Hi Dominik, fake_localization is meant for use in a simulator that publishes
base_pose_ground_truth (http://www.ros.org/wiki/fake_localization).  So it
won't work on a robot out of the box.  You would need to start the
fake_localization node with base_pose_ground_truth remapped to a topic of
type nav_msgs/Odometry that is being published on your robot.  Is there a
reason you want to use fake_localization?
