Hi guys,

Currently I am using ROS Noetic and Ubuntu 20.04 with gmapping and I can manually move the robot to generate the map. however how can I achieve this automatically? Meaning I do not want to move the robot manually or click on 2d navigation to go to unknown area. I want to run the mapping and robot decide by itself where to go and generate the map. I have already checked and applied following methods however none was successful (some were not supported by ROS noetic and other failed to catkin_make). I am still trying to get them working but I was wonder if anyone has better or easier solution to this issue.

Thank you
