	Minibot is in CAD, so now we know what parts must be manufactured. Start/stop/reverse switches will be located tonight. A pivot with surgical tubing will snap the two wheels onto the tower when the minibot is shoved against the tower. Will build the basic design and see what the speed is, then alter it if necessary (gearing etc.).  Will have the two wheels, plus a switch, that all hit the plate at the top of the tower in a "tripod" formation.  Probably will add a fuse to keep motors from burning out.  What happens if the motor reverses after the minibot hits the top, and then it drives all the way to the bottom - what turns it off at the bottom?<br>		Minibot is in CAD, so now we know what parts must be manufactured.
