Abstract :
A novel 6-DOF parallel manipulator composed of two limited-DOF manipulators is proposed in this paper, the degree of freedom (DOF) of this manipulator is analyzed and the position kinematic modeling is established. The Jacobian matrix is derived by vector loops equations. The workspace is determined considering the interference check by the numerical method. Furthermore, the performance of the mechanism is evaluated according to dexterity criteria. In order to satisfy the different configuration requirements, the two reconfigurable structures are presented based on the presented 6-DOF parallel mechanism. The work provides basis for the development of the novel robotic manipulator.
