KnightKrawler used 2 AndyMark Nano Tube 20's with hex shafts in the stock 12.75:1 ratio. One CIM per wheel and each wheel driven directly from the gearbox. Since we need a drive motor per wheel, we used this as an opportunity to leave out chain. The wheels are AndyMark 8" HD mecanums that come with side rollers which we do think help to smooth out the movement of the robot as it transitions between mecanum rollers.
