Abstract (EN): This paper aims at showing the development of a positioning framework for autonomous guided vehicles (AGVs) and for materials handling systems working at an indoors quasi-structured environment. Because global positioning system (GPS) does not work indoors, other technologies are adopted to overcome the building radio signal weakening. Among several localization technologies evaluated, the radio frequency (RF) localization was found to be better suited than ultra-sonic (or sonar) and laser (or lidar) technologies, because it can adopt the AGV communications sub-system to build the localization hardware framework without great complexity increment. The triangulation setup based on RF technology is presented and the working principle is shown through an experimental result. RF localization appears to be accurate enough for hundreds of metres span indoors environments as it is supported by a triangulation method where several beacons exchange information with the AGVs through a wireless communications protocol.
