How to DIY a mini balance car on your own? This balance car kit is based on Arduino development platform. We mainly use REV4 as core and balance shield with built-in MPU-6050 as drive board to test the car body posture.
The balance shield comes with a Bluetooth interface, fully compatible with the Bluetooth XBee module (only compatible with Android system).
When connecting to Bluetooth, you can easily control the moving direction of balance car with Bluetooth APP, making a variety of unique postures.
To facilitate the operation control, Bluetooth APP has both key and gravity control modes.
Moreover, it adds the function of adjusting the balance angle and PID parameters as well, so you can perfectly adjust and control the balance car.
No need to worry how to play it. We can provide you with all assembly components, as well as the corresponding installation, debugging method and program.
The self-balancing car uses the power of the car body to maintain the relative balance, which is a process of dynamic balance.
The power to maintain the balance of the car comes from the movement of the wheels, driven by two DC motors.
The control of the car body can be divided into three control tasks as follows:
- 1. Balance Control: keep the car upright and balanced by controlling the forward and backward rotation of the car’s wheel.
- 2. Speed Control: realize the front and rear movement and speed control by controlling the inclination of the car. In fact, it is achieved finally by controlling the speed of the motor.
- 3. Direction Control: realize the steering control by controlling the rotational speed differences between the two motors of the car.
In this way, it is relatively simple to understand the three control tasks.
But in the final control process, it comes down to the control of a control quantity. So there will be coupling between the three tasks, which will interfere with each other.
The key is to control the car’s balance; the speed and direction control should be as smooth as possible.

Good article. The item took looooooong time to arrive, but I think the store did their job fast, and the problem was the shipment.
this product is one of the best robotics kits for education I ever ordered. Works perfectly, very good buildup of bare-bones tutorials which give a good insight into every detail of the components, and super fun to finally get to the end result. You can do the entire project in an evening, and the kit leaves plenty of room to expand. The Arduino balance shield is a nice board, combining an MPU6050, feedback and motor control in one nice package, neatly topped with all necessary cables. If you are not interested in the kit, the board itself is still worth considering. And last but not least, the service of Keyestudio rocks. After ruining one of the motors, they offered me a quick and cheap solution, so I can continue my exploration of this balancing kit. Thank you, Keyestudio :)
All right. All right. Good communication and fast shipping
Recommend! Description of comprehensive and very helpful.
Excellent robot, but here the program with the default parameters is not very well working-the robot falls.
