About Robotics Project Hub

Robotics Project Hub is a free learning platform for anyone who wants to understand how robots actually work. Instead of stopping at theory, every concept here is paired with an interactive simulator you can run directly in your browser—no hardware, no installs, and no sign-up.

Why we built it

Getting started in robotics is expensive and intimidating. Motors, sensors, controllers, and chassis add up fast, and a single wiring mistake can stall a beginner for days. We wanted a place where students and hobbyists could experiment with the ideas first—PID tuning, line following, obstacle avoidance, maze solving, sensor fusion, and inverse kinematics—so that when they do buy hardware, they already understand the system they are building.

What you'll find here

• Interactive simulators. Browser-native labs that let you change inputs and watch the robot's state respond in real time, so cause and effect stay visible.
• Step-by-step tutorials. Practical guides that connect the math to real Arduino, Raspberry Pi, ESP32, and ROS 2 builds, with code you can adapt.
• Downloadable diagrams. Clean, accurate wiring and control diagrams you can save and reference while you build.

Who it's for

The hub is written for beginners and students—from school science projects through final-year engineering—as well as self-taught makers and teachers looking for classroom-ready material. Everything is designed to be approachable without dumbing the engineering down.

How we keep it free

The content stays free to read. To cover hosting and keep new simulators and tutorials coming, the site is supported by advertising. You can read more about how that works in our privacy policy.
