The principle of operation of the balance scooter is mainly the principle of aircraft balance, which is the automatic balance capability of the vehicle itself (electronic self-balance system). The built-in precision electronic gyroscope is used to judge the body's posture state, and after the appropriate instructions are calculated by the precision and high-speed central microprocessor , the motor is driven to achieve the effect of balance. Suppose we use the longitudinal axis of the overall center of gravity of the driver standing on the vehicle and the vehicle as the reference line. When this axis is tilted forward, the built-in electric motor in the body of the balance scooter will generate forward force. On the one hand, it balances the torque of the person and the scooter tilting forward, and on the other hand, it generates acceleration for the vehicle to move forward. The instrument found that when the driver’s center of gravity is tilted backward, the backward force will also be generated to achieve a balance effect. Therefore, as long as the driver changes the angle of his body to lean forward or backward, the balance scooter will move forward or backward according to the tilt direction, and the speed is proportional to the degree of the driver's body tilt. In principle, as long as the balance scooter has the correct power on and can maintain sufficient power to operate, the people on the vehicle do not have to worry about the possibility of tipping and falling, which is very different from vehicles such as scooters that generally need to be balanced by the driver.
