Abstract
A body receives a lot of information of an environment and sends it to a brain. Thereafter, the body receives a signal corresponding to the movement and takes an action to the environment. It takes for granted that we focus on the body structure. We developed Bio-inspired Quadruped Robot. The robot has same size of a real cheetah and same Biologial-Plausible muscle moment arms. Its legs are driven by pneumatic artificial muscles. An experiment of a walk shows us a possibility that a biologic muscle-skeletal has a potentially stable walk function.
