The invention discloses a humanoid robot based on pneumatic muscles. According to the humanoid robot, human muscles are simulated by the pneumatic muscles to drive movement of shoulder joints, elbow joints, wrist joints, waist joints, hip joints, knee joints and ankle joints, so that the humanoid robot has a function of completely simulating human movement. The humanoid robot has the advantages ofcompact structure, cleanness and good anti-explosion performance, and can be applied to scientific research, teaching demonstration and medical diagnosis.

The invention discloses a humanoid upper limb based on pneumatic muscle. The pneumatic muscle simulates human muscle for driving a shoulder joint, an elbow joint and a wrist joint to move, and the function of completely simulating the motion of the upper limb of a person is achieved. The humanoid upper limb is composed of a rib, a vertebra, a shoulder blade, a humerus, a fibula, an ulna, a spherical hinge, the pneumatic muscle and a pneumatic muscle fixing plate; the pneumatic muscle of a humanoid upper limb girdle muscle drives the shoulder joint to retract and stretch, bend and extend, inwards rotate and outwards rotate; arm muscle drives the elbow joint to bend and extend, inwards rotate and outwards rotate, and meanwhile the arm muscle and the upper limb girdle muscle cooperatively drive the shoulder joint to inwards retract, outwards stretch, inwards rotate and outwards rotate; and forearm muscle drives the wrist joint to bend and extend and retract and stretch and drives the elbow joint to bend and extend, inwards rotate and outwards rotate. The humanoid upper limb is driven by the pneumatic muscle, has the beneficial effects of being compact in structure, clean and good in anti-explosion performance, and can be used for teaching demonstration, medicinal diagnosis and scientific research.

The invention relates to a humanoid robot system based on air cylinders and pneumatic muscles. Shoulder joints, elbow joints, wrist joints, fingers, waist joints, hip joints, knee joints, ankle jointsand toes of a humanoid robot are driven to move by using the air cylinders and the pneumatic muscles, and a function of completely simulating the movement of a person is achieved. The humanoid robotsystem is composed of linear cylinders, pneumatic rotary actuators, pneumatic muscles, bevel gears, vertebrae and connecting plates, wherein the plurality of linear cylinders drive the shoulder jointsto move, and the pneumatic rotary actuators are combined with the bevel gears to drive the elbow joints; the pneumatic muscles drive the wrist joints and the fingers, the plurality of pneumatic muscles drive the waist joints and the vertebrae, and the pneumatic rotary actuators are combined with parallelogram structures to drive lower limbs to move; and the shoulder joints, the elbow joints, thewrist joints, the waist joints, the hip joints, the knee joints and the ankle joints have 6 degrees of freedom, 1 degree of freedom, 2 degrees of freedom, 1 degree of freedom, 1 degree of freedom and2 degrees of freedom respectively. The humanoid robot system based on the air cylinders and the pneumatic muscles uses the air cylinders and the pneumatic muscles for driving, has the characteristicsof compact structure, good explosion-proof performance, multiple degrees of freedom and combination of rigidity and flexibility, and can be used for teaching and demonstration.

The invention discloses a multi-cylinder snake-like robot system based on pneumatic muscles. Multi-cylinder elements formed by the pneumatic muscles serve as executing elements to drive movement of joints, and a function of completely simulating snake movement is achieved. A multi-cylinder snake-like robot based on the pneumatic muscles is mainly composed of the pneumatic muscles, connection pieces and a fixed plate. The shrinking movement range of the multi-cylinder elements formed by the pneumatic muscles which are stacked in a staggered manner is far larger than that of a single pneumatic muscle of the equal length. Each single multi-cylinder element can go forwards, retreat and swing, and a combination of the multi-cylinder elements can go forwards, retreat and swing in many directions. The multi-cylinder snake-like robot system based on the pneumatic muscles is driven by the multi-cylinder elements formed by the pneumatic muscles, has the beneficial effects of being large in output force and good in cleaning and anti-explosion performance, and can be used for teaching demonstration, obstacle crossing and part grabbing.

The invention discloses a hydraulic-drive lower-limb mechanism with load bearing capability of a biped robot, which comprises two robot legs. The upper portion of each robot leg is connected with a robot steering mechanism, the robot steering mechanisms are arranged on the body of a robot, the lower portion of the each robot leg is connected with a robot foot, and each robot leg, each robot steering mechanism and each robot foot are driven hydraulically. A driving rotation freedom-degree rotation pair I utilizing the normal direction of the body of the robot as the axis, a lateral driving freedom-degree rotation pair II and a lateral driven freedom-degree rotation pair VI are arranged on one robot leg, one robot steering mechanism and one robot foot, and three front driving freedom degrees include the rotation pair II, the rotation pair IV and a rotation pair V. The hydraulic-drive lower-limb mechanism is simple in structure, capable of steering, easy to maintain and high in dynamic response capability and has obstacle detouring performance and the load bearing capability.

The invention discloses a simulated human lumbar vertebra system based on pneumatic muscles. Human muscles are simulated by the pneumatic muscles, movement of lumbar vertebrae is driven, and the system has the function of completely simulating human lumbar vertebra movement. The simulated human lumbar vertebrae mainly comprise a plurality of multifidus muscles, lesser psoas muscles, semispinalis muscles, vertebrae, rotator muscles, pelvises, rotator muscles, psoas muscles, quadratus lumborum muscles and pneumatic muscle fixing plates, and the muscles coordinately move to realize extension, retraction and circumduction of waist joints. The simulated human lumbar vertebra system is driven by the pneumatic muscles, has a compact structure, cleanness and a good explosion-proof performance andcan be used for teaching and demonstration.
