In order to reduce the weight of the metal robot,the big arm of the 6-DOF robot is taken as the research object,and combined the forming process of the three-dimensional braided carbon fiber composite material,a lightweight design method of the manipulator based on the CFRP/QT(carbon fiber reinforced polymer/castiron QT 500-7)hybrid structure is proposed to design the structure of the manipulator.Through the static analysis of the hybrid structure manipulator by the finite element analysis method,the final scheme of the hybrid structure of the mechanical arm is obtained under the requirements of strength and stiffness.At the same time,the dynamic simulation results show that the robot equipped with a 24％weight reduction hybrid structure manipulator has good motion performance,and the driving torque of the hybrid structure manipulator robot at the J1 joint after weight reduction is smaller.
