1. 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.
