[Abstract]:The software robot driven by pneumatic muscle has the advantages of light weight, high power density ratio and high safety of man-machine interaction. A flexible robot arm with variable stiffness composed of extensional and contraction pneumatic muscles is proposed, which can decouple position and stiffness. In this paper, the stiffness test of single pneumatic muscle with contraction and elongation is carried out, and the model of air pressure, displacement and stiffness of single pneumatic muscle is established by least square method. Based on the single aerodynamic muscle stiffness model, the arm stiffness model is established for the designed flexible arm. The experimental platform of arm stiffness testing is built. The experimental results show that the stiffness of the theoretical model and the experimental model are the same. The average relative error is 3.60 and the maximum relative error is 6.17.
