Abstract: A servo includes a motor, an output shaft used to drive an external component and having an external lateral surface, a gear set arranged between the motor and the output shaft and used to transmit power from the motor to the output shaft. The gear set includes an output gear arranged around the output shaft. The output gear defines a through hole that allows the output shaft to pass therethrough. The through hole has an internal lateral surface facing the external lateral surface. The servo further includes a connection ring arranged around the output shaft between the external lateral surface and the internal lateral surface. The connection ring is used to connect the output gear to the output shaft when a load placed on the output shaft is less than a preset value, and disconnect the output gear from the output shaft when the load exceeds the preset value.

Abstract: The present disclosure discloses a robot recharge control method, a robot and a robot system. The robot recharge control method includes: moving a robot to a first position of one of two edge lines of a preset detection signal region; moving the robot from the first position to a second position of the other edge line of the preset detection signal region; moving the robot from the second position to a midpoint of a line connecting the first position and the second position; and moving the robot from the midpoint to the dock section of the charging base. By detecting the two edge lines of the preset detection signal region, the first position and the second position which are axisymmetric with respect to the dock section are found, and then a center point corresponding to the dock section is found through the first position and the second position.
