ROS Simplified — ROS 2 Tutorials

Welcome to the documentation home of ROS Simplified, a learner-driven publication dedicated to making ROS (Robot Operating System) concepts clear, practical, and accessible.

This repository is maintained under the ROS Simplified publication and hosts the full ROS 2 Tutorial for Beginners series — a step-by-step, hands-on guide that takes you from installing ROS 2 to building publisher-subscriber systems and inspecting them using the ROS 2 command line tools.

About This Series

The ROS 2 Tutorial for Beginners series is written for students, hobbyists, and engineers who want to actually understand ROS 2 rather than just copy-paste commands. Every part is hands-on: open a terminal alongside the article and follow along.

The series currently covers workspace and package setup, node creation (both function-based and class-based), rclpy.spin() and callbacks, workspace storage management, and the full publisher-subscriber communication model — including debugging it with ROS 2 CLI tools.
