[ros-users] URDF -> robot_state_publisher -> TF confusion

[pol.monso]

Well, everything seems correct and yet it does not try to connect. The
rosnode info robot_state_publisher output is the same as shown on
rxgraph when mouseovering on the node right?

Since it works with the tutorial urdf model, I'll try to isolate the problem.
