Abstract: Provided is a robot leg structure that includes a link extending downward from a leg joint, a ground contact portion that comes in contact with a ground, a leaf spring that couples the link and the ground contact portion to each other, and a damping member adjacent to the leaf spring and couples the link and the ground contact portion to each other. With this configuration, the damping member damps the vibration attributed to the leaf spring, making it possible to reliably stabilize the motion of the legs of a robot.
