tf tutorial is displaying just one turtle instead of two
I am learning tf and doing the tf tutorials (py), In this tutorial:
http://wiki.ros.org/tf/Tutorials/Writ...
when I perform the command:
$ roslaunch learning_tf start_demo.launch
I am supposed to see two turtles, but I see only one. I've double checked the instructions and it seems all is correct. What I don't see is where the second turtle's starting position is indicated. Could it be that the second turtle is on top of the first one which is why I don't see it?
