Thank you very much, this solved my problem. But now the robot is easily stuck because of the obstacles. Which parameters can I change in the costmap and navigator configuration files to decrease the obstacle influence?

edit: I can only read your edit text and I see no comments. I used RVIZ to visualize the map as you said and I noticed two things: the turtlebot does a lot of circle because sometimes it isn't able to detect part of the map without obstacle: http://hpics.li/e0e94ff and it's not able to go between two obstacles (1m). The blue navigation line is good but not the green corrected line.

I used RVIZ to visualize the map as you said and I noticed two things: the turtlebot does a lot of circle because sometimes it isn't able to detect part of the map without obstacle: http://hpics.li/e0e94ff ( it's because of the bad laser quality) and it's not able to go between two obstacles (1m). The blue navigation line is good but not the green corrected line.line. I think it's because the costmap is too large for obstacles.

edit_2: Finally I changed of robot and I use an Hokuyo laser instead of the Kinect. All the nav2d packages are now working well and I'm able to use the default mapper node to build a map. Thank you very much for your answers.
