Module 2: ROS 2 Basics Overview

Welcome to Module 2, where we dive into the Robot Operating System 2 (ROS 2), the foundational middleware for modern robotics development. This module will introduce you to the core concepts, architecture, and practical tools needed to build sophisticated robotic applications.

Learning Goals for Weeks 3-5​

By the end of this module, you will be able to:

  • Understand the ROS Graph: Grasp the fundamental components of ROS 2, including Nodes, Topics, Messages, Services, and Actions.
  • Set up a ROS 2 Workspace: Confidently create and manage your development environment for ROS 2 projects.
  • Develop Basic ROS 2 Nodes in Python: Write simple publisher and subscriber nodes to enable communication between robot components.
  • Differentiate between Topics and Services: Understand the appropriate use cases for streaming data versus request-response patterns in robotic systems.
  • Troubleshoot Common ROS 2 Issues: Gain skills in diagnosing and resolving typical problems encountered during development.

This module is crucial for anyone looking to develop robust, modular, and scalable robotic software.
