Introduction

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 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. However, 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 with powerful functions and small size. It is very suitable to be applied in STEAM education for its 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 dedicated to 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 as well as acrylic boards. Therefore, you can easily assemble a cool Mecanum wheel 4WD smart car by yourself.
The version of Python running on the BBC Micro: bit is called MicroPython, which will guide you to use software Mu to write MicroPython language for Micro:bit main board to control the Mecanum car. In this process, not only can you enhance your ability to make stuffs but also learn the skills of programming.
Python is one of the most popular programming languages especially in machine learning for its availability and accessibility have brought huge convenience. However, MicroPython is committed to reviving the Python programming language in microcontrollers and embedded systems.
This is a Python tutorial for 4WD Mecanum Robot Car. If you haven't learned the basic tutorial ( Makecode tutorial.pdf), please learn it first. The basic one is programmed using graphical blocks, which is accessible for you to understand and start.
For your convenience, code in Python has been provided in every project, as well as code programming steps and code explanation in details. Hope you can better understand them.
