Design and evaluation of a bilateral master-slave hand system

A prototype bilateral master-slave hand system has been developed. Both the master and slave hands consist of three robot fingers using 3 degree-of-freedom (DOF) small manipulators each equipped with 3-axis force sensor to enable force feedback to the operator. In this paper, the master-slave hand system is described, and the system performance is evaluated based on the concept of the two-terminal pair network. Simulation results are reported which show that this master-slave hand system, using a bilateral control algorithm which was proposed previously, can realize almost ideal response in the low-frequency domain.<
