Our rookie year (Toroid Terror) we used a rocking concept, but with only 2 wheel drive. We ran two wheels at the center of the robot and then in the center of the front and back, we used small fiberglass skids (and inch or two in radius). The skids were raised slightly off the floor so that the robot rocked (like Dr. Joe's 6 wheel drive). We only weighed 70 lbs, but we were easily one of the fastest and most manuverable robots out there.
We discovered the major flaw with this system the next year. That year we tried virtually the same drive system, but the robot weighed 130 lbs. In this case, there was too much weight on the skids and the robot barely moved.
Dr. Joe's 6-wheel drive solves the problem above by having more driven wheels on the ground. I would definetly consider trying it if I were you. It gives you a strong, manuverable robot, and you can easily be fast if you want to also.
