mapping node

Why can't the provided rosbag file be used for mapping? Is it because something is missing?

For mapping, you need the GT.csv (which is also provided in the documentation). Usually I drive the robot a bit differently when I am mapping (whether it's gmapping or our algos), like intentionally doing loop closures and getting more angles. You can try to use this rosbag for mapping. I personally didn't check how well it maps with this rosbag, but all topics (+ GT.csv) should be there.
