characterizing present-day mathematical treatment of the interrelationships of the independent scientific disciplines as originally occasioned by their mutual and separate lacks of awareness of the existence of a comprehensive, rational, coordinating system inherent in nature.2 Central ideas Fuller lies out are the rejection of the commonly used 90 degree coordinate system in favour of omnidirectional 60 degree coordinates. In favour of the standard XYZ coordinate system, he introduces the Isotropic-Vector-Matrix (IVM), based on the unit-vector-length edges of the tetrahedron.3 Alongside this space describing system lies a revision of our notion of ‘dimension’: height, width and depth are described as three distinct dimensions, each behaving independly. As a means to describe the relative size of a unit and to quantify the relation of time and shape, Fuller introduces the measuring unit ‘frequency’: “Size and time are synonymous. Frequency and size are the same phenomenon.”4 This notion of four-dimensionality adds the dimension of physicality (time, mass) to spatial properties. “Geometers and “schooled” people speak of length, breadth, and height as constituting a hierarchy of three independent dimensional states -- “one-dimensional,” “two-dimensional,” and “three-dimensional” -- which can be conjoined like building blocks. But length, breadth, and height simply do not exist independently of one another nor independently of all the inherent characteristics of all systems and of all systems’ inherent complex of interrelationships with Scenario Universe.... All conceptual consideration is inherently four-dimensional. Thus the primitive is a priori four-dimensional, always based on the four planes of reference of the tetrahedron. There can never be less than four primitive dimensions. Any one of the stars or point-to-able “points” is a system-ultratunable, tunable, or infratunable but inherently four-dimensional.5 All platonic polyhedral solids defined within that system are inherently informed by and contained within each other and therefore able to switch states.

icosahedron, cuboctahedron and finally flips inside-out and collapses in mirrored order. Special significance Fuller puts hereby in the doubling of edges while the grid collapses and expands between its geometrical states - comparable to a hierarchy of capacities in a network. These theses by Fuller are never seen as a replacement of traditional mathematics but an alternative point of view, an attempt to integrate geometry and philosophy into a shared framework defining both the physical and metaphysical world.6 Fuller had a rather holistic understanding of his concept, including a wide field of disciplines of the philosophical and scientific world, such as geometry, chemistry, psychology, biochemistry and economics. Despite inspiring ongoing followers in their research on related topics, most of his ideas never reached mainstream recognition in the academic world. Especially the blurred differentiation or explicit relational understanding of apparent seperates - such as the physical and the ideal world, the human, micro and universal scale, the observer and the observed - challenged more conventional ways of thinking both at the time of Fuller’s publications as well as today. In similiar fashion in that he saw the future of houses as apparatus for receiving and broadcasting, he referred to his structural systems as ‘nets’, primarily not systems of physical interconnection but as networks of energy and flow. As conventional planning of permanent settlements and neighbourhoods would be rendered obsolete in a hyper-mobile age, nomadic systems of endlessly circulating bodies instead of physical infrastructure would lead the way. Within a system like that, the ability to disconnect is considered of equal importance as to connect.7

brief research | self-assembly systems
brief research | self-assembly systems
self assembly systems | Self-assembly is a process where pre-existing components of a disordered system finds order and structure through local dynamic interactions between its parts. It’s an emergent behaviour that can be found in complex systems. Self-assembly and self- organizing systems can be a response for a more automated and more responsive architecture. In nature these concepts are the very base of the building system of things, and analysing how naturally it happens in nature can give clues on how to improve the architectural systems that we rely on. Self-assembly systems can be a logical approach for a more responsive architecture, with more comprehension on material behaviour, reconfigurability of spaces, and more intelligent system deployment. These systems are plentiful in nature, and include the formation of everything from snowflakes, to biological structures, to galaxies. Trough local interactions, disordered parts can build an ordered structure that can be either static or dynamic. In static self-assembly formations, when the system reaches it’s ordered state it founds equilibrium, reducing its amount of usable energy. It must have a higher order that performs differently than its isolated components. Dynamic self-assembly process can also be described as self-organized systems, where the ordered state arisen from local interactions configures a system triggered by random fluctuations that allows a variety of states, a nonequilibrium system. The system is composed by agents that may or may not define the laws through which the systems responds to, and its organization is either decentralized or distributed all over the components of the system. Another concept linked with the idea of self-assembly is self-replication, a type of behaviour in dynamic systems that allows the construction of a copy of the agent. It is present in biology, in cell division that replicates the DNA, as well as for biological virus and computer virus for example. Cellular Automata, for example, is a type of system that recreates the replicating logics of nature, demonstrating that the essential qualities of self-assembly/self-reproducing systems were possible in material and mechanical systems . It’s possible to observe these qualities being reproduced in contemporary robotics researches, like the “self-replicator” robot from Cornell University. The idea of “self” in systemic thinking specifies any type of system that has capability of through local interactions between parts find order of a higher hierarchy. It should be one that reacts to inputs, translating it into outputs based in the internal logics of the system. It’s through the observation of specific parts that one can understand the larger system.

