Abstract
A landing shock absorbing devicedisposed in a foot mechanismof a leg of a robot, wherein an inflatable bag-like member(variable capacity element) is provided at a bottom face side of the foot mechanism. The bag-like memberis constructed of an elastic material such as rubber. The air in atmosphere may flow into and out of the bag-like memberby inflow/outflow meansequipped with a solenoid valve, and the like. In a lifting state of the foot mechanism, inflow of the air into the bag-like memberis controlled, thereby controlling the final height of the bag-like memberin an inflated state to the height in response to a gait type of the robot. While properly reducing an impact load during a landing motion of the leg of a legged mobile robot depending on the gait type of the robot, stability of a posture of the robot may easily be secured, resulting in allowing a configuration to be lighter in weight.
