Abstract: A brake assembly for a servo including a motor includes: a brake disk fixed to and rotatable together with the output shaft of the motor of the servo, the brake disk having a lateral wall defining at least one opening; and a linear motion actuator including a plunger and an elastic member. The plunger sides from a first position where a first end of the plunger is received in the at least one opening to a second position where the first end of the plunger is disengaged from the brake disk when the linear motion actuator is energized. The elastic member applies an elastic force to cause the plunger to slide from the second position to the first position when the linear motion actuator is deenergized so as to stop rotation of the output shaft of the motor.

Abstract: A robot head rotating structure includes a housing, a fixing frame, a connection assembly, and a rotary driving apparatus. The housing defines an internal space. The fixing frame is disposed in the internal space. The connection assembly is disposed between the housing and the fixing frame. The rotary driving apparatus is disposed in the internal space. In comparison with the prior art, the robot head rotating structure has the connection assembly disposed between the housing and the fixing frame as well as the rotary driving apparatus, which are capable of enabling the housing to rotate with respect to the fixing frame. As a result, the head of the robot is capable of swinging back and forth as the head of a human stably, and the raising and bowing of the head of the robot can be realized, which improves the automation of the robot.
