By listening to sound, vibration and noise, we can judge whether the robot is faulty.

This is because the vibration or noise generated when the equipment is running is a sign of some abnormal situations. Therefore, by listening to the sound, we can make a physical examination of some sports equipment and identify whether there is a fault.

The sound and vibration emitted by the equipment are very important information. Whether the equipment is running normally can be judged by sound and vibration, so the maintenance cost will be reduced by half and the service life will be doubled.
