摘要

The invention relates to a secure, motor-driven hinge to be mounted between a first and second member of a humanoid robot, characterized in that said hinge includes: a motor (21) including a stationary portion (25), to be connected to the first member, and a movable portion (26), movable relative to the stationary portion (25) and intended for connecting to the second member relative to the first member; a brake (22) capable of exerting a force on the movable portion (26) of the motor (21) by means of a spring effect, such as to prevent the movable portion (26) from moving relative to the stationary portion (25); and an actuator (23) capable of moving the brake (22) by opposing the spring effect such as to release the movable portion (26) of the engine (25) from the force of the brake (22) and enabling the motor (21) to move the movable portion (26) relative to the stationary portion (25).
