ROS2 for Beginners: Robot Programming with C++ from Scratch

About this course

A complete, step-by-step introduction to Robot Operating System 2 (ROS2 Humble) using Modern C++ (rclcpp) designed for absolute beginners. Master the Linux terminal, C++ classes, smart pointers, ROS2 workspaces, nodes, publishers, subscribers, services, custom interfaces, parameters, launch files, TF2 transforms, 3D URDF/Xacro modeling, RViz2, and Gazebo simulation — building 5 progressive robotics projects culminating in an autonomous LiDAR obstacle-avoiding robot.

What you'll learn

• Navigate the Linux terminal, configure ~/.bashrc, and inspect live robot graphs with ROS2 CLI and rqt_graph
• Write clean Modern C++17 for robotics: classes, inheritance, std::shared_ptr, lambdas, and std::bind callbacks
• Create and compile ament_cmake C++ packages using colcon build, package.xml, and CMakeLists.txt
• Stream and process real-time sensor data using C++ Publishers, Subscribers, and Wall Timers

Prerequisites

• No prior robotics or ROS experience required. Every Linux and C++ concept is explained step by step for beginners!
