[0002] Balance car, also known as somatosensory car, thinking car, camera car, etc., mainly includes one-wheeled and two-wheeled types. Its working principle is mainly to achieve balance by using a principle called dynamic stability. It uses the gyroscope and acceleration sensor inside the car body to monitor the changes in the center of gravity of the car body at all times, and uses the servo control system to accurately drive the motor to make corresponding adjustments to maintain the balance of the system. It is a new type of green and environmentally friendly product used by modern people as a means of transportation and leisure and entertainment. With the strengthening of people's environmental awareness, the use of electric vehicles has become popular. At the same time, after a lot of research by scientists, a new two-wheeled electric balance car has been developed. The two-wheeled electric balance car is a new type of transportation.
