Abstract
The purpose of this research is to develop a trampoline gymnast robot which can do some maneuvers such as straight bounce and somersault performance. We already made study about straight bounce for the trampoline robot system constructed. In this report, some simulation analyses are made for realizing somersault by manipulating the angular momentum at take-off instance and controlling the moment of inertia of the robot in the air. The relation between angular momentum and the moment of inertia of the robot is studied, and the availability of somersault is examined.
