Yes thats exactly how it works. As to the retracting part. It would have to involve a mechanical function so i can keep the motors to a minimum. I want it to come around back so it can clear stairs and such objects. Finally, If I added wheels to the end of legs it would need to be some type of pulley system and then again I run into having more then two motors a leg.
