NAiSE offers precise and reliable indoor navigation systems for Industry 4.0 applications. Our system enables autonomy for automated guided vehicles (AGV), robots as well as drones and people. It comprises the areas of tracking, data analysis and autonomous navigation. In the course of today's intralogistics AGVs are track-guided. Since the vehicles can only move on a predefined line, they are inflexible and not very efficient. Camera or laser technology, which is supposed to fix this problem, is very expensive and not reliable, since dynamic changes aren't always incorporated. With our indoor navigation system, we are able to navigate existing AGVs without any track guidance.
