Abstract
This invention discloses a pneumatic and cable-driven hybrid artificial muscle, comprising pneumatic actuator, pneumatic pressure regulating assembly, and cable drive assembly. The pneumatic pressure regulating assembly is connected to the pneumatic actuator to regulate air pressure in the pneumatic actuator for controlling the pneumatic actuator to extend or contract. The cable actuation assembly comprises a cable fixedly connected to the pneumatic actuator for controlling the pneumatic actuator to contract. In this invention, the artificial muscle employs a dual pneumatic and cable actuation mechanism. By leveraging the inherent stiffness of the pneumatic actuator, it can provide substantial actuation force for joint movement. Simultaneously, the cable actuation assembly can provide significant pulling force, effectively ensuring safety in human-machine interaction and offering sufficient bidirectional aiding force to individuals with disabilities who use the artificial muscle as an aiding actuation device.
