COMPLIANT JOINT

摘要

A compliant joint is provided to control the position of a robot arm accurately by giving the robot arm rigidity against an external force less than the specific magnitude. A compliant joint comprises a housing(10), a rotating member(20), and a cam(30). The rotating member is mounted on the housing to be rotatable. The cam holds or releases the junction between the housing and the rotating member depending on the magnitude of external force applied to the rotating member. The cam rotates together with the rotating member or moves in the axial direction independent of the rotating member.
