The invention belongs to the special robot field, and concretely provides a track self-directed moving robot. The robot comprises steering frames, a chassis, a current collector, travel switches, a holder, a control system, a slide wire and positioning blocks. The two steering frames with the same structure are mutually independent and move on a track respectively. The slide wire which is connected with an external power supply is arranged on the track, and a multiple sets of positioning blocks are symmetrically arranged on two sides of the slide wire. The chassis is connected with the two steering frames respectively. The holder and the control system are respectively mounted on an upper surface of the chassis. The current collector and travel switches are respectively connected to a lower surface of the chassis. The current collector slides on the slide wire and supplies power to the robot. The travel switches are arranged on two sides of the current collector and the moving tracks of the travel switches are corresponding to installing positions of the positioning blocks. The current collector and the travel switches are respectively electrically connected with the control system. The robot of the present invention ensures the control of precise walking and positioning and the like on a planned track path, and continuous fixed-point observation of a plurality of targets can be realized.
