This paper proposes a method to correct operators haptic sense under time delay teleoperation system. In general, time delayed teleoperation system has problem in haptic sense transmission due to time delay difference between velocity and force at the operator side. Operator is likely to feel different haptic sense than remote object. This paper treats time delay as phase difference between force and velocity to treat such a problem. Correction force is generated based on phase characteristic in proposed method. Simulation and experiments are carried out to support the proposal.
