As urban air quality is deteriorating and the haze weather appears frequently, people’s environmental awareness is strengthened day by day. There is a kind of green vehicles, which is different from traditional transport, is gradually integrated into people’s life. Compared with the electromobile, which have heavier and bulkier battery, but poorer overloading resistance motor, the new vehicle is fully using the latest technology and material. It’s self-balancing scooter.

The principle of self-balancing scooter is based on “homeostasis”, and that’s scooters’ self-balancing ability. To achieve the balance status, it mainly estimates the position of scooters by inside gyroscope and acceleration sensor, commands appropriately by precision high-speed calculation of smart chips, and drives the motors.

We assume that the overall center of gravity of rider and scooter’s vertical axis as the reference line. When the axis tilts forward, the electric scooters inside motor would generate the forward force to balance the rider and scooter’s forward dumping torque, and generate the acceleration which makes scooter move on. On the contrary, when the gyroscope finds the driver’s center of gravity backward tilting, it will also generate force backward to keep balance. Therefore, the rider just needs to change the angles of his body forward, backward, left and right, the self- balancing scooter will move forward, backward, turning left or right with the angles.

Flexible and comfortable driving mainly depends on the smart balancing chip in self-balancing scooter. The smart chip of Airwheel electric self-balancing scooter adopts aerospace attitude control theory, fuzzy software algorithm and gyroscope system to realize every directions’ self-balancing. It uses the world’s leading processor architecture to achieve a number of significant improvements. And it can centrally processing 1024 times floating-point computation per second, which is several times faster than common smart chip. When driving the self-balancing scooters, driver would have more comfortable driving experience. Moreover, drivers can quickly deal with the sudden trip, they won’t get hurt because of the delayed reaction of self-balancing scooter.
