All robots were required to use certain wheels for their floor-contacting propulsion--the CoF between said wheels and the floor was something just under 1 as I recall, while your typical nitrile wheels are 1.something-or-other. Unlimited quantity... but that was the ONLY type allowed! Low-traction game, low-speed, low-friction...And then there were the trailers, but I'll end there.

Just under 1 is the CoF of the 2008 Kit wheels, if memory serves, which were a bit slicker than other years. The CoF of lunacy wheels on FRP was reportedly 0.06, though it was probably 2 or 3 times that on a worn field.
