[cram-developers] cl-tf2 problems

[Jan Winkler]

Hey there,

I'm not sure about what exactly to start, but a tf2 topic has to be present on the current ROS master. Just grep for tf2 in rostopic list - it should show (I think) "/tf2_buffer_server", and "/tf2". Again, I'm not in front of a computer right now, so hopefully those are correct.

Did you start the ROS node? Because the action server is connected via a ROS init function.

So far from my side,
Cheers,
Jan

As TF2 works through action calls, do I need to start the action server by myself and how do I do this? As most of this changes have been made during the two weeks of Christmas and New Year's it's hard for me to track the changes in the repositories. Any help?
