By studying characteristics of planar mechanism of a 3RRR parallel robot, a forward kinematics problem is analyzed and solved numerically. At the same time, an analytical method is used to analyze and solve the inverse kinematics problem. With MATLAB for simulation and calculation, the results are built into a corresponding model by Pro/E for verification. Based on inverse kinematics, workspace of the 3RRR parallel mechanism is obtained by using a two-dimensional traversal search method. The conclusion shows that, when the rotation angle of moving platform is 0, the workspace reaches a maximum, and when the rotation angle is π/2, the workspace is a minimum. The method can reduce workload in solving the problem and improve computational efficiency.
