Hi!! Another thing is that when I run my program I have this warnings:
[ WARN] [1292518318.364947187, 0.448000000]: No transmissions were specified in the robot description.

Maybe has something to do with the model of my robot:
Gazebo/GreyGazebo/BumpyMetal50.050.0100000000.01.0Gazebo/FishGazebo/GreyGazebo/Yellow50.050.0100000000.01.0Gazebo/Blue0.164064010.0 0.0 0.0true-1001000.0710.020.00.005true20.0base_scanbase_laser_linkGazebo/Red100base_link_right_wheel_jointbase_link_left_wheel_joint${caster_wheel_offset_y*2}${wheel_radius*2}5true100.0base_linkbase_pose_ground_truth0.01map25.7 25.7 00 0 0true1000.0
Any clue??, I am lost here, jajaj.

John,
I will try to attach all the info that I can, first of all the image shows you the problem with the orientation of the laser taking as a reference the map.
Here goes the code:
THIS IS MY EMPTY WORLD

THIS ARE THE LAUNCH FILE THAT i AM USING:
AND
WHERE THE WALL MODEL IS LIKE:

That all, I dont know where i can start to solve this!!!!
Thanks

Hi Nicolas,
It would help if you can post the commands you are using to run your simulation. Also, if you're trying to attach an image that is too large (>150KB) for the mailing list, you can convert it to a compressed format such as jpg or alternatively use one of the free online gallery hosting services.

Hi!!
I am simulating a robot with a laser in Gazebo and it works quite well, but there are times when there is a desalinate between the orientation of the robot and the map, I mean the border of the map doesn't match with the laser points. As actually I dont know to much of gazebo and I didnt find anywhere this error, now I am asking to the list. It must be a problem with the tf, but the weird thing is that I do not have always this problems, just some times, but when it appears it continue like this until I finish the program.
I would like to add an image for u to see, but each time I try to add image my msg is rejected.
Thanks in advanced
Nicolas
