This paper describes an autonomous agent created for the Find Life on Mars competition held in Providence, RI. This competition closely parallels research currently being done here at the Colorado School of Mines in Urban Search and Rescue (USAR). Silver Bullet, an autonomous mobile robot, has been constructed under a 2 year NSF Research Experience for Undergraduates program for aiding rescue attempts in USAR situations. The AI approach was to integrate vision and navigation behaviors with affordances to search for signs of life. This paper reports on the results of the Find Life on Mars Competition and the implementation of intelligent search behaviors for a mobile robot.
