Master the Future of Robotics

You don't need any robotics experience to start here. If you've ever been curious about how robots are programmed but didn't know where to begin — this is your starting point.ROS2 Basics is a completely free course designed for absolute beginners. No prior Linux experience, no ROS background, and no robotics knowledge required. Just a computer, curiosity, and the willingness to type your first command in a terminal.In this course you'll go from a blank machine to a working ROS2 environment — step by step, at a comfortable pace. You'll learn what ROS2 actually is, why the robotics world relies on it, and how to set it up correctly so you're ready to build real things.

Whether you've always wanted to build robots or you're transitioning into robotics software development, this course is where your journey begins. No prior ROS experience needed — just curiosity and a willingness to build.This course is built with a "learn-by-doing" approach. You won't just learn theory; you'll get your hands dirty with practical tools and projects. We'll start with the absolute basics—what is a ROS 2 node, package, and workspace?—and quickly move into the core communication patterns that power all robotic systems.You will master the "big three" of ROS 2 communication:Topics (Publish/Subscribe): For continuous streams of data, like sensor readings.Services (Client/Server): For request/response interactions, like "move to this position."Parameters: For configuring your nodes from the outside.We'll use Turtlesim and RQT tools to visualize these concepts, giving you a clear, graphical understanding of what's happening under the hood.The real power of this course is learning to build applications in both C++ and Python. You will:Review essential Object-Oriented C++ concepts (classes, inheritance, binding) specifically for ROS 2.Build a complete "Chatter" publisher/subscriber application from scratch in C++.Re-build the exact same application in Python to compare workflows and understand the strengths of each language.You'll finish by building a complete obstacle avoidance system from scratch and deploying it on a TurtleBot3 in Gazebo simulation. Your robot will sense its environment, make decisions, and navigate autonomously

This course is your complete guide to robot modeling and simulation using ROS 2 and Gazebo. You'll start from the ground up — learning how to build a robot's structure using URDF and Xacro, then bring it to life inside a fully simulated environment. By the end, you'll have a mobile robot with working sensors (LiDAR and Camera), differential drive control, and a complete simulation setup ready for real-world testing.Who is this for: Robotics beginners and ROS 2 developers who want to build and simulate real mobile robots from scratch.
