Abstract
A new full-isotropic spherical three-DOF parallel mechanism was presented herein. This manipulator had decoupled rotational motion around x, y and z axes and employed only revolute joints. Based on the physical meaning of the cow vector of Jacobian matrix, the necessary and sufficient condition to synthesis full-isotropic parallel mechanism was obtained. Finally, an over-constraint spherical three-DOF parallel mechanism is obtained and a modified structure is also introduced to avoid the redundant constraints.
