Human knee joint has a yaw-axis rotational DOF and a locking mechanism called screw-home mechanism. We focus on this mechanism and implement it to a musculoskeletal humanoid through hardware design.

We are trying to create a novel musculoskeletal humanoid robot which has a humanlike structure. In this paper, we present a new knee joint which is usually simplified in robotics for high ...

Weevils are screwed up. Their legs are, anyway. The beetles are the first animals found to have a screw-and-nut mechanism in their bodies. Poring over CT scans of the Papua New Guinea species ...
