AI Technical Summary
Existing soft robots suffer from the problem of being "more flexible than rigid," which makes it impossible to guarantee sufficient output force and pose accuracy during operation or target grasping tasks.
A variable stiffness pneumatic soft actuator was designed, including a pneumatic bending mechanism, a stiffness adjustment mechanism, and a base. The stiffness is changed by adjusting the deformation of the spring. Combined with a stroke multiplication mechanism consisting of a pneumatic hose, a radial limit ring, an annular groove, and a rope pulley system, the stiffness can be reversibly adjusted and precisely controlled.
The system achieves variable stiffness of the pneumatic soft actuator, improves output force and pose accuracy, and enhances adaptability and stability in different application scenarios.
