Pneumatic and cable-driven hybrid artificial muscle

A pneumatic and cable-driven hybrid artificial muscle, characterized in comprising:

• a pneumatic actuator;
• a pneumatic pressure regulating assembly;
• and
• a cable actuation assembly;
• and
• wherein 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;
• the pneumatic actuator comprises an inner extending tube, an outer extending tube, a first sealing cap, and a second sealing cap;
• the inner extending tube is nested within the outer extending tube;
• each of the inner and outer extending tubes has a first end sealed with the first sealing cap and each of the inner and outer extending tubes has a second end sealed with the second sealing cap to form a closed air chamber;
• the inner extending tube has an inner cavity in connection with external atmosphere through a central through-hole on the second sealing cap;
• the pneumatic pressure regulating assembly is connected to the air chamber;
• and
• the cable of the cable drive assembly has one end fixedly connected to the first sealing cap.
