A robot with an automatic charging function, comprising: a body, an arm mechanism rotatably connected to the body, a head mechanism and a driver rotatably connected to the arm mechanism; wherein a receiving space is formed in the body for receiving the arm mechanism; the head mechanism comprises two conduction terminals for receiving power from power outlets of a charging station; when power of the robot is lower than a preset level, the driver is configured to drive the arm mechanism to rotate out of the receiving space of the body, simultaneously, the driver is configured to drive the head mechanism to rotate relatively to the arm mechanism till the two conduction terminals of the head mechanism are electronically connected to the power outlets of the charge station, thereby receiving power from the charge station.
