The optical position guided vision (PGV) positioning system combines route tracking via colored tape and accurate positioning via Data Matrix codes in one device. It is an ideal solution for the reliable navigation of automated guided vehicles (AGVs), whether in material handling or automotive manufacturing applications. Due to its large reading window, PGV reliably detects colored route tracking tape and paint, even around tight curves or if tape is dirty. In addition, Data Matrix codes can be used for turning, accurately positioning an AGV, and other tasks. The safety absolute positioning system (safePGV) enables safe absolute positioning according to SIL 3/PL e for the first time with just a single sensor.
