These drives are manufactured with simple planetary principle with internal arrangement for reduction in backlash which may occur due to wear of components. These drives are available in different models suitable for Servo Motor input and backlash is controlled to 8 arc minutes.

The principle of the Cyclo Robotic Drive is based on a simple planetary gear mechanism. The simple planetary gearbox comprises of sun gear, planet, planet carrier assembly that comprises of carrier and the planets rotating at constant centers along with the planet carrier. The input is from the sun gear and the drive motion through the planet carrier via planets and the ring gear is stationary. The rolling contact of the planets with the ring gear provides the appropriate reduction ratio.

Cypla Robotic Drives offer high level of output and torque transmission in compact and space saving design. Cyclo Robotic Drives have the following features:

	Coaxial arrangement of input and output shafts.
	Input and output direction of rotation is same.
	High efficiency.
	Compact design.
	High power to weight ratio.
	Minimal sensitivity to shocks.
	Low noise.
	Easy to maintain.
	Easy to fit and adaptable to any motor.
	Low backlash up to 5 arc-minutes.
	Grease filled, so can be mounted in any orientation.
	The input sun gear is directly mounted on the  motor shaft hence compact.
