ROS 2 Robotics: Modeling, Simulation, and Control

Robotics engineering requires a strong understanding of how physical machines are modeled, simulated, and controlled in software before they ever touch the real world. This course provides a clear, text-based path to mastering these essential skills using ROS 2, the industry standard for modern robotics software. By reading through this comprehensive guide, you will transition from understanding basic robotics concepts to designing custom robot models, running physics-based simulations, and implementing precise control loops. You will gain the confidence to develop software for autonomous mobile robots and robotic arms. What you'll learn: - Understand foundational ROS 2 concepts, including nodes, topics, services, and actions. - Create detailed 3D robot models using URDF (Unified Robot Description Format). - Configure realistic physics simulations using Gazebo to test your robot's behavior. - Implement robot control mechanisms using the modern ros2_control framework. - Apply coordinate transformations using TF2 to track robot links and sensors. - Practice writing basic ROS 2 publishers and subscribers to interact with your simulated robot. The course begins with essential robotics terminology and ROS 2 architecture before guiding you through hands-on modeling exercises. You will then progress to setting up physics environments and writing control code to bring your virtual robots to life. This course is designed for aspiring robotics engineers, software developers, and students who are new to ROS 2. No prior robotics experience is required, though a basic familiarity with programming concepts is helpful. Start reading today to build and simulate your first ROS 2 robot.
