A communication assembly used for being in communication connection with the robot and a base station is arranged at the top of the body. A fixing assembly used for fixedly connecting the robot mother port to a terminal tower is arranged at the bottom of the body. A door used for opening or closing the cavity is arranged on the front side wall of the cavity. A charging assembly used for charging the robot is arranged on the bottom wall of the cavity. The mother port is simple in structure, and after the robot enters the cavity, the door is closed, so that the robot is in a totally closed environment after entering the robot mother port, and the safety is high. The stability of communication among the robot, the robot mother port and the body can be ensured through the communication assembly. In addition, the robot mother port can be fixedly connected to a terminal tower through the fixing assembly safely and stably.
