The kit of parts in 2005 includes four CIM (Chiaphua or Atwood) motors. (Previously, it only included two.) One of the two basic skid steer drive trains included in the kit of parts in 2005 is designed to utilize one or two chiaphuas on each side of the robot.

2006
Two of the four CIM motors were replaced with the larger "motorbike" motors.

2007
Two of the standard 2.5" motors are included, and a larger 3" CIM.

Usage Notes
- Partially because of the Chiaphua's relatively large size and consequentially low power density, the motor can withstand longer periods at, or near, stall. Chiaphuas do not burn out nearly as often as a drill motor or a fisher price motor.
- Because the Chiaphua 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, drivetrains 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 Chiaphua is relatively immune from such problems in that situation.
