lists the coefficient of friction of rubber on solids as being 1-4. That is for a smooth rubber strip on a smooth solid. A coefficient of friction of 2 on carpet is highly possible. |
They are using 2 pairs of IFI traction tread (I would guess the wheels as well but we all know what happens with assumptions) and Andymark omnis (1 pair offset per side) in the front. The CoF of these wheels has been measured on carpet of the type used in FRC competitions and it is much closer to 1 than 2
