Problems Understanding the rxgraph results when using gmapping and navigation [closed]
Hi Ive been working on making a pioneer use gmapping and navigation and it has gone well and works, but when i look into the rxgraph some questions rise 1) why is there no /map topic publishing and why is move_base susbscribing to a /tf and not to a /map 2) Why is there so many /kinect_base_link nodes and what do these do? 3) why is there one node in a big double red circle?
I attached the rxgraph so any help would be great thanks
