Abstract: A robot leg structure includes: a link 500 extending downward from a leg joint; a ground contact portion 600 that comes in contact with a ground, a leaf spring 300 that couples the link 500 and the ground contact portion 600 to each other; and a damping member 400 arranged to be adjacent to the leaf spring 300 and configured to couple the link 500 and the ground contact portion 600 to each other. With this configuration, the damping member 400 damps the vibration attributed to the leaf spring 300, making it possible to reliably stabilize the motion of the legs of a robot.

Abstract: A suitable posture according to a shape of a traveling surface of a robot can be stored in a storage, the suitable posture according to the shape of the traveling surface can be acquired from the storage when the robot is to be stopped, and posture control can be performed to stop the robot. A suitable stop posture analyzer that analyzes the suitable stop posture of a walking robot executes processing of analyzing the shape of the traveling surface of the walking robot, stop posture analysis processing of analyzing stop postures according to the shape of the traveling surface, stop posture evaluation value calculation processing of calculating evaluation values of the stop postures, and processing of recording, in the storage, a stop posture having a highest evaluation value among the stop postures according to the traveling surface shape. Furthermore, a stop control unit acquires the suitable stop posture corresponding to a traveling surface shape clustering group from the storage, and performs posture control to match a posture of the robot to the suitable stop posture and stop the robot.
