Dynamics Modeling and Control Strategy of Force Telepresence System

Regulation of arm dynamics of a master slave robot system is effective to give human operator a real sensation of presence that enables him/her to perform teleoperation task dexterously with the feeling that they exist inside the slave robot in remote environment. By establishing dynamics model of a master slave robot force telepresence system in Cartesian frame, the bilateral control structure and control strategy were formulated systematically. The result of dynamics analysis shows that the operation force of operator is disturbed differently by the dynamics of master and slave arms under different control strategies. In force reflecting servo system, dynamics of both arms can be overcomed more efficiently.
