1. A multi-degree-of-freedom myoelectric artificial hand control system, comprising: a robotic hand, a robotic wrist, a stump receiving cavity, and a data processor, wherein the robotic hand and the stump receiving cavity are respectively mounted on two ends of the robotic wrist, a multi-channel myoelectric array electrode oversleeve is connected in the stump receiving cavity, and a control unit circuit board and a battery are connected to the multi-channel myoelectric array electrode oversleeve; the other end of the control unit circuit board is connected to the robotic hand and the robotic wrist; the data processor sends a surface electromyography signal collection instruction to the control unit circuit board so that the multi-channel myoelectric array electrode oversleeve collects the surface electromyography signal, and further receives data and processes the data, to generate a gesture prediction model,
wherein the robotic wrist comprises a bevel gear set mechanism, a belt pulley drive mechanism, a servo motor, and a wrist support frame; the bevel gear set mechanism is formed by four mutually engaged bevel gears arranged in a cross; two of the bevel gears positioned on a horizontal direction are mounted on the wrist support frame and separately connected to a transmission wheel; and the belt pulley drive mechanism is connected on the transmission wheel and is connected to the servo motor.
