The answer is this folks: These are 6" elevator guide wheels with a medium rubber bonded to the rim. We made custom hubs and voila, there we go. the bevel on the rubber works so that the more the wheel spins, the smaller the wheel gets: this gives us more torque. It also means that we have more rubber touching the the carpet for more traction. the more the wheels spin, the more our robot adapts to stop the wheels from spinning.

If it's falling apart it's a mechanical problem. If it's spewing smoke it's a electrical problem.
If it's rampaging around destroying things it's a programming problem.
