This video shows the RFID technology-based exploration of a large robot team in Urban Search and Rescue environments (USAR). 
It consists of three parts: 
First, the local exploration approach (see paper) executed on 12 robots in an outdoor scenario simulated in the USARSim environment. Second, the same approach and robot team executed in an indoor (office like) environment. Both videos were taken by the judge during the finals of the Virtual Robot Competition at RoboCup 2006, and hence are a bit "shaky". During the competition, all 12 robots were running autonomously on a single Pentium 3GHz machine, and were able to explore up-to six times more space than any other team. During the exploration, the robots distribute RFID tags inn the environment (not shown on the video). Third, preliminary experiments on a real robot. This parts shows the autonomous exploration of the Zerg robot (counterpart to the simulated robot) distributing and recognizing RFID tags in the environment during exploration.
