What are the domestic and international EMC (electromagnetic compatibility) standards for lower limb rehabilitation robots?

Lower limb rehabilitation robots, used to assist patients in gait training, must meet GB 9706.1, YY 0505 (domestic), and IEC 60601-1-2 (international) EMC standards. They integrate multi-joint servo motor drives, high-precision force/position sensors, and a safe emergency stop system. The standards require that the accuracy and stability of force and position control remain undisturbed in the treatment room environment, ensuring smooth and safe training movements, preventing sudden torque changes or accidental emergency stop triggering due to electromagnetic interference, and protecting patient safety. Since the robot system is in close contact with the patient, electrical safety is as important as functional safety.
