I don't know if you have already tried to do that, but I had a similar problem and I've just added a fixed transform in the launch file between the world frames of the two robots.

<node pkg="tf" type="static_transform_publisher" name="world_frames_connection" args="0 0 0 0 0 0 /turtlebot1/world /turtlebot2/world 100"/>

Then I obtained a single tree with two branches, one per robot.

Hope this helps

Thanks. Is this for real turtlebots? As I am trying to do it on actual turtlebots and not the stage simulator.

I am sorry, I am just working in simulation right now and moreover with a different kind of robots, but the problem was the same. I guess it should work also with the real ones.
