it seems like .pgm and .yaml files on the wiki page don’t have all rooms mapped. I would suggest mapping rooms on your own to ensure the map will be exactly as you want.
Can I use the map and yaml file which their link found at the end of this page:
The map itself will work and ROSBot should be able to navigate with it. I can not guarantee you that this map will perfectly match this world. Also for more details on this world and its map, I would suggest consulting Willow Garage.
