2002 , Alegre, Fernando , Balch, Tucker , Berhault, Marc , Dellaert, Frank , Kaess, Michael , McGuire, Robert , Merrill, Ernest , Moshkina, Lilia , Ravichandran, Ram , Walker, Daniel

We describe our entry in the AAAI 2002 Urban Search and Rescue (USAR) competition, a marsupial team consisting of a larger wheeled robot and several small legged robots, carried around by the larger robot. This setup exploits complimentary strengths of each robot type in a challenging domain. We describe both the hardware and software architecture, and the on-board real-time mapping which forms the basis of accurate victim-localization crucial to the USAR domain. We also evaluate what challenges remain to be resolved in order to deploy search and rescue robots in realistic scenarios.
