Re: Chainless Mecanum Drive
12.75:1 is the default gear ratio for the AM toughboxes and toughbox-derived gearboxes (Nano, etc.)
12.75:1 is the ratio between the input (in this case the output of a CIM motor) and the output (The output shaft sprocket or direct-driven wheel). With it you can find the output speed and torque of a gearbox if you know the speed and torque of the motors going into it.
If you need the long output shafts (you might not) you would have to get new long output shafts from AndyMark and put them in the existing toughboxes.
