Hello, On the pr2 we couldn't access to the /tf topic.

When launching the robot with robot.launch, we can see that : [robot_state_publisher-4] process has died [pid 23074, exit code -11

( and we get a segmentation fault if we try to launch robot_state_publisher by ourselves)

We followed http://wiki.ros.org/robot_state_publi... to try to see where the problem comes from:

rosparam get robot_description

don't give any errors but

rosparam get robot_description_new

is not find. As the wiki is old we don't know wich one is supposed to be called.

The /tf was working properly some months ago : we were able to get the pr2 model in Rviz and to display the laser sensors (that need to be transformed in the relevant frame for display, in our understanding). One possible cause of the absence of /tf may be that we tried to update the pick and place demo (sudo apt-get install pr2-object-manipulation ; here is the related question on the mailing list : http://lists.willowgarage.com/piperma... ), which may have led to inconsistency between the updated dependancies and the rest of the system.

Do you have any idea on what can be the cause, and of course, how to fix the problem ?

I think this is an ABI breakage in one of the dependencies used by robot_state_publisher. I've usually seen it show up when a dependency was due to installing a new package, but robot_state_publisher wasn't updated.

I've usually fixed this by running a dist-upgrade to upgrade all of the ROS packages on the system:

sudo apt-get dist-upgrade
