Autonomous Mapping in the Real Robots Rescue League

We describe the mapping system implemented by the IUB team in the Robocup Real Robot Rescue league. Although very simple, this represents the first and up to now unique system which produces a human readable map that can be directly given to the rescue team to quickly locate victims. We describe the sensors suite we used, how data are fused together, and the algorithm we implemented. Examples coming both from lab experience and real competition are provided.