morphogenesis | is the biological process that causes an organism to develop its shape. It is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation. The process controls the organized spatial distribution of cells during the embryonic development of an organism. morphogenesis can take place also in a mature organism, in cell culture or inside tumor cell masses. morphogenesis also describes the development of unicellular life forms that do not have an embryonic stage in their life cycle, or describes the evolution of a body structure within a taxonomic group Robots inpired by natural process can be classified in two types, as morphogenetic robots and epigenetic robots. The self-assembly robots of the core of our research can be classified as morphogenetic robots.

early japanese experiments with modular robotic [MR] systems where represented as a m-tran implementation. as ‘usual’ in MR it was used identical modules, but probably for the first time such a fertile veriety of configuration was achieved. thus robots were able to move as a snake, 2- or 4-legged creatures according to relief characteristics and stability issue. mentioned application approximates the discussed future of extraterestrial expeditions when we don’t need to send different expensive robots but only plenty of modules instead.

As the platonic solids of the regular octahedron, isocahedron and cuboctahedron are inheritently embedded within each other, they can flip stages from one to the other by a simple rotational movement between neighboring faces on its connecting vertix. the resulting geometry expands in volume and re-configures its face’s neigh- bourship relations, in a 5 staged loop.

soft faces | Given the ability to autonomously connect and disconnect to the system, the usage of soft faces allows simple movement by extending its faces and the ability for a unit to connect and communicate to close by neighbors. By retracting its faces, a system can disconnect already assembled units or dont allow a connection to begin with, i.e. in case of overload etc. This flexible center of the face allows two varying degree of freedom of connected units: a flexible, central connection that allows a rotational degree of movement or rigid face to face connections for structuring purposes. soft faces are tested through the use of soft materials and membranes, inflatables and through patterning.

unit actuation | By the means of Arduino/based micro-controlling, different mechanisms of activation were tested to automatize the unit, both to enable its control over its faces (to make small relocation and movements within the grid) and transformational mechanism.

study of emergent behaviour | a synergetic - i.e. actively transforming - unit has the capability to change not only its own state but when operating in a field re-configure its surrounding. in a butterfly effect of onpassing reactions, the local change of the active unit has a global impact on all passive units within the same system. in a series of physical and digital tests, overall system behaviour was tested to predict and control local and global changes of organization.

initial aggregation study
magnetic faces were created in order to facilitate the physical prototypes. The magnets allowed to create different aggregates quickly and analyze its impacts and its body configuration. the idea of having transformable units that could increase in size and aggregate to new ones in order to generate more complex behaviours opened up a new range of problems. The capability of aggregating had to be translated also to the simple units, and the metod of connection was yet to be explored. However, the idea of having magnectic faces that could be controlled later by turning on an off added a new degree of freedom to the system, as at this point, any unit could be capable of aggregting and creating new bodyplans. So an active unit could choose between it’s neighbours and collect them according to it’s objectives. in order to achieve it’s desired bodyplan configuration, perform complex tasks or simply to work locally as an interchange unit, the idea of realocating neighbours was a key point, creating clusters of local intelligence in the system. This capablity of realocating the passive units attached to an active body could save energy and help the system work more effectively, as any passive unit attached directly or in a chain to an active unit could be transported to new locations without having to be activated.
page 181
ecology of machines| unit aggregation
the relation of the active unit with a stable point and to its connected passive units affected it’s final configuration in the three states. Some aggregations could be explored in order to achieve specific objectives. By trying to make some bodyplans behave in specific ways or to move in a field in order to reach a target, a range of different creature-like bodies that were capable of behaving in specific manners were developed. two active units | endpoints: locomotion through active endpoints

two active units, when connected to a series of passives with fixed face to face connections had some limitations when acting as a single bodyplan. First, the activation of these units had to be coreographed, so one wouldn’t block the movement of the other. When activated alone, each unit was two active units | center: rotational movement around central axis

two active units, when directly connected, showed the ability of duplicating the size of the bodyplan, allowing the “arms” (the passive units connected to it) to achieve new positions in the field, that could two active units | endpoints: locomotion through active endpoints

legend
the studies show emerging behavior of multiple simple units combinations. different face to face relations and methods of arraying (linear | radial | helix | branching) have been tested and compared, leading to different qualities in degree of freedom, movement, relocation/locomotion, cantilever, stability. those studies were important in the awareness of how many and how the units should connect in order to achieve specific spatial movement. This research was the first step in the creation of an ecology of machines - specific bodyplans with different abilities and objectives.

