Methodologies for building-wide testing exist, but their use is mostly limited to associated indoor localization competitions. The heterogeneous nature of ILS, their influences, and their applications pose various challenges for the design of a methodology that provides meaningful results. One reason is the lack of market transparency and stakeholders’ trust in the systems’ performance as a consequence of insufficient use of test and evaluation (T&E) methodologies. Measurements showed that this method improves the accuracy of the system, resulting in a more homogeneously distributed positioning error around a room.ĭespite their enormous potential, the use of indoor localization systems (ILS) remains seldom. Furthermore, the proposed safety system employs a novel method for post-processing ranging data. Dynamic measurements showed that the proposed safety system accurately mirrors the relative movement between the AGV and tag. The proposed safety system was mounted in an AGV designed by the company ASTI Mobile Robotics. This simplifies deployment of the solution and enables its use in dynamic environments. Instead, the AGV is equipped with sensors capable of locating the tag of a person or a mobile asset.
Unlike previous works based on UWB Real-Time Location Systems (RTLS), the proposed safety system does not require installing hardware on the plant’s infrastructure. This work presents a novel safety system for AGVs that is based on Ultra Wideband (UWB) technology. In order to guarantee safe operation, AGVs must be equipped with a safety system to stop their movement in presence of obstacles or humans in their path. Automated Guided Vehicles (AGV) are unmanned transport vehicles widely used in the industrial sector to substitute manned industrial trucks and conveyors.
