Lesson 5 concepts checking

I want to make sure that I understand what is going on conceptually at Unit 5. I am sure some of the service server concepts will be cleared in the next section but I want to know if I am understanding what I am doing throughout example 5. Is the following the correct way to think about coding done in this example. Please let me know if any mistakes.

hi @r.franklinismail,
i don´t see any mistakes here, you are pretty clear of what is happening. you can always have a look to all the launch files that are up. to avoid moving them to the catkin_ws folder (the only folder the IDE shows) you can have a a look with the rosed command: rosed name_of_package name_of_file
