An ER Haptic Master-Slave Robot System for the Minimally Invasive Surgery

摘要

In this research, a slave robot is proposed and integrated with an electrorheological (ER) haptic master for minimally invasive surgery (MIS). A novel mechanism of the slave robot with a gimbal joint is developed to realize 4-DOF motions. The proposed slave robot consists of two arms, gimbal joint and fixed bar. The haptic master can generate a repulsive force as well as position motion for the slave robot. The manufactured slave robot and haptic master are remotely connected with each other via TCP/IP communications. Both repulsive force and position tracking control are evaluated in experiment.
