Wind Vane Analysis & Design A wind indicator is the most important sensor on a sailboat. Sailors continuously monitor it while navigating and maneuvering. This study was motivated by the need to improve the intrinsic responsiveness of wind vanes. My final graduation project defines a design methodology for wind indicators, through mathematical modeling and prototype experimenting. New wind vanes have been designed for optimal performance and shorter response time than existing commercial vanes. Material density is a crucial parameter that creates a tradeoff between floatation and moment of inertia about It's rotation axis.

Modelling and testing

Static Stress Analysis

An equation of motion was derived to analytically represent the vane behavior. The mathematical model was proven to be a valid reference through experimentation. A new wind vane was designed in the light of the characteristic parameters of the vane.

Simulation of an aerodynamic force applied at the aerodynamic center of the vane. The wind pressure !=0.5"#^2, wind speed #=10 $/%, and lift coefficient &=2'(_0, yield an aerodynamic force )_*=&+, respectively equal to 0.20N for the Falcon and 0.14N for the Wingman.

Robotic Gripper

Plans

During my exchange semester at the Sorbonne Université in Paris, I took a course in technical drawing and computer aided design. As an intermediate project I developed a functioning robotic gripper to be 3D printed in ABS plastic. This was an individual work, which consisted in two weeks of researching, sketching, virtual prototyping, rapid prototyping and testing. The claw is semi-symmetrical. It is composed of 5 parts, each of which is uniquely designed to be self intersecting with it’s similar. With a total of four revolute and one prismatic kinematic pair, the configuration is less prone to failure and has lower friction compared to others which do not share a common joint. Design constraints: • • • • • •

1 degree of freedom motion described by an input translation to an output rotation of the arms Maximum mass of 80g Balanced rotation around input axis Minimal distance between plane surfaces of 0.3mm Minimal distance between surfaces of a revolute pair of 0.5mm Maximum size for printing of 150x150x150mm

Plans for two parts shown.

Custom LEGO Technic Models Over the years, I have been passionate about creating custom working LEGO models. I design and build them from scratch, not from a set and without instructions. Among my numerous creations, this is one of my favorite, inspired by the Mercedes-Benz Unimog. The first step of the design consists in researching and understanding the motion of the real vehicle. I conceptualize the mechanisms, parts arrangements, chassis, suspensions, gears while considering the context and application: whether on- or off-road. Aesthetic decisions include the choice of the most similar LEGO parts and panels for the exterior. After defining the proportions of the vehicle and converting the dimensions to LEGO units, an approximate virtual prototype of the drivetrain is created using LEGO Digital Designer. On this basis the model is then built and tested for off-road performance. This particular model features front and rear fully independent suspensions, 4WD and Ackerman steering. The model mounts two electric motors, a battery pack and an IR receivers.

LIFT

Life Isn’t For Tra!c

Business at School Rome 2014 Liceo M. Massimo:

Alessandro Ceccarelli, Giulio Coria, Renato Cortesini, Alessandro Croccolo, Filippo Pesci, Francesco Romagnoli, Matteo Sammarco.

I was selected on graded ranking from the Istituto Massimiliano Massimo High School in Rome for the Business@School project: an extra-curricular activity organized by the Boston Consulting Group. This project was conducted with a team of other five students from my school. After exploring how to write a business plan, analyze companies and create values for customers, we developed LIFT, an instant urban car pooling service which operates within a variety of customers providing safety and efficiency. We won the regional competition, then competed in Milan for the national finals. With real customer advantages, it offers a possible solution towards Rome’s current traffic issues. The vision is to become the leading car pooling company in Italy in terms of efficiency, immediacy and safety. The project included research, brainstorming sessions, context analysis and interviews with perspective users. A survey was conducted to investigate the adoption of such service and which would be the most important feature among price, quality and safety. Lastly, we asked what would be the primary use of LIFT whether for work / Uni, Events (gigs / football matches) or daily routines. Together with the general development, my responsibilities were the following: • • • •

Development of business model (method of operation, safety, advantages). Analysis of market opportunities (market share, customers, competitors). User interface and graphic design of the presentation. Keynote speaker

The topics of the final presentation are: executive summary, business model, market opportunities, value chain, company structure, financials & scenarios, SWOT.

Video Production As a part-time job I create films, photos and graphics for water-sport activities, sailing events, and companies. I also manage a YouTube channel that counts half a million views and 2k subscribers. My goal is to create the most unpredictable and unseen camera angles. Filming in the elements at sea is challenging, it requires experience and preparation. During the shooting and editing processes, I am inspired and guided by the motion of water droplets and waves. I allow the water to guide the transitions and flow smoothly from one scene to another. Responsibilities: • Director of photography • Camera operator • Editor and post-producer • Publisher www.youtube.com/sammaproductions

University of Rome Tor Vergata logo proposal Description: In 2009 the University of Rome Tor Vergata launched an ideas contest for the adoption of a new logo. Unfortunately, I was late for the competition, so I decided to pursue this in 2019 as an individual project. This is my attempt to modernize the image of my university for todayâ&#x20AC;&#x2122;s digital era.

LOGO WITH SHADING

The proposed logo is bold and rational. It maintains the two symbols of the institution: the capital letter U, the medieval tower and the color green. The toponym of Tor Vergata refers to a tower built with alternating bands of tuff and bricks.

INTERACTION ICONS

The new shade of green is a symbol of the nature and fields that surround the university campus. The logo is simple, memorable and scalable. It can be used with different weights, making it versatile for any web device or print material.
