Go to Post Belts are a fine way of transferring power in a robot. Like chains, gears, drive shafts, viscous couplings or any other means of transmission they require some care and attention on you're part. But no one said this robot stuff was going to be a cake walk. - Andy A. [more]

With the given information, you should expect to see between 6.5 and 7.0 ft/sec.

In order to reach 31 ft/sec, you would need a final gear ratio between your CIM motors and the output wheels of aproximately 4:1, depending on where in the speed torque curve you would wish to operate at. For comparison, the first stage in the toughbox is 3.57:1.
