Hi guys,

I am going through the tf tutorials (http://www.ros.org/wiki/tf/Tutorials) and I have followed the instructions carefully. After I rosmake and then roslaunch the start_demo.launch I get the following error repeatedly:

Frame id /turtle2 does not exist! Frames (1): Frame id /turtle2 does not exist! Frames (1): Frame id /turtle2 does not exist! Frames (1): Frame id /turtle2 does not exist! Frames (1):

and so on.....

I am using ros fuerte and ubuntu 12.04. Any ideas of how get rid of this error?

Thanks and best regards,

Khalid

Hi Khalid,

can you please provide some more details? Exactly which of the tutorials fails? Is it this one: (http://www.ros.org/wiki/tf/Tutorials/Writing%20a%20tf%20listener%20%28C%2B%2B%29)?. What does your tf tree look like when you run "rosrun tf view_frames"?

Thanks for your reply, The error was gone the next day, I did not change anything, just shut down my computer. However, I am facing another problem which I have posted in a new thread. The second turtle continuously rotates even if the first turtle is not moving.
