I am actually experimenting the gmapping package with the Turtlebot2. To create the map I am using a Hokuyo Laser and not the Kinect.
Everything works fine at the beginning, but at one point the Turtlebot has a localization problem. It's at the right place and one second later it moves several meters away in the map in rviz. Is seems that at the same time I have this error message : [ERROR] [1363969960.064180503]: Transform from base_link to odom failed And after that the map is not precise anymore.
Do you know what I can do to solve that ? How can this transform fail ? Why ?
Thanks for help, Caroline

should not! Did you experience that problems in cases other than map building?

I'm seeing the same problem. My setup is a Turtlebot1 (Create base) with Hokuyo but no Kinect, running Groovy. The symptoms I'm seeing are exactly the same on both map-building and navigating in a static map. Has anyone ever found a solution?

Yes, looks the same problem. I'll tackle it in shiloh's question
