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!)
Layering / Interfacing
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.
Label Maker
Wire Cutter
Music Machines
String / Floating Machines
Architecture-Scale / Space Transforming
Claw Machine
Robot Chainsaw Machine
Robot Basketball Hoop
Strategies
- use interfaces / modularity to split work up,
- keep your parts, and your tools, organized
- have a group chat ! invite your TAs !
Hardware
Composable Axis
Composable Rotary
- Rotary Axis (placeholder)
Extrusions, Brackets, etc
- structure, etc

Electronics / Software
based on urumbu, which are also available to use, we are supplying circuits and examples for modular-thing of which there are many circuits
