Summary

In this introductory chapter, we cleared up some of the most common confusion points regarding ROS: its name, what it is and isn’t, when to use it, and why. You also learned more about the different ROS versions (ROS 1 and ROS 2), and you learned what kind of prerequisites you need to get started with ROS 2.

You should now have a better understanding of the big picture, and even if everything still seems a bit confusing, don’t worry too much—it will all make sense when you use the ROS 2 concepts and code with them.

Now, to be able to use ROS 2, we need to install it. This will be the focus of the next chapter and will help you get your environment 100% ready for ROS 2.
