Human body induction mechanical arm

The utility model provides a human body induction mechanical arm, comprising a mechanical arm set, a mechanical hand matched set and sensory assemblies. The mechanical arm matched set and the mechanical hand set adopt titanium alloy or aluminum alloy which is not easy to deform and are light. The sensory assembly comprises an angular velocity sensor and an accelerated speed sensor; the mechanical arm matched set comprises a humerus member, an ulna member, a carpal member and connection matched sets between joints, wherein the humerus member, the ulna member, the carpal member and the connection matched sets are connected successively in a movable manner; and the accelerated speed sensors are arranged at the humerus, the ulna and the carpal of the mechanical arm matched set, and the angular speed sensors are arranged at a shoulder joint, an elbow joint, a radiocarpal joint, a carpometacarpal joint and finger joints of the mechanical arm matched set. Through the separate assembling and disassembly of the mechanical arm and the mechanical hand, the human body induction mechanical arm improves the flexibility and the practicability, can finish the high accuracy task under harsh environment and has a wide application prospect in the fields of science, medicines and disaster relief.
