For those that don't get the reference... 2009 (Lunacy) was played on a field of Glassliner FRP with about a foot of carpet on all sides next to the rail. If you want to know what that looks/feels like, there's probably something similar in your nearest school/park restroom (as an anti-graffiti/easy-clean sort of measure). 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.
I was far under 1 iirc. The regular tread wheels get around 1.
