Have you wondered to learn programming or have your own programming robot? Nowadays, programming has developed to a lower age group, and it will be a trend for everyone to be able to program thanks to the spread of simple graphical programming platforms, from micro:bit to Arduino and Raspberry Pi. Maybe you haven't heard of them before. It doesn't matter because with the help of this product and tutorial, you can easily install a multi-functional programming car and experience the fun of being a maker.

Micro:bit is a highly integrated microcontroller of powerful functions and small size. It is very suitable to be applied in STEAM education for it functions to make robots, wearable devices and electronic interactive games via the combination of code programming and graphical programming.

This Keyestudio 4WD Mecanum Robot Car is a smart DIY car specially designed for micro:bit. The smart car kit consists of a car body with extended functions, a PCB base plate with integrated motor drive sensors, 4 decelerating DC motors, Mecanum wheels, various modules and sensors and acrylic boards. Therefore, you can easily assemble a cool Mecanum wheel 4WD smart car by yourself, and then use Microsoft's online graphical programming platform Make Code to program the micro:bit control board to control the car. In the process, you can not only experience the fun of creation but enhance hands-on ability and learn programming skills as well.

MakeCode for micro:bit is the most widely used graphical programming environment on the micro:bit official website. It is based on the graphical programming environment developed by Microsoft's open source project MakeCode. This graphical programming can also be converted to code languages, python and javascript language. This combination makes learn programming easy. At the same time, MakeCode programming can be simulated or programmed for actual electronic components.

For your convenience, source code has been provided in every project, as well as code programming steps and code explanation in details. Hope you can better understand them.


This product is a smart car based on Micro:bit. It boasts multiply functions including ultrasonic sound following, line tracking, infrared control and Bluetooth control. It comes with a passive buzzer which is able to play music, 4 WS2812RGB LEDs to display different colors, 2 colorful lights to make direction lights for the car. This product uses two 18650 lithium batteries for power supply.

When installing and disassembling the battery, please pay attention to the positive and negative poles of the battery, and be sure not to reverse the them. By the way, the motor speed of this product is adjustable.

In order to provide you with better experience, corresponding documents about installation and test code are also provided.
