“…The results are shown in Figure 9 as In these tests the focus was on movement within corridors. As stated in [16] such a setup is challenging for precise position monitoring for the UWB based positioning devices. The corridor was 2.5 m wide.…”

“…As reported, since it is a relatively new system, the accuracy and tag's battery life has to be further improved. The UWB technology needs a grid of anchors, whose proper placement is crucial for obtaining good positioning results [16]. The worst scenario for the UWB localization systems is a narrow corridor.…”

“…The worst scenario for the UWB localization systems is a narrow corridor. The estimated position of the robot from the UWB system is fluctuating in the order of tens of centimeters [16]. Remedy to this can be a denser anchor grid.…”

A completely new area of HoloLens usage is proposed. The Hololens is an augmented reality device, which provides the high precision location information. Such an information is normally used to accurately position holograms within the real space with respect to the viewer (user of HoloLens). The information is precise enough to use it for reporting the position for the purpose of autonomous driving. Several experiments have been executed in vast areas (20 m x 40 m) in order to find out the potential error coming from vibrations or other effects when moving the HoloLens. The results show that the technology can be used for spaces, which are previously known by the system - pre-scan of the space is needed. The big advantage of the system is its readiness for indoor positioning applications with no additional infrastructure needed, simultaneous localization and mapping, complex space mapping and reached precision. The disadvantage is mainly the costs.

There is a desire to move towards more flexible and automated factories. To enable this, we need to assure the safety of these dynamic factories. This safety assurance must be achieved in a manner that does not unnecessarily constrain the systems and thus negate the benefits of flexibility and automation. We previously developed a modular safety assurance approach, using safety contracts, as a way to achieve this. In this case study we show how this approach can be applied to Autonomous Guided Vehicles (AGV) operating as part of a dynamic factory and why it is necessary. We empirically evaluate commercial, indoor fog/edge localisation technology to provide geofencing for hazardous areas in a laboratory. The experiments determine how factors such as AGV speeds, tag transmission timings, control software and AGV capabilities affect the ability of the AGV to stop outside the hazardous areas. We describe how this approach could be used to create a safety case for the AGV operation.
