Totally different from conventional rigid robot, bioinspired soft robot has characteristics of deformable body, flexibility, continuous changeability and high active adaptability. It has become a new evolution in robotics. In this context, a flexible pneumatic robotic actuator FPA was proposed to act as both driver and executor for soft robot configration. The structure, principle and mathematic model...
Service robot, bionic robot and agricultural robot must directly contact with organism, which requires high security and adaptability. Flexible pneumatic actuators and joints can meet this demand. A type of flexible pneumatic rotary joint is proposed in this paper, based on the flexible pneumatic actuator FPA. The rotation movement is realized by inflating and deflating the rotary joint chamber. According...
Based on flexible pneumatic actuator FPA, two new kinds of pneumatic rigid-flexible joints are proposed. Three bending joints and one side-sway joints are used for designing two kinds of 4-DOF robot fingers. When inflating the FPA of each joint of 4-DOF fingers with different compressed air pressure, the fingers can simulate human fingers and realize bending movement and side-sway movement. Then the...
In order to eliminate twisting deformation of the flexible pneumatic bending joint, a rigid chain component is designed for it. Compressed air is filled into the pneumatic bending joint, the deformation of rubber tube occurred near the grasping point, and then the force is outputted by the pneumatic bending joint. The characteristics of the output force of the pneumatic bending joint are analyzed...
