Development of a five degrees of freedom Master/Slave robot for tele-operated laparoscopic surgical operations

This paper presents the design of a five degrees of freedom surgical robot suitable for laparoscopic surgery. Robots based on this design must fulfil the constraints of manipulability for the operating surgeon and the possibility of use through Master/Slave system as a tele-operated haptic device. The proposed robot is able to perform a full human-like wrist motion and operates a surgical forceps. Screenshots of both Computer- Aided Design and simulation results of the robot workspace, as well as the manipulability model are shown in this paper.
