## Rec 1
- bring each example axis
- bring the blot
- bring one kit
- image of each thing / notes on hardware
- past years' work ...
- other resources
... should be ...
- what you'll have to do,
- mechanism,
- actuation,
- automation,
- what this normally involves, architecturally ?
- it's the mess, but don't scare them ?
- what are some fun ideas for machines we can build ?
- scale can be small (remember you're going to bring the thing to class)
- it can be simple (remember you have only a week!)
- what are some good resources ?
- we have prepared some,
- incld. machine class content, of which... meche,
- incld. our example axes, etc,
- others have,
- slocum, ...
- open builds ?
- what you should do:
- elect a Machine Dictator (you can deploy democratic process internally, we want to have one point person)
- have them contact Jake (WhatsApp) (617 230 0791) (jake.read@cba.mit.edu)
- and Quentin
- convene a meeting to decide:
- what to build, who to do what, when to work together, etc,
- invite us to the first meeting,
- we will bring you your kit of stuff to that first meeting
## Rec 2
... a walkthrough of some nuts-and-bolts demos,
- the xylophone,
- requires a representation of the plan (the sequencer)
- and an interface to it,
- requires some planning (when can we hit... what?)
- requires some actuation,
- and mechanical design...
- the scara-arm
- ... requires some kinematics, etc,
- the resources are, broadly,
- modules (of which any arduino project can become one such)
- mechanical bits and bops
- adjoints
- the extrusions use slide-in nuts,
- we commonly print 4.4mm hole to self-thread an M5,
- more beef wants hex inserts
