The Keyestudio balance car kit allows you to build a mini balance car based on the Arduino development platform. The kit uses an UNO R3 as the core and a balance shield with a built-in MPU-6050 to test the car's body posture. It features Bluetooth connectivity, which is compatible with the Bluetooth XBee module for Android systems. The Bluetooth connection allows control of the car's movement using a Bluetooth app that offers both key and gravity control modes. The app also supports adjusting the balance angle and PID parameters. The kit includes all necessary assembly components and detailed instructions for installation and debugging.

 

 

The self-balancing car maintains its balance through dynamic balance, using the movement of its wheels driven by two DC motors. The control tasks are divided into three main parts:

1. Balance Control: Keeps the car upright and balanced by controlling the wheel's rotation.
2. Speed Control: Manages the car's movement and speed by controlling its inclination, achieved by adjusting the motor speed.
3. Direction Control: Controls steering by adjusting the speed difference between the two motors.
