Where I can find the launch files for hector_mapping after installtion

asked 2018-07-16 13:55:47 -0500 gravatar image

Hello everyone

I used sudo apt-get install ros-kinetic-hector-salm to generate a map using my rplidar

After running my rplidar successfully ( I can see the red points on the rviz from my lidar), after roslaunch hector_slam_launch tutorial.launch, the rviz opens up, but I don't see anything on the grid squares.

I'm trying to follow this tutorial here to edit my launch file so I can see the map

However, I'm not sure how to access my launch file as the tutorial mentioned

If you want to see the files from packages installed using apt then you can use rosbash commands. For example,

rospack find hector_slam_launch

will show you the path to the hector_slam package

rosls hector_slam_launch

will show you the contents of the hector_slam directory and

roscd hector_slam_launch

will change to the hector_slam directory. To see the contents of a file, use

rosed <package-name> <file-name>

so to see the contents of tutorial.launch you'd use

rosed hector_slam_launch tutorial.launch


Like I said in your previous question (#q297573) you don't edit the contents of another package. If you edit the contents of another package then you will lose those edits when the package is updated. If you create your own package instead, you're in control and won't lose those edits.

What you should do instead is copy the contents of tutorial.launch, save it to your own package, and modify that new file.

Ok, how do I open tutorial.launch to copy ? that what I'm stuck on gravatar image  ( 2018-07-16 14:53:30 -0500 )edit

It's listed on GitHub or navigate to it (using roscd as I showed you in the answer above) and open it.

I've updated my question to use the hector_slam_launch package and how to see the contents of a specific file.
