Abstract
A landing shock absorbing devicedisposed in a foot mechanismof a leg of a robot, wherein an inflatable bag-like member(a variable capacity element) is provided at a ground-contacting face side of the foot mechanismThe bag-like memberis constructed of an elastic material such as rubber and has a restoring force. An interior portion of the bag-like memberis communicated with the atmosphere side through a flow passageDuring a landing motion of the leg, the bag-like membermakes contact with the ground to be compressed, and the air in the interior portion thereof flows out into the atmosphere through the flow passageso that its outflow resistance is generated. Accordingly, a landing shock is reduced. In a lifting state of the leg, the restoring force of the bag-like memberallows the bag-like memberto be inflated while the air flows into the interior portion thereof. An impact load during the landing of the leg of the legged mobile robot may smoothly be reduced in a light-weight configuration.
