The AAAI Robot Competition Reid Simmons Research Scientist Carnegie Mellon University For the past three years, AAAI has sponsored a mobile robot competition, the purpose of which is to showcase the state of the art in autonomous indoor mobile robots. This year, I organized the competition, which consisted of two events: office navigation (in corridors and offices) and office cleanup (finding and picking up trash on the floor). A dozen robots participated in the competition, from a five foot tall hovercraft to a foot-long robot, aptly named "Erratic". In this talk, I will present the rationale behind the design of the competition, describe (and illustrate) the how the robots performed and the various technologies employed, and explain what the results say about the state of autonomous mobile robots. I will also present some lessons learned about the difficulty of designing fair and adequate benchmark tasks.
