US 2022/0017165 A1 · ROBOT LEG STRUCTURE

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.
