TeamUR Robo-Project Illustrated

After long search of a relatively cheap solution for the robot drive system we found those subminiature plastic sprockets and chain. The supplier, which is selling this cool stuff is McMaster-Carr. For TeamUR the Second and TeamUR the Third we used 6 sprockets and nearly 1 foot of the chain. We are NOT selling those items!

The main problem with the sprockets is that the inside diameter is smaller than specified (at least for 1/8'' and 3/8''). The coincidence that the available brass tubing had outside diameter bigger than nominal caused that we had to spend some time with a file and sandpaper working on the tubing... Anyway we think that it was worth.

	The item number of these really cool parts are for example: - sprockets: 64205 K71, 64205 K731 (approx. $2 per piece) - chain: 64205 K712 ($10+ per foot)
	The very precise chain is made of high quality plastic.
	It is very easy to disconnect with a small screwdriver, remove/add a piece of chain and connect again!
	It is not difficult to imagine any possible set of the sprockets.
	Perhaps this way? See Teamur the Second for the usage details.

The main problem with the plastic chain is that it doesn't give too much traction. In TeamUR the Third's suspension finally we ended up with attaching the rubber band to the chain what perhaps doesn't look cool but it works!
