Hi,

I just started with ROS Gazebo and already have working gazebo simulation with one robot which I can navigate and so on. However. I want to use two or more robots at the same time and thats where the problem starts. I already got both robots working and I can see both in the gzclient. But I got some other errors and I don't know how to solve them. So I used some advices from this post and they worked but I still got a lot of problems:

First, this is the tf tree, which is obviously wrong, but how can I connect odometry to the robots? frames.pdf

I also get this warning, which makes sense when I look at the frames.pdf file.

[ WARN] [1451572827.939870992, 1875.010000000]: MessageFilter [target=odom ]: Dropped 100.00% of messages so far. Please turn the [ros.gmapping.message_notifier] rosconsole logger to DEBUG for more information.

There are some other problems and I'm really new to this stuff, so I would appreciate some help.

In case you need more information, just ask and I can provide them.

Greetings Holyhawk
