I noticed that in the ROS Basics in 5 Days course, Unit 6 discusses the following: “Example 5.5, where you had to perform calls to a service in order to delete an object in the simulation?” Can someone clarify what it is talking about in terms of deleting an object? The only reference to deleting an object in the previous unit is at the very end of unit 5, but I don’t remember any other part of unit 5 talking about this. Is there some kind of error in the content of the notebook? I noticed that some unit numbers in the solutions of unit 5 seemed disconnected and the discussion in unit 5 seems to have been recently updated but in some cases is a little hard to understand. Perhaps this section of ROS Basics needs some proof reading.
