Learning paths

A path for every kind of learner

Paths are ordered routes through the library. Pick one by age, goal or kit, and your progress carries across all of them.

How every lesson works

Three tabs, so nothing stays theory

Each lesson explains the idea, shows it working, then hands you challenges to solve in a simulator.

Learn

Short explanations in plain words, with diagrams, worked numbers and a quick quiz.

Practice

Challenges from easy to hard, each with a hint and an answer, solved in the built-in simulator.

Examples

Circuits and code you can copy, run and change, from blinking LEDs to robot programs.

The library

Everything about robots

11 topics and 81 lessons, from “what is a robot?” to ROS 2 and computer vision.
