Re: Coefficient of Friction on Carpet?
The traction gain is almost negligible.
our raw data:
14lb dynamic (wheels slipping) pull, 60lb robot, 4wd, "smooth/regolith/etc"
16lb dynamic (wheels slipping) pull, 60lb robot, 4wd, "carpet"
that's an extra 2lb of pull while slipping, and I think the breakaway point is pretty close to 2lb extra as well (16lb smooth, 18lb carpet).
tl;dr: the problem isn't so much the floor surface as the smooth wheels.
