Exercise 15: Mechanical Design
Group assignment
- design a
machine that includes mechanism+actuation+automation
- build the mechanical parts and operate it manually
- document the group project and your individual contribution
Learning outcomes:
- Work and communicate effectively in a team and independently.
- Design, plan and build a system.
- Analyse and solve technical problems.
- Recognise opportunities for improvements in the design.
Have you:
- Shown how your team planned and executed the project.
- Described problems and how the team solved them.
- Listed future development opportunities for this project.
- Included your design files, 1 min video (1920x1080 HTML5 MP4) + slide (1920x1080 PNG).
Our team
In this project, we are a group of seven students: six at Opendot, Milan, and one student at Crunch Lab, San Dona’ di Piave (VE).
Brainstorming and team building
Last week, we met at Opendot and talked together about a machine which does something, and in its parts can be useful to our individual final projects.
We thought of a ping pong ball shooter to a moving target., and after a brainstorming, we chose to built two machines:
- a ping pong ball launcher that will point a guided direction, raising its board and launching the ball through rotating wheels, and a guideline, and will shoot the ping pong balls, built by Laura Cipriani and Massimiliano D'Angelo for the mechanical design; Gianluca De Rossi and Federica Selleri for the machine design;
- a remote-controlled target robot which will move at random, stopping and going alternatively, built by Alberto Ongari and Catherine Blanchard for the mechanical design; Francesco Pasino for the machine design.
- Both machines will dialogue through a bluetooth communication system
We are very excited! It is almost four months we study and practice together and we feel a team.
We understand it is a great deal of complexity and a new adventure to be lived together.
Inspiration
Some of us love soccer, and were fascinated by a professional ball shot machine like the
Globus EuroGoal one. Some others love robots, so they thought that the target could be a basket fixed on a remote-controlled mobile robot.

This
video about a tennis ball launcher helped in the development of the prototype.
The parts of the ping pong ball launcher
- The central part is the board
- The top of the board
The board will receive on the top:

the sponge gasket has been chosen.
- The bottom of the board
The board will receive on the bottom:
- Two 3D printed motor supports
- Two motors
- Lateral view of the bottom

- The 3D printed basket
It will be fixed on the central part of the top of the robot body, and connected to the a sensor, thanks to the hole at its extremity.
