Rail robot and real-time positioning system thereof

The invention discloses a rail robot and a real-time positioning system thereof.The rail robot comprises a robot body and a shading sleeve arranged on the robot body, the shading sleeve is arranged on the robot body in a sliding mode in the axial direction, and a color sensor is fixedly installed in the shading sleeve; the first end of the shading sleeve is provided with an elastic piece, the second end of the shading sleeve tightly abuts against the track through the elastic piece, and the color sensor is used for collecting color information of the track at the real-time position of the track robot and color information of the initial position of the track robot. The positioning mode of the rail robot is more accurate, meanwhile, the rail robot is more convenient, and the positioning effect can be achieved when the rail robot is started at any position. In addition, through the effect of an elastic piece and a shading sleeve arranged on the color sensor, the collection effect of the color sensor is better,
