Our plan is to put 4 CIMs in the drive-train. With single motor drive and trying to balance, especially attempting to push other robots on the ramp (single person controlling the balance instead of 2 or even 3. This is accomplished by a low level of stall by the other balancing robot against your robot, and then back-driving or sliding the other robot to control the balance.) would be all but impossible without either 2 speed gearboxes or a 4 CIM drive. I would recommend the CIM SIM from andymark as an alternative power method for flywheels, belts, conveyors, and other high power systems. A pair of 500 series motors will actually perform better than a single CIM in most cases, and with the gearbox is comparable on weight. I try to avoid the RS-775, because they don't offer the same benefit/weight as the other motors, designed properly, the fragility of some of the 500 series motors wont be a problem, and there are more gearbox options which allows for the possibility of keeping it lighter with more power.
