Title:
ROBOT LEG STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/116214
Kind Code:
A1
Abstract:
The present invention comprises: a link 500 that extends downward from a leg joint; a ground contacting part 600 that contacts the ground; a plate spring 300 that joins the link 500 and the ground contacting part 600; and a damping member 400 that is disposed adjacent to the plate spring 300 and that joins the link 500 and the ground contacting part 600. Due to this configuration, it is possible to reliably stabilize the movement of the leg of a robot as a result of the damping member damping vibrations from the plate spring 300.
