The introduction of wireless connectivity in industrial environments promises a rapid and cost-effective reconfiguration of machines and sensors. A key question in this context is: Which wireless technology is best suited for industrial settings? Many of the prevalent technologies, like WiFi and ZigBee, do not meet the requirements of certain industrial applications in terms of data rate, power consumption, and robustness. The lack of alternatives capable of achieving a good balance between these conflicting goals impedes progress. This is why researchers from the University of Klagenfurt, Airbus, and Lakeside Labs investigate the use of ultra-wideband (UWB) communications for wireless connectivity in industrial environments. Interestingly, UWB is commonly used for localization but is not yet an option for communications. Experiments with IEEE 802.15.4-2011 UWB devices were conducted in two industrial scenarios, namely a large-size aircraft assembly hangar and a medium-size production hall. These measurements are the first ones reported for off-the-shelf UWB devices in such setting and shed light on the potential of UWB to support emerging industrial applications. Jorge F. Schmidt, a senior researcher in …
By Pasquale Grippa, Evsen Yanmaz, Paul Ladinig, and Christian Bettstetter A transport system with passengers traveling between stations in periodically arriving cabins is considered. We propose and evaluate an access control algorithm that dynamically limits the number of passengers allowed to board the current cabin. Simulations of a ski resort lift with empirical passenger data suggests that such access control can balance out the average waiting times at different stations. The algorithm is robust against the estimation of passenger arrival and deboarding rates. A real-world test in a ski resort will follow. Status: This paper is currently under review. Preprints are provided on demand.
Wherever several clocks tick simultaneously, it is tricky to get them all to display precisely the same time. This can be a challenge for drone swarms that are airborne together. To tackle this problem, young scientist Agata Gniewek is developing new technologies.
What has travelled by road to reach us until now could be delivered by drones in the future. This has many advantages: Poor rural transport infrastructure or persistent congestion in large cities can be bypassed. In 2013, Amazon was among the first to announce the intention to deliver goods using small autonomous drones. But when might this technology truly become part of our daily lives? Drone researcher Pasquale Grippa provides some answers.
A novel boarding solution for cabin-based transport systems — e.g., ski lifts, cable cars, subways — is being discussed in industry and has already been implemented in the Austrian skiing resort Bad Gastein: In order to avoid long queues at succeeding boarding stations, a display in the boarding area tells the guests how many of them are allowed to enter the next cabin. This form of access control guarantees spare seats for passengers waiting at the middle station to go to the top station. The overall objective is to install fair access conditions at all stations which would automatically improve waiting time and comfort of passengers. We expect some system intelligence to compute the number of passengers to enter at each station and adapt this number in real time according to the varying passenger load. Compared to extensions or modifications of tracks, cabins, or cabin vehicles, access control would be an inexpensive solution to optimize systems. Researchers at the University of Klagenfurt and Lakeside Labs are currently assessing as to whether such access control can …
Austria establishes a test field for 5G mobile systems. It can be used by companies and research institutes to advance their prototypes and products. The concept was presented in a press conference at the ministry for transport, innovation, and technology this week.
A multidisciplinary team at the University of Klagenfurt is due to deliver initial insights on the efficient operation of a drone-based delivery network. Doctoral student Pasquale Grippa will present the results at the Robotics: Science and Systems event taking place at MIT this week.
An interdisciplinary workshop on self-organization and swarm intelligence in cyber physical systems was held at Lakeside Labs this week. Experts presented their work and discussed open issues in this exciting field.
An analysis of robotics conferences of the past four years shows that Austria has relatively low visibility. It also shows that expertise is distributed among a handful of universities.
Samira Hayat and I attended re:publica 2017 in Berlin. It was an exciting event not least because Samira gave a very personal talk about drones and their application in disaster response.
