It is now the time to explore ROS communication features.

At the end of this section you will be able to make your nodes communicate between each other, using ROS 2 Topics.

Here’s what you’ll do in this section:

• Understand what is a ROS 2 topic thanks to a real life analogy

• Experiment on Turtlesim

And finally, you’ll work on an activity to practice on everything you’ve seen until this point.
