John,
There are not problems with the location of the files, when I said map.png it was just to name the map with a generic name.
The thing is I can't make the gazebo work with that map. The map is the result of running the gmapping node, so it doesn't have the borders so delemetated, here I attach the file png file.
Any idea?? Do you think I am having this problem because the map is very big??
Thanks!!!
Nicolas

Nicolás,
>From your console output it looks like gazebo is looking for a file
/home/robot/src/autnavarc/ros-ana-pkg/wheelchair/fete_nico_mapa.png
but you mentioned you had saved map.png in
/home/robot/src/ros/stacks/simulator_gazebo/gazebo_worlds/Media/materials/textures
possibly double check your parameter "walls" containing walls.model and make sure the image tag contains only the file name, e.g.
fete_nico_mapa.png
and your grayscale map image file is located at
/home/robot/src/ros/stacks/simulator_gazebo/gazebo_worlds/Media/materials/textures/fete_nico_mapa.png

Hi John,
Thanks for answering, I ve tried with that you suggest me and also with executing in a new terminal "convert myfile.pgm myfile.png " but it is still giving this message:

Any idea?

Hi Nicolas,
I don't think gazebo can read pgm files. Try opening your map file in gimp, save it as a grayscale .png file. Place the file in a package that exports its prefix to gazebo_media_path (for example take a look at manifest.xml for gazebo_worlds), under a subdirectory [package_name]/Media/materials/texture/walls.png.
Then try your spawn again. Note that if the map is complicated, it might take gazebo's recursive rectangle wall builder more than 30 sec. to construct the model.

Hi Everybody!!!
I have made a map with gmapping, it is a file 'map.pgm'. Now I want to spawn its walls, for that I am using this launch file:
Where the file walls.model is
true
-8 -8 0
map.pgm
2
200
1
false
0.04
0 0 0
Gazebo/Rocky
The thing is that nothing happens in gazebo.
Any clue?? Does exist any documentation about how to spawn walls of a map??
Many thanks
Nicolas
