Re: pic: VEX Mecanum Concept Wheel

Are those white nylon spacers your rollers? Just wondering, why are they so tiny?

About the curvature of the rollers, my team (FRC) built a set of custom mecanums last summer and we were originally going to CNC lathe the rollers, but we realized that rubber labstops were almost the same shape, squishy enough to conform to the floor, and much cheaper. They might not behave as well at the VEX scale though, I wouldn't know.
