One of the two basic skid steer drive trains included in the kit of parts is designed to utilize one or two CIM motors on each side of the robot. This exact motor has been known over the years as the "CIM", "Chiaphua", or "Atwood" motor. The motor is provided in the kit of parts as part number "FR801-001". Some years have also shipped a larger three inch "Mini-bike" motor (part number FP801-005).

Usage Notes
- Partially because of the CIM's relatively large size and consequentially low power density, the motor can withstand longer periods at, or near, stall. CIM do not burn out nearly as often as a drill motor or a fisher price motor.
- Because the CIM is not designed for a specific application like the (obsolete) drill motor, it has little or no wiring bias. This means the motor is equally powerful in forward in reverse. This can be useful in many applications. For example, drive trains which involve a pair of motors running in opposite directions can suffer from driving in a large radius circle when both motors are set to equal speeds. The CIM is relatively immune from such problems in that situation.
