Which folder is the gmapping_demo.launch located at?
Another basic question on how to run the launch file. Is it
roslaunch gmapping_demo.launch
Hello @rojiroy,
As you can see in the instructions for Exercise 2.1, it asks you to execute the following command:
roslaunch turtlebot_navigation_gazebo gmapping_demo.launch
This already gives you the structure of the command you need to use in order to run the launch file and also, it tells you that the gmapping_demo.launch file is inside the turtlebot_navigation_gazebo package.
Best,
