roslaunch pr2_empty_world.launch not working

edit

Hey guys,

I am attempting to see the OMPL in action, so I was folling part 6 of the MoveArmJointGoal tutorial.

When I attempt to roslaunch pr2_empty_world.launch gazebo briefly opens, then suddenly closes with some red text left in the console.

Here are the last few lines of the console output:

loading model xml from ros parameter

the owner gazebo server (pid=30032) is not running.

Is there anything else I need to do prior to launching? Here are the logs mentioned above:

• gazebo-2*.log
• base_hokuyo_node-15.log
• tilt_hokuyo_node-16.log
• camera_synchronizer_node-17.log