ecology of machines | taxonomy
taxonomy | mechanical simulations the analogy with a ‘grammar’, where letters can form words, and words can be combined into varied phrases led to the creation of distinctive bodyplans with nomadic behaviour, that were later organized and catalogued in a taxonomy of families due to their individual body plans and sequence of activation this ‘ecology of machines’ opened a new world of exploration and possibilities, as each machine exhibit life-like behaviour, with different objectives and awareness, being capable of taking decisions and make the system interact and adapt, triggering emergent events and augmenting the intelligence of the system, only a few of the used components has active capacities while the rest of the structure reacts passively, saving energy and adding efficiency to the system
legend
some cataloguing of movements made clear the limits and capabilities of each machine, offering evidences of when and how to use each one. the taxonomy can be understood as a genetic sequence: a shape grammar of simple choreographies that can be read as features and abilities such as lifting matter, walking or snake-like locomotion, rotational or translating arms and cranes, etc.

behavioural simulations | in order to simulate a more automated, goal oriented movement sequence and communication between multiple bodies, a computational abstraction model was developed to emulate the same rotational movement around two simultaneous axis of the physical geometry. the emulation was the first step into the understanding of the emergent behaviour that could come out of the collective behaviour and interaction of multiple machines. the computational simulations were important to expose the limits and possibilities of the system and the defined families of creatures. through simple embedded intelligence - such as maximum number of possible arrayed passives without active unit, reference and sticking to the ground, no self and ground interlocking, etc. and simple goals - like find neighbours, reach or avoid and area – a body autonomously adjusts and optimizes its own movement sequence.

space making criteria
spatial configurations | Through the development of different computational models, central evaluation criteria of high population collectives are defined by the systemâ&#x20AC;&#x2122;s space making abilities. Spatial configurations were tested under specific, simple goals - i.e. a bridge, a vault, a pillar, - to perform compression based aggregations due to the component based nature of the system. The deployed system aggregates with an adaptive degree of detail, allowing a higher density grid where finer resolution is needed, i.e. for fine elements or strong surface curvature.

spatial configurations | The results of nomadic bodyplan research serve as base for the testing and evaluation of different growth and branching logic of spatial collectives. Results showed a varying degrees of enclosed space, porosity, stability, potential expansion, efficiency, spatial and aesthetic qualities due to different combinatorial rules and restraints. When we talk about higher organisations of collectives this catalogued behaviour is the driver of the fabrication, Meaning every larger superstructure accumulation is defined by what multiple bodies come together and how.

supergrid formation | Each nomadic â&#x20AC;&#x2DC;creatureâ&#x20AC;&#x2122;, according to its specific bodyplan and sequence of movement, creates its own specific grid, In the assembly process of collective settlements, i..e. semi-mobile superbodies, the structures and spaces a creature can fabricate are directly related to the its potential deployment locations, meaning the path it operates on. Therefore each individual bodyplan also results in a specific supergrid with distinct qualities - either coherent or hybrid through the symbiosis of multiple different nomadic bodies or the breaking down resp seperation of a nomadic body in its simplest parts.

Due to their limited freedom of mobility and little volumetric qualities, a combination of certain bodyplans can only create structures with high porosity and therefore result in strand-like, porous scaffolding systems. The example of a linear simple walker offers only limited active connections to branch at its ends (max 3 branches on one active unit) and can only operate on a limiting turning circle due to its simple sequence of movement. A wall sized structure (Cluster 1.3.) is build from ca 400 units with 1/3 of them acting as actives.

More complex nomadic bodies spot a high amount of possible vertical and horizontal connection-faces and allow dense branching around its active units (up to 8 possible branches). Versatile branching and growth logics can pack the space with less gaps, creating fully double curved surfaces.

The nonlinear origin of attractor is also used for creation of fluent interconnected body. After certain iterations constructionâ&#x20AC;&#x2122;s cells have ability to freeze as they become geometrically stable.

communication based simulation | In contrast to the mechanical / spatial approach of growth and granching logics, automated simulations of larger autonomous populations are based on the communicatioal aspects between units. The development of algorithmic rules of interaction and unit relations result in self-organizing crowd behaviour. A field of passive units, as “dead” material, is potentially shifted around in space by a connected active unit. Movement fundamentally starts on the ground plane or - if an active unit autonomously decides on a potential building site for a settlement start build vertically. These goal oriented simulations create negotiated space, i.e they act according to an dialogue between: • bottom up decision making of every single unit for example: if it is in the center of an overpopulated area, an active unit can decide to act as an repulsor, creatng void spaces or, if an active unit is in an empty area, it can act as an initial seed for a settlement as attractor to other units • top down rules such as: different deployment strategies, dependent on their initial istribution (i.e. multiple seeded building scenarios), migrateing from one site to another
