BTW, don't use mecanum on dusty dirt, you are asking for trouble. The roller "bearings" will get contaminated and it won't operate properly any more.

The wheel can still function as a mecanum but at a reduced performance - only some of the rollers are sticky or stuck. With our Breakaway bot it still ran fairly well even though some of the roller shafts were bent.
