Six-freedom remote control arm with gravity compensation and length regulation

The present invention relates to data arm mechanism for remote operation job of robot. The data arm mechanism is one mechanical arm with six rotating joints, and each of rotating joints is provided with one potentiometer as angle sensor. The data arm has gravitational compensation mechanism and may be worn by operator for leading motion or may be drawn to required state without being worn, and it may stop in any position without need of auxiliary outside force. The data arm has length regulating mechanism for person of different arm length to wear. The present invention can detect the rotation angles of total six freedoms of the shoulder joint, elbow joint and wrist joint of the operator, and is suitable for control platform of remote operated robot and for being worn onto arm of the operator.
