In analyzing the kinematics of the hydraulic maipulator operating system, the generalized coordinates of the manipulator system was established. The rotating and moving joints were selected from the mechanism as joint variables. The generalized transformation matrices were worked out. The kinematic equation at the finger end of the manipulator was calculated, and the obverse solution for manipulator was obtained. The operating geometrical parameters and primary techno-index of the manipulator system are simulated. The simulation results showed that the manipulator operating system meets the working task requirements. The study provides a theoretical basis for optimizing the structural parameters. It verifies the feasibility that the manipulator can be used in an engineering equipment platform.
