Abstract
The hardware system of two-wheeled balanced car designed in this paper uses STM32 as the master chip. MPU6050 is used as posture sensor of the system. Bluetooth communicates with the host computer to realize parameter setting, posture monitoring, data transmission and remote control for the balanced car. The car uses a geared motor as the power, and an infrared distance detecting module is arranged on the car body to realize obstacle avoidance function of the car. The software algorithm uses upright loop PD control, speed loop PI control, steering loop PID control, and three control links are parallel to control the speed of two wheels. After debugging and parameter setting, the self-balancing control of the balanced car is better realized, and the platform can expand more other functions.
