Homogeneous master-slave robots have a wide application for tele-operation in dangerous environments, especially when the environment is so complicate that manual operation is needed. In this report, we present a tele-manipulation robot system with human arms as the master and an anthropomorphic dual-arm robot as the slave. The robot arm has 3 DOFs in shoulder, 2 DOFs in elbow, 2 DOFs in wrist, 2 joints in the thumb, and 3 joints in the other fingers. We adopt a wearable motion capture system to obtain the operator’s action command, and employ a motion-mapping algorithm based on unit dual quaternions (UDQs) to perform the joint-to-joint motionmapping task. We compute the expected/actual joints’ angle of the slave robot via the orientation data of the adjoining limbs of the master/slave arm, and successively execute the motion of every joint from the trunk to the distal joint of the robot arms. As a result, we can keep the slave arms possessing the similar configuration of the master arms in the whole course of telemanipulation. We validate our approach via experiment videos.
