Brake mechanism of robot using multi-output differential gear

Abstract

A brake mechanism of a robot using a multi-output differential gear, capable of selectively blocking or applying driving force as needed, the brake mechanism including, a differential gear unit receiving driving force and generating at least three outputs differentiated from the driving force while being linked with the driving force, a driving unit transferring the driving force to the differential gear unit and moving in a direction away from or approaching the differential gear unit to thereby be detachably provided in the differential gear unit, and a rescuing unit controlling a spaced distance between the driving unit and the differential gear unit to attach and detach the driving unit to and from the differential gear unit.
