			# 4. Strategies

			- teamworks!
			- have a project manager
			- divide into sub-teams, but talk often
			- electronics / software
			- mechanism
			- documentation
			- cad/cam ?
			- prototype in cardboard, mechanisms can move 'by hand'
			- 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

			- 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
