To provide a landing shock absorber capable of securing the stability of the posture of a leg type mobile robot with ease while reducing the shock load when the leg body of the robot lands to the walking posture of the robot properly and constituting the robot itself lightly.
The landing shock absorber 18 arranged in the sole mechanism 6 of the robot is provided with a bag-like member 19 (variable volume body) which can expand and compressed in relation to the bottom face side of the sole mechanism 6. The bag-like member 19 is made of elastic material such as rubber. Atmospheric air can flow into and out from the bag-like member 19 through a flowing in and out passage 20 provided with a solenoid valve 27, etc. With the sole mechanism 6 separated from floor, the height of the bag-like member 19 in its final expansion state is controlled according to the walking posture of the robot by controlling the flowing of air into the bag-like member 19.
