RobotCube This research focuses on examining the interaction between the machine and spatial perception. We are concerned about whether there are possibilities for a new correlation among the space, machine and image. This research combines the large-scale robotic arm with the interactive image, and give full play to the technological and art potential of dynamic projection to create the sensory experiencing combining the virtuality and the reality. This research is devoted to the field of spatial sensing and human-machine cooperation, and combines the generative art, robot interaction, and real-time 3D mapping. Meanwhile, this research adopts motion and automation as an innovational medium for further development. The works are created through improvisation, enabling the performer and audiences to coexist.

Medium X light This research is based on the premise of the 3D printing methodology, which incorporates the discussion of the immaterial (light) and the material (transparent Polylactic Acid). Through testing various parameters that enable light to contain inside the medium and also control the refraction of light and the path of the light. This research proposes a new method to revise light trajectories and reflection and also create a unique light atmosphere. Under process, model an adapter that holds the PLA plastic gun and mounts it to the flange of the robotic arm, operating different control variables such as density, layer height, printing path, and different light sources, to analyze light imaging under different conditions. Thus, integrate these conclusions to generate individual light performance. As for the main goal in the next stage,we not only want to create pattern or alphabet but a space or atmosphere which affects people’s emotion or vision in a more directly way.

these test parameters can be applied to architectural element fabrication process so that “a brick” can include special light effect.

In the final design, we enlarged the scale to a level that humans can perceive. On this basis, the parameters of these control variables can be further integrated to create a special lighting atmosphere. We include the movement of '"rotation" into the final design process. If the light source is projected in a fixed direction, we will find that during the rotation, the position of the projected light source will form a constantly changing curve, and will

between light and shadow. The value of this case is to extend the material to the discussion of spatial perception. At the same time, the operation method is based on the integration of materials, robot trajectory planning, and speed.

Tube In Construction In this research, we focus on the potential structural performance between metal bending and interlocking joint. We are interested in the high degree of freedom and continuity of metal bending. Proper use of composite materials can also give full play to the advantages of materials. Materials can be converted into different forms through processing. We explore whether the material geometrics can bring more possibilities for design through joints and forms. There is a connection between material geometrics and the structure. Based on Daniel Widrig’s interlocking structure research, we focus on the potential of it to apply to the metal bending assembly mechanism. Further, explore the mutual complementation of hybrid materials and implement it for the final fabrication. The advantage of the linear bending in the degree of freedom is very helpful to the integration process of composite materials. The iron can be bent into a U shape easily to meet the bottom-up design process. At the final stage, we focus on the performance between these two materials for on-site construction. We discover that the interlocking joint can help with positioning, and the elasticity of metal bending make timely adjustment onsite more possible.

Find out the geometry that matches the material characteristics to apply into design.

The value of metal bending: The joints and corners are usually connected via hinge joints, lap joints, welding, etc. The structural joints are usually unstable and become the vulnerable parts of the system. The traditional metal connection calls for the use of an arc machine to cut the round corner via welding or using screws to

The longer the overhang, the higher percentage of the damage to the metal tube.

In the early stage of the experiment, metal bending characteristics such as resilience and stress are tested. We use the self-made bending machine to bend iron bars. Through repeated combinations and connections of "a unit type", these combinations can form a complex structure. In the first phase of the test, we tried to use face-to-face connecting logic as our joint system for the metal tube, so that the components can be connected in multiple directions and shaped as a diverse outlook. However, the experimental results found that in the structural system, the metal pipes cannot be connected by the surface connection method. It must be thought of by the systematic joint method.

Mobile Plastering Robot In response to the digital era, the production model has been transformed from mass production to mass customization. In the era when the architectural manpower is lacking, we hope constructive robots can be introduced to the construction site so that the architecture industry can head towards intelligent construction. According to this, our team proposes a cutting-edge system that utilizes a constructive robot to finish wall plastering in space without any limitations. This research integrates materials, devices and robot plastering, ranging from the material testing, discharging of materials, and robot trajectory generation to the end effector design and machine vision. The process calls for a close collaboration of various parameters, and rigorous test of the discharging speed and plastering angle to achieve the plastering process.

Robot-Controlled Camera The workshop utilizes the IIWA Lady, a human-machine collaborative robot, to explore the spatial perception experience extended by the virtual space and create unique animation effects. This design uses Unreal Engine to create virtual scenes. It also utilizes TACO IIWA software to collaborate with robots, exchanges information with Unreal Engine in real-time. Eventually, control the rendering effects of its virtual cameras and animations. In detail, this study developed a custom interface between the ROSOCoop robots and Unreal Engine. Utilize the robot as an intuitive input device for real-time control of virtual cameras within the Unreal Engine scene. It controlled not only camera position/rotation but also focal length, speed, etc.

The traditional curved template is difficult to form quickly and accurately, and it needs to consume a lot of manufacturing costs, thus limiting the design possibilities. Based on the development of TACO robot software, it can communicate with external devices in real time. Then reposition and correct the surface by Hololens and infrared distance measurement to create a coupling between real and virtual models to form a digital twin model. Further simulate the composition and manufacture through the robotic printing system.

AAVS Osaka The appearance of the pavilion that comes from the unique law of proportions between components and the overall structure holds a very deep sig¬nificance in today's society. Furthermore, as the craftsman¬ship of constructing these pavilions was passed from era to era, aspects such as the law of proportions have been further improved on in conjunction with technological advancement. This workshop provides the opportunity to guess how the future of design will unfold by reconsidering how people, technology and tools are connected after we have a gained insight about traditional wood framework craftsmanship from a new perspective.

Roof is an essential part of the image skyline of the traditional city, and add the mass and the weight that the religious godas were designed to be looked from far away, the roof silhouette describes the proportion and the general design intentions of the building. Traditional Japanese architecture is based on the notion of proportion, function and beauty. The repetition of structual elements creates an hipnotic and beautiful architectural language that has became the esential of the structure.

RULED SURFACE Following the rotation of the reciprocal structure, the roof expands between the main structural members of the pagoda: the rafters, creating a ruled surface. The ruled surface is solved with a of the main structural members. Roof and tower structure are independent from each other so the design, fabrication and assembly of the roof could happen in paralel.

PROCESS Process was driven by material and assembly constrains. To accomodate the varying lenghts of Hinoki panels, primary members were extended by usact as a secondary structure to the roof, supporting primary members and lock-
