Multi-degree-of-freedom myoelectric prosthetic hand control system and use method thereof

Abstract

The invention discloses a multi-degree-of-freedom myoelectric prosthetic hand control system and a use method thereof. The system comprises a manipulator, a mechanical wrist, a stump receiving cavityand a data processor; the manipulator and the stump receiving cavity are installed at the two ends of the mechanical wrist respectively, a multi-channel myoelectric array electrode oversleeve, a control unit circuit board and a battery are connected in the stump receiving cavity, and the other end of the control unit circuit board is connected with the manipulator and the mechanical wrist. The using method of the system comprises the following steps that (S1) a user is allowed to wear the multi-channel myoelectric array electrode oversleeve, and the battery and the control unit circuit board are connected; (S2) the user is allowed to complete gestures, and surface electromyogram signals are collected and then the surface electromyogram signals are uploaded to the data processor; (S3) the data processor receives the surface electromyogram signals and inputs the surface electromyogram signals into a neural network algorithm to generate a gesture prediction model; and (S4) the user controls the multi-degree-of-freedom movement of the mechanical wrist and the manipulator. The system can recognize the continuous gestures and gesture strength and make multi-degree-of-freedom gestures.

Description

technical field [0001] The present invention relates to a prosthetic hand control system and its use method, more specifically, to a multi-freedom myoelectric prosthetic hand control system and its use method. Background technique [0002] Research on artificial prosthetics can be applied to many fields such as high-end medical equipment, biomechanical intelligent robots, hazardous environment exploration, disaster rescue equipment, national defense equipment, and assisting the disabled in rehabilitation engineering training. Its scientific and technological achievements can radiate, so it has Important strategic significance. So far, the humanoid robot hand structure based on single-degree-of-freedom has been very mature, but single-degree-of-freedom cannot fail to meet the flexibility requirements of simulated artificial hands, and there is no such thing as simultaneous recognition of artificial hand gestures and gestures. The strength algorithm limits the application of p...
