About Robotics From Zero

Robotics From Zero exists because learning robotics shouldn't require a $5,000 robot arm or a PhD. Everything here is free, interactive, and built for people starting from scratch.

The project is built by engineers who remember what it was like to stare at a transform tree diagram and feel completely lost. We write the tutorials we wish we had when we started — specific, honest, and hands-on.

We focus on fundamentals that transfer across frameworks and hardware. Whether you end up using ROS2, a custom stack, or something that doesn't exist yet, the concepts here — coordinate frames, PID control, SLAM, path planning — will still apply.

Every lesson pairs theory with something you can interact with — a diagram you can manipulate, a quiz that gives instant feedback, or a code challenge in the playground. Reading about PID control is one thing. Watching your simulated robot overshoot a target because your gains are wrong is another.

We keep lessons short (5–12 minutes), avoid jargon walls, and never assume you already know something unless a previous lesson covered it. If you start at module 1, you have everything you need.
