Build a real robot, and understand how it works.

Guides and courses for small robots you build on your desk: an ESP32 board, a distance sensor, motors and MicroPython. Every part comes with a shop that sells it, and every line of code is explained.

Most robot tutorials stop working the moment you build them.

A video skips a wire, a library has changed since it was recorded, or nobody says which battery to buy. You copy the steps, nothing moves, and there is no one to ask why.

Here, every step says why.

Each guide lists the exact parts, shows the wiring, explains the code line by line and the maths behind it. When something goes wrong, there is a troubleshooting chapter written for that robot.
