A chip and a Fisher Price?!? Talk about Power! I hope that it was only for tank drive.

During the 2002 season, 461 made a set of crab-treads (a great drive train, before considering weight), where two were powered by one chip each and the other two were powered by a FP and a Drill each. The FiP didn't work well, since it had plastic gears that couldn't handle competition torque. We ended up just using the drill, and the drive itself worked pretty well. I will look into getting an inventor/auto-cad file for the teams who think they can do four systems (what we did) in less than 50 pounds. A word of advice: while it may seem "cool" and "awesome" to put a 50 pound drive system, the frame better be welded, thin-walled box aluminum and the arms must be light...Very light.
