Machine Week 2023
everything's connected but nothing's working ! Your (Group) Task
Each section will design and build a "machine" - this means anything that includes mechanism, actuation, automation and application, that just means:
Mechanism: mechanical degrees-of-freedom (DOF)
Stuff shuld move around.
Actuation: computer-controllable motion of the above DOFs
The motion should be computer controlled.
Automation / Application software-coordinated computer-control of the above, and i.e. sequences therein
The motion should result in some desired outcome... maybe make something, draw something, change something, assemble something, sort something, cast a spell, etc.
We can also think more broadly about "tools" - what does it mean to build a computer-controlled system that acts like a tool, interacting with the world but being mediated by some designer's intent... it's a foamcore world.
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.
