Each section will design and build a "machine" - this means anything that includes **mechanism, actuation, automation and application**, that just means:
Each section will design and build a "machine" - this means anything that includes **mechanism, actuation, automation and application.**
You'll get a [**kit of parts**](KIT.md) to do this, and we have [**an example linear axis**](TODO) and [**an example rotary axis**](TODO) that you can use as building blocks. We also have two example projects: [**a xylophone that plays itself**](TODO) and a [**small, very fast drawing machine**](TODO). We also provide a [**set of modular hardware and software for motion control**](https://gitlab.cba.mit.edu/jakeread/machineweek-2024-control)(requires a gitlab login) to help get things moving.
### **Actuation:** computer-controllable motion of the above DOFs
The motion should be computer controlled.
You should also **document your machine** and **use git to collaborate** a-la last year's examples:
### **Automation / Application** software-coordinated computer-control of the above, and i.e. sequences therein
- CBA Section 2023: [repo](https://gitlab.cba.mit.edu/classes/863.23/CBA/machine) and [website](https://fab.cba.mit.edu/classes/863.23/CBA/machine/index.html)
- Harvard Section 2023: [repo](https://gitlab.cba.mit.edu/classes/863.23/Harvard/machine) and [website](https://fab.cba.mit.edu/classes/863.23/Harvard/machine/index.html)
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).
### **Actuation:** computer-controllable motion of the above DOFs
### **Automation / Application** software-coordinated computer-control of the above, to accomplish a task.
The motion should result in some desired outcome... maybe make something, draw something, change something, assemble something, sort something, cast a spell, etc.

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.
