26, November 2015: In order to answer this question, gyroscope system in Airwheel self-balancing air board
must be analysed. Gyroscope is an apparatus composed of a wheel, which
spins inside of a frame (gimbal) and causes the balancing of the frame
in any direction or position. The principle of the gyroscope is that the
rotation axis of a rotating object is not changed when it is not
influenced by the external force. According to this theory, folks use it
to keep the direction, and the things that make it are called
gyroscope. Similar to the techniques of riding a bicycle, riders achieve
balance via slightly tilting sideways.
The faster the wheel turns, the less likely it is to have a force to maintain balance for electric scooters. The gyroscope should give it a force at work, so that it can quickly rotate, and can reach hundreds of thousands turns per minute in general, which can work a long time. Then, the direction of the shaft is read by a variety of methods, and the data signal is transmitted to the control system.
Acceleration and angular velocity of the two sensors are unable to obtain the accurate and stable posture, but these two sensors are complementary, namely, the acceleration sensor, will be better under static conditions. Gyro will be better under dynamic conditions. At this point, we need an algorithm to effectively combine these two signals to obtain accurate attitude information. So self-balancing electric scooter is achieved by the controller (intelligent chip), attitude sensor (gyroscope), and actuator (motor) three parts to achieve balance.
When the driver tilts the body, the attitude sensor produces corresponding attitude information. And after the controller is aware of this information, it will give order to the motor to rotate in the direction correspondingly. Attitude sensor measures the attitude of the vehicle in certain frequency, and output attitude to the controller. The controller adjusts the rotation direction and speed of the motor ceaselessly, to maintain a dynamic balance. This is how the Airwheel intelligent electric scooter realizes balance.
