Evaluierung der Lokalisierung von FTF durch robotergestützte RFID-Tests für einen Betrieb in unterschiedlichen Sicherheitsbereichen

Abstract

The flexible use of automated guided vehicles (AGVs) lends itself to their use in different safety areas with appropriately activated safety technology. Currently, AGVs only operate in one area for which they are appropriately equipped. In order to switch the safety technology between different safety areas, the vehicles must be safely localized in accordance with machine guidelines. Tests are being conducted to determine whether RFID technology can be reliably used for point of interest localization as an additional localization channel. For this purpose, on-metal RFID tags are positioned by a lightweight robot in front of an RFID reader and the distance and rotation are varied. Factors such as carrier plate material, thickness, width and grounding of the carrier plate are also considered. An influence of the carrier plate width on the readability of the tags could be determined. For combinations of distance and rotation, which are to be expected for the use of localization of AGVs, the reliable readability could be proven. The use of RFID is suitable for point of interest localization as a second channel for safe switching between safety areas.
