[Note] in this course I will often give you some “activities” for you to practice the subjects you’ve learned. This will start with an explanation of the challenge (this lesson) and then the video solution is in the next lesson. I encourage you to try to do the activities on your own and give it some time - that’s the best way you can make progress. If needed, come back to the previous lessons for a quick refresher. Of course, no worries if you can’t manage to solve the challenge the first time. If stuck for too long, watch the solution, and give it another try in a few days. [/Note]
Here’s a quick challenge for you. I have run some nodes with different names, and here is what I see with rqt_graph.

Your goal here is to get the same.
For that you’ll need to start 4 nodes, including those that you created before (the Python and the Cpp ones), and 2 nodes from the Turtlesim package.
No need to write any code here, you just have to start the nodes from your terminal, using the appropriate commands.
I will see you in the next lecture for the solution.
