Maybe more than a month earlier(It was 13 Dec 2020 noted on my scheduler), I've done this process successfully without any error. I've followed this Youtube video : https://www.youtube.com/watch?v=Qrtz0a7HaQ4

1st terminal : roscore 2nd terminal : roslaunch rplidar_ros rplidar_a3.launch 3rd terminal : roslaunch hector_slam_launch tutorial.launch I could find an error on 3rd terminal.

RLException: while processing /home/lbd_song/catkin_ws/src/hector_slam/hector_geotiff/launch/geotiff_mapper.launch:

I cannot find the directory as error says too. Please tell me how to fix this error. Thank you all the time.

Thank you for the report. The geotiff launch files were moved to a separate package, looks like I've missed a reference.

If I am not mistaken the "geotiff_mapper.launch" was moved from the "hector_geotiff" package to the "hector_geotiff_launch" package. So in order to resolve this error you have to go to your "tutorial.launch" file and change the line <include file="$(find hector_geotiff)/launch/geotiff_mapper.launch"> to <include file="$(find hector_geotiff_launch)/launch/geotiff_mapper.launch">

Should be fixed by 77b51a6.
