The force feedback method for Master/Slave-Combined system

The master/slave-combined system has a simplified and miniaturized structure formed by combining the master and slave that are the teleoperation system. In a certain situation, the operator may want to feel the magnified/reduced admittance of the real environments. Or he may want to feel the specific predefined admittance of the virtual environments. This paper presents a force feedback control structure for the master/slave-combined system. Through the proposed control structure, the operator can feel the predefined admittance of the virtual environments in case of free motion, and the magnified/reduced admittance of real environments in case of contact situation. It is discussed how the elements of the admittance effect ...
