As far as the power/turning ratio, my team sorta beat the system last year. We used one of the pneumatic pistons to lower a plate on which two casters were mounted. If we needed to turn quickly, we hit the trigger, dropped the plate, and it turned on a dime. For power, and to stay up on top of the ramp and to climb up the ramp, we'd raise the plate. This gave us the maximum power of our drivetrain design, with the added maneuverability of a two-wheel system.

comment on the whole ready-made chassis thing: I believe it takes away from the robotics experience. Part of the fun(and panic) is designing everything from scratch. Only time will tell what they're going to do
