Target automatic positioning robot for measuring parallelism

A target automatic positioning robot for measuring parallelism comprises a target mechanism, a platform frame, a guide wheel mechanism, a wheel mechanism, a vertical translation mechanism and a control mechanism, the guide wheel mechanism, the wheel mechanism, the vertical translation mechanism and the control mechanism are arranged on the platform frame, the target mechanism is connected with the vertical translation mechanism, and the vertical translation mechanism is arranged at the front end of the platform frame. A guide wheel mechanism used for controlling the robot to move along the reference surface and a wheel mechanism used for driving the robot to move in the box body are correspondingly arranged at four corners of the upper surface and the lower surface of the platform frame respectively; and the control mechanism is respectively connected with the guide wheel mechanism and the vertical translation mechanism to realize the control and signal processing of each driving motor and the communication w
