The research adopts ESP32 MCU module as the main control,and the cost-effective motor driver chip DRV8833 and MPU6050 sensor are used as the hardware basis.Based on PID control model algorithm and inverted pendu-lum model,a small size,high integration,low cost,dual wheel wireless balancing car is designed.The experimental results show that the balancing car is simple in operation,good in performance,and can meet the needs of controllable motion and stable balance.
