Robot - Self-balancing Car Keyestudio KS0193
The Keyestudio balance car kit allows you to build a mini self-balancing car based on the Arduino development platform. The kit uses an UNO R3 as the core controller and a balance shield with a built-in MPU6050 sensor to detect the car body posture. Bluetooth connectivity enables wireless control using a mobile application.

The Bluetooth system is compatible with the Bluetooth XBee module for Android systems. The Bluetooth application supports key control mode and gravity control mode. Users can also adjust the balance angle and PID parameters through the application. All required assembly parts are included, along with detailed instructions for installation and debugging.
Working Principle
The self-balancing car maintains balance through dynamic balance control. The movement of the wheels driven by two DC motors keeps the car upright. The control system is divided into three main parts.
- Balance Control: Keeps the car upright by controlling wheel rotation.
- Speed Control: Controls movement speed by adjusting the car inclination through motor speed.
- Direction Control: Controls steering by adjusting the speed difference between the two motors.
