Design of a novel serial and parallel force feedback master manipulator

This paper presents the design of a novel serial and parallel master manipulator. Firstly, the mechanism configuration of the master manipulator with a novel serial and parallel mechanism is given. Parallel mechanism uses 3-RUU type to achieve position control, and serial mechanism adopts triaxial concurrent mechanism to realize posture control. Then, the kinematics analysis of the master manipulator such as parallel mechanism inverse kinematics and forward kinematics, jacobian matrix and serial mechanism kinematics are given. Thirdly, the master manipulator workspace is analyzed, and the master manipulator static stiffness for the three points in the workspace is also analyzed. Finally, the force feedback simulation experiment is carried out to verify the parallel mechanism force feedback. It can be seen that this novel serial and parallel master manipulator meets the design requirements and future force feedback.
