摘要：
Parallel manipulators have the advantages of high stiffness and fine precision but the shortage of low workspace. A new type 3-DOF parallel manipulator with limbs of embedding structures is proposed. The peculiar topological structures make the mobile platform rotate continuously. The kinematics of the parallel manipulator is developed. Two kinematic parameters are decided to be optimized. The evaluation indexes about Jacobian's conditional number are deduced and the optimization model with constraint conditions is constructed. With the optimized kinematic parameters, a graph denotes the Jacobian's conditional number distributed in the workspace.
