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?

Hi everyone!

I have a curious and simple problem with fake_localization. All my
navigaion stack runs great on my robot, with static map and amcl. But
when I replace amcl node by fake_localization with identical frame
settings, it reports
Waiting on transform from /base_link to /map to become available
before running costmap, tf error: Frame id /map does not exist!
which doesn't make any sense as it should work just the same. Map
server still starts fine.
Where might be the problem?

Thanks, Dominik
