Jason, we built your robot's little brother for the VRC competition. OK, it's actually a rolling chassis that was done as a technical demonstrator and proof of concept, and has not been mated to a game system, but it could be. It consists of a pair of power modules, each of which consists of two 4" wheels, two drive motors, and a 2-speed transmission which shifts with a servo. Either each module can have its own shifting servo, or a long drive shaft can run across the middle to the other side to shift both sides mechanically. The width of the robot is determined by the length of the rails chosen to connect the modules.

EDITED: You know, if those drive modules are six inches wide and made of plywood, permanently mount noodles and viola! instant bumper legality!
