Revision history [back]

Hello dornhege, after your reply I started my computer again and it worked. But after shutting down the move-base node and starting it again (doing so a few times) the problem occured again. But it is not easy reproducible. My first impression is that there could something wrong in the gazebo plugin which produces this output

Dbg Plugin model name: mobile_base
[ INFO] [1390494712.717836162, 0.010000000]: Will publish tf. [mobile_base]
[ INFO] [1390494712.722853967, 0.010000000]: GazeboRosKobuki plugin ready to go!   [mobile_base]

I have to restart the gazebo simulation and in most cases navigation launches successfully.

I will try to track this problem in future. But up to this point it is annoying and it worked without any problems before the upgrade.
