This 2007 robot has a three-wheel (what we call) "articulated" crab drive system. All wheels are driven with CIM motors and steered independently. The regular steering configuration is such that the wheels drive around the center of the robot, i.e., when it turns right, the front wheels go right and the back wheel turns left. Then crab is all in the same direction, of course. The crab drive is pretty handy for getting out of the corners with the trailer. This robot is not driving very well, because we just threw the wheels on and the software needs tweaking, but those guys are busy with the new design!

(I hope my answer isn't too lame, I am the HoF/business group mentor. The technical guy around the house is soundly asleep in his chair - we just got home from the shop.)
