Serial manipulator robot is one of the most advanced robots in the last decade. The demand for this type of robot leads the researchers to develop and improve the robot to increase its workspace, speed and to minimize the control complexity. This paper presents a novel robot configuration that combines a 6 DOF serial manipulator with a 3 DOF spherical parallel wrist. The serial manipulator is KUKA kr6 R900 type, which is a real industrial robot. At the same time, the parallel spherical wrist is 3-RRS type (Revolute- Revolute-Spherical Joint), which can support one translation movement in the Z-axis and two movements for orientations in the X-Y axis. This new model is designed to enhance the serial robot performance by increasing the position and orientations of the end-effector. The paper presents a complete conceptual design for the new robot configuration. Then, a kinematic model was derived, and a complete …
