A new structure of an 8-input 6-DOF parallel robot is introduced, and inverse kinematics is built up. According to the hormone modulation of neuroendocrine system and modulation model, this paper presents an intelligent controller that is suitable for the characteristics of an 8-input 6-DOF parallel robot with redundant drivers. Since it is difficult to find the exact dynamics model of the parallel robot, this paper makes use of the MimMechanics in MATLAB to build up the machine system model and then controls it with the proposed intelligent controller. The simulation result shows that the controller can control the movement of the robot effectively.
