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)
### **Actuation:** computer-controllable motion of the above DOFs
### **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.
> [Ilan](https://web.mit.edu/imoyer/www/index.html) (inventor of [CoreXY](http://www.corexy.com/)) would urge us to think more carefully 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](https://web.mit.edu/imoyer/www/portfolio/foamcore/index.html).

### Turn-By-Wire [[UIST](https://dl.acm.org/doi/abs/10.1145/3332165.3347918)]

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.

- teamworks!
- have a project manager
- divide into sub-teams, but talk often
- electronics / software
- mechanism
- documentation
- cad/cam ?
- commit to your vision (no backtracking)
- spiral development !
- document all the time, it should be one person's job !
- one page per team,
- note individual contributions on your page

# 7. What to Do Now
- elect a contact-person (or dictator)
- have them contact us (Jake and Quentin) (contact info will be in a gitlab issue)
- convene a kickoff meeting, schedule it with us!
- kits, demos, and more to come...
