This invention relates to the fields of artificial intelligence and biomedical technology, specifically to a robotic automated patching method and system for peripheral nerve conduction detection, as follows: After the doctor selects the examination items on the electromyography instrument, the robot receives instructions and executes the operation; it extracts the patient's limb contour image through a binocular industrial camera system, and calls the nerve-electrode position mapping database to determine the relative positions of standard anatomical feature points; it uses probabilistic Hough transform to filter the lines corresponding to the joints, calculates the intersection points to obtain the feature point image coordinates, combines the relative positions to calculate the target patch position, and then solves the transformation matrix to obtain the three-dimensional coordinates of the robotic arm end; after determining that the electrode inventory is sufficient, it plans a path to grasp the electrodes, aligns and applies them with pressure, verifies the adhesion and contact resistance, and makes fine adjustments if they are unqualified or the impedance drifts; after completing the patching at multiple positioning points, it records the status to form a log, ensuring electrode stability before testing, achieving precise, stable and intelligent patching, reducing medical care intensity and improving diagnostic efficiency.
