Kinematics Analysis and Simulation for a Novel 5-DOF Serial-Parallel Robot

Parallel robots have higher strength stiffness, but the working space is smaller; tandem robots have larger working space, but the strength stiffness is smaller. With the advantages of both parallel mechanisms and serial mechanisms, the serial-parallel mechanism has more extensive application prospects. In this paper, a novel 5-DOF serial-parallel robot was introduced to realize the machining of complex curved surface. The structure characteristics and motion properties were analyzed and the degree of freedom was calculated by screw theory. The forward and inverse kinematic solution of robot were deduced by numerical and analytical method respectively. The 3D model of the robot was built with SolidWorks and imported into ADAMS for kinematics simulation. The results showed that the robot could realize the processing of complex surface, and could provide help for industrial production.
