Part 2: Developing with ROS 2 – Python and C++

This second part focuses on writing code with ROS 2 and building scalable robotics applications. You already discovered the main concepts in Chapter 3 and got an intuition of how they work. You will now dive into each concept, one by one, with a real-life analogy, a deep dive into the code (with Python and C++), and extra challenges to help you practice.

This part contains the following chapters:

• Chapter 4, Writing and Building a ROS 2 Node
• Chapter 5, Topics – Sending and Receiving Messages between Nodes
• Chapter 6, Services – Client/Server Interaction between Nodes
• Chapter 7, Actions – When Services Are Not Enough
• Chapter 8, Parameters – Making Nodes More Dynamic
• Chapter 9, Launch Files – Starting All Your Nodes at Once
