Hello, I am trying to programmatically get information about the pose of a PR2 in Gazebo. The examples on the wiki seem to be based upon command line using rosservice. Based upon the Publisher/Subscriber example on the ROS wiki I would imagine it would be something like:
rospy.Subscriber("gazebo/model_states", Pose, callback)
but when I try something similar to this Gazebo sends and error msg and breaks the connection. I would think it is just finding the right combination of topic and msg but I am having troubles figuring that out. Any help would be appreciate.
