Zero Point Calibration
For AIRBOT Play, if the LED is flashing in yellow, AIRBOT has detected loss of zero point reference.
In this case, long press the base button for 3 seconds, then the motor would be in free-drive status with large frictions. Drag the arm to the zero point position, and then press the base button again to finish the calibration.
After calibration, the LED would be breathing in green (if USB cable is connected), or breathing in white (if USB cable is not connected).
