Re: Coefficient of Frictions

Here are the results of a test we did for RoboCup. This tested rubber on a felt carpet. It is similar to the FIRST carpet... This data is very good for comparison, but take the values themselves lightly, since the shape of the wheel and the carpet material will be different for FIRST use.

Buna-N: 1.29
Neoprene: 1.60
EPDM: 1.44
Viton: 1.11
Silicone: < 1.29 (not sure of exact value, but it is definately less)
