Did you get a look at 343 Metal in Motion's wheels? We had 6 main wheels each with 16 smaller wheels arranged at 90 degrees to the direction of rotation. That's 102 wheels in all. We called them unidirectional wheels because they only generate force in one direction. Four of the wheels were used to drive forward and back and the other two set 90 degrees from the those to drive side to side. Our control system allowed two modes of operation. The first worked like a tank drive with the assist of the side to side wheels for turning. The other mode ( activated by a button on the joy stick) allowed us to move independently front to back and side to side. This scheme made it nearly impossible to pin us and gave us a nifty advantage moving the goals around.
