Change code in line 15 to array_cal[4] = {80, 80, 120, 110}; Then click Upload.
Observe the four servos to make sure they are in proper angle, then the servo calibration is
completed. You can do fine tuning with value changing of “1” each time, if there is a little
deviation.
Since the servo angles on legs and feet differ, the final calibrated angles (array_cal[4]) will
be different too. It will take multiple times of calibration, you should adjust in patience.
viii. Ultrasonic Connecting
Plug one end of the ultrasonic connecting cable into the ultrasonic module, and the other
to the servo control board.
