The Task
Each section will design and build a "machine" - this means anything that includes mechanism, actuation, automation and application, so:
Mechanism: mechanical degrees-of-freedom (DOF)
Actuation: computer-controllable motion of the above DOFs
Automation: software-coordinated computer-control of the above, and i.e. sequences therein
Application: pipelines from desired (designed) outcomes (shapes generated, patterns drawn, parts picked-and-placed etc), to actual outcomes (real stuff!)
Examples / Ideas
The machines you design and build don't need to be complicated - try to de-risk ideas early, and do stuff that "works right away" rather than complex projects that require hundreds of details to come together all at once in order to work. This can be fun; have fun.
