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](https://hackaday.io/project/7284-oscar-omni-service-cooperative-assistant-robot/log/26164-first-foray-into-ros) 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
