The invention discloses a humanoid
shoulder joint system based on a
rope. A motor and the
rope are adopted to simulate muscles of a
human body to drive a
shoulder joint to move, and the function of completely simulating
human body shoulder joint movement is achieved. A humanoid shoulder joint is mainly composed of a shoulder blade, a
humerus, an
ulna, a supraspinatus, a teres minor, an infraspinatus, a deltoid, a latissimus dorsi, a triceps brachii, a
coracoid brachialis, a
biceps brachii, a motor and a
rope guider. The supraspinatus, the teres minor, the infraspinatus,the deltoid, the latissimus dorsi, the triceps brachii and the
coracoid brachialis jointly drive the
humerus to do bending, stretching, adduction, abduction and circumduction motion around the shoulder blade, and the tricepsbrachii and the
biceps brachii drive the
humerus to do bending, stretching, adduction, abduction and circumduction motion around the shoulder blade together with the supraspinatus, the teres minor, the infraspinatus, the deltoid, the latissimus dorsi, the triceps brachii and the
coracoid brachialis while driving the
ulna to do bending, stretching, adduction and abduction motion around the humerus. The motor and the rope are combined for drive, and the humanoid shoulder joint
system has the advantages of being compact in structure, good in flexibility and large in movement space, and can be used for teaching and exhibition.
