Abstract: A servo assembly includes a housing, a motor, a control circuit board and a gear transmission mechanism that are arranged in the housing. The motor is electrically connected with the control circuit board. The gear transmission mechanism is rotatably connected with a motor output shaft of the motor and the servo output shaft. A servo output shaft has one end that is received in the housing and located above the control circuit board and an opposite end that extends out of the housing. A servo plate is connected to the end of the servo output shaft which is away from the control circuit board. The servo plate includes a connecting portion connected with the servo output shaft. An annular member is disposed between an end surface of the connecting portion and the housing, and the annular member is used to limit an abnormal rotation of the servo output shaft.

Abstract: The present disclosure relates to a recharging robot system. The recharging robot system may include a signal emission device including at least one signal emission channel. The at least one signal emission channel each comprises an opening. A distance between two central axes of any two adjacent signal emission channels is gradually increased along a direction facing away the signal emitters. As such, an overlapping area of signal ranges of the at least two signal emitters may be reduced, and the robot may accurately determine which signal range that the robot is within, so as to accurately align with the recharging dock.

Abstract: A robot includes a body having a torso, a pair of arms and servos configured to drive the arms. A first end of each of the arms is movably connected to the torso via a corresponding one of the servos. An opposite, second end of each of the arms is connected with a hand. A first connection member is arranged on the body. A fake gun includes a second connection member that is magnetically attractable to the first connection member, and is connected to the body when the second connection member is attracted to the first connection member. One of the arms is rotatable and the hand of the one of the arms and the fake gun are configured in such a way that fake gun is detachably connected to the hand of the one of the arms when the one of the arms is rotated to a predetermined position.
