What is the coefficient of friction for a 130lb robot (I hope they don't raise the weight limit next year.) on standard FIRST carpet (I hope they don't change that either.) with normal kit skyway wheels?
with Colson wheels?
with IFI traction wheels (roughtop/wedgetop)?
with polyurethane wheels (any specific durometer)?

Skyways - ~0.8
Colsons - ~1.0-1.2
Roughtop/Wedgetop - ~1.2-1.4
Those are the benchmarks I use.
