An automatic manipulator apparatus is disclosed in this invention. The automatic linear actuator of this manipulator can extend or shrink its length. By using the principle of multiple pulleys, the manipulator, with a rope wound above the first pulley and beneath the second pulley, can elevate or lower the load, such as a test head. When the automatic linear actuator extends, the first pulley generates a displacement, and the load obtains a double displacement at the same time. As a result, the height of the automatic manipulator can be decreased.
