2014-11-17 05:05:52 -0500 | asked a question | tf tree empty on PR2 Hi all, We have a PR2 and when starting it up (claim and start) under any account, the tf tree No frames show up, only tf_static is empty, or Do not show any frames. TF is running however, and I can publish new transforms, which will be shown, e.g. Normally (before and also in simulation) multiple frames should be advertised when starting the PR2. Any hint in what went wrong? Does it have to do with tf2? And where to start looking? system:

2013-01-25 01:29:03 -0500 | asked a question | Clean-up of rosparam after ending launch scripts Hi, I've a launch file that launches some PR2 controllers. I've another script that has to know which launch file has been launched. I tried creating a rosparam in my first launch file with the name of the controller. In my second script, I check the existence of the rosparam and whether the value corresponds with my desired file. But it seems that these rosparam's are not deleted when the first launch file is terminated, also when this rosparam is set in a node. My question is how to solve my problem, by either:
Thanks in advance! Nick |

2012-07-12 05:59:24 -0500 | commented question | Gazebo (Fuerte on Ubuntu 12.04) returns "Invalid arguments" My question relates (I think) to the one posted on the ROS-users mailinglist (unanswered) :"Remap does not work on gazebo_ros_prosilica" on 24/6/2012 |

2012-07-12 03:09:01 -0500 | asked a question | Gazebo (Fuerte on Ubuntu 12.04) returns "Invalid arguments" Dear all, I tried to run the KUKA youbot simulation in Gazebo, with code that worked just fine under Electric on Ubuntu 11.04. But now I get this very meaningful error 'invalid arguments' without further indication where to look. Gazebo is not coming up. The mentioned log files are empty or don't exist. The output shows also an attribute error, which Gazebo gives also when launching the PR2 or an empty world (which didn't pose a problem for those simulations). If I delete the remap statements out of the launch file, I get a new error (see below), although the remap statement looks fine. Anyone any idea? Did the syntax change? Thanks in advance!
