Thank you so much! With your help the new situation is:

Now everything works, but still it seems there is a problem with amcl, since it constantly changes (incorrectly) the transformation between /map and /odom.
The green lines are the inflated obstacles, so they are correct, I do not display obstacles because they are too heavy for rviz, but they works.
I tried to change amcl.launch in order to reduce the corrections, but the problem remains...
Here are the configuration files
