TRILATERATION LOCALIZATION FOR MULTI-ROBOT TEAMS

摘要

Abstract. The ability of robots to quickly and accurately localize their neighbors is extremely important for robotic teams. Prior approaches typically rely either on global information provided by GPS, beacons and landmarks, or on complex local information provided by vision systems. In this paper we describe our trilatera-tion approach to multi-robot localization, which is fully distributed, inexpensive, and scalable. Our prior research focused on maintaining multi-robot formations indoors using trilateration. This paper pushes the limits of our trilateration tech-nology by testing formations of robots in an outdoor setting at larger inter-robot distances and higher speeds. 1
