I have a simple question, should I create a launch file in catkin\_ws/src/turtlebot3\_move?  
Because the description of Topics Quiz didn’t mention it.

Hi @a13e5c2ddf294571 ,

You should go with the files in the instructions only. Which course and unit are you in?

Did you get any validation about launch file in the quiz result? If so, could you attach a screenshot?

Regards

I suppose what you are doing is the ROS Basics Real Robot project. It’s **not** a Quiz.

By convention, you create launch files for launching your package, or you use `rosrun`, [whichever is more appropriate](https://get-help.robotigniteacademy.com/t/differences-between-rosrun-and-roslaunch/56) for your use case.

Your launch files should be in `catkin_ws/src/your_project/launch`.
