Item type:Publication, Access status: without files , Evaluating Magic Leap 2 controller tracking for sensor tool guidance in AR-based industrial inspectionsRigorous evaluation of commercial Augmented Reality (AR) hardware is crucial, yet public benchmarks for tool tracking on modern Head-Mounted Displays (HMDs) are limited. This paper addresses this gap by systematically assessing the Magic Leap 2 (ML2) controller’s tracking performance. Using a robotic arm for repeatable motion (EN ISO 9283) and an optical tracking system as ground truth, our protocol evaluates static and dynamic performance under various conditions, including realistic paths from a hydrogen leak inspection use case. The results provide a quantitative baseline of the ML2 controller’s accuracy and repeatability and present a robust, transferable evaluation methodology. The findings provide a basis to assess the controller’s suitability for the inspection use case and similar industrial sensor-based AR guidance tasks.Publicationtype: Conference Paper112 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , HyPLANT100 - Automatisierung der Produktion von Elektrolyseuren größer ein Gigawatt(2025-07-02); ; ; ; Um den mittel- bis langfristigen Wasserstoffbedarf in Deutschland, Europa und weltweit zu decken, müssen Produktions- und Planungsprozesse von Elektrolyseuren effizienter werden. Wasserstoff ist ein zentraler Bestandteil der Energiewende als emissionsfreier Energieträger und zur Speicherung erneuerbarer Energie. Derzeit ist die Herstellung großskaliger Elektrolyseure durch manuelle und zeitaufwendige Arbeitsschritte begrenzt, das führt zu hohen Kosten und begrenztem Durchsatz. Ziel des H2Giga-Projekts HyPLANT100 ist es daher, den Übergang zur automatisierten Serienfertigung zu erforschen und so die wirtschaftliche Bereitstellung von Elektrolyseuren für industrielle Anwendungen, wie die Stahl- oder Düngemittelproduktion, zu ermöglichen.Publicationtype: Conference Poster not in Proceedings80 39 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Industry 5.0 in aircraft production and MRO: challenges and opportunitiesGlobally interconnecting machines, processes, and resources driven by exploring and advancing new technologies defined Industry 4.0 (I4.0), resulting in, e.g., Cyber-Physical Production Systems (CPPS). The aircraft industry particularly struggled with transforming production and Maintenance, Repair, and Overhaul (MRO) processes, replacing humans with machines and automating as well as digitalizing significant parts of their value- and non-value-adding activities. However, in the face of current social and environmental challenges, future industries will need to shift from purely technology-driven to value-driven, working sustainably with resources, including human capital. Together, these approaches constitute the idea of Industry 5.0 (I5.0). On the one hand, the aviation industry faces the challenge that even I4.0 concepts and technologies are not yet fully exploited or implemented. On the other hand, due to the specific characteristics of aircraft production and MRO as well as the environmental impact of the product, a tremendous potential arises regarding placing human well-being back into the center of adding value and decreasing environmental footprint while building an industry that is resilient and fortified against disruptions of this era. In line with the I5.0 terminology, in this work, we outline the challenges and opportunities of integrating I5.0 principles into the aircraft production and MRO industries, focusing specifically on the scope of selected use cases.Publicationtype: Journal Article63 42 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Augmented reality authoring for efficient inspections in green aviation: evaluating accuracy and usabilityThis paper addresses the gap in AR-guided inspection by developing and evaluating an AR authoring tool tailored for green aviation. The tool aims to overcome the current limitations by assisting the inspector in the data acquisition process using hand-held sensors. The study introduces a sensor guidance prototype applicable to various inspection scenarios prone to human error. Usability assessments reveal positive feedback on real-time guidance and an intuitive interface, though challenges in tracking accuracy and managing complex trajectories are identified, particularly with the Microsoft HoloLens 2. Testing on the Magic Leap 2 (ML2) showed sufficient position accuracy of 1.39 mm, suitable for mobile authoring and tracking of trajectories. While results are promising, further optimization in tracking, user interface (UI), and real-world validation is needed.Publicationtype: Conference Paper23 18 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: with files , HyPLANT100 : industrialization from assembly to the construction site for gigawatt electrolysis(Multidisciplinary Digital Publishing Institute (MDPI), 2024-06); ; ; ; The global push for sustainable energy has heightened the demand for green hydrogen, which is crucial for decarbonizing heavy industry. However, current electrolysis plant capacities are insufficient. This research addresses the challenge through optimizing large-scale electrolysis construction via standardization, modularization, process optimization, and automation. This paper introduces H<sub>2</sub>Giga, a project for mass-producing electrolyzers, and HyPLANT100, investigating large-scale electrolysis plant structure and construction processes. Modularizing electrolyzers enhances production efficiency and scalability. The integration of AutomationML facilitates seamless information exchange. A digital twin concept enables simulations, optimizations, and error identification before assembly. While construction site automation provides advantages, tasks like connection technologies and handling cables, tubes, and hoses require pre-assembly. This study identifies key tasks suitable for automation and estimating required components. The Enapter Multicore electrolyzer serves as a case study, showcasing robotic technology for tube fittings. In conclusion, this research underscores the significance of standardization, modularization, and automation in boosting the electrolysis production capacity for green hydrogen, contributing to ongoing efforts in decarbonizing the industrial sector and advancing the global energy transition.Publicationtype: Journal Article32 409 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Leakage Inspection for the Scale-Up of Hydrogen Electrolyzers: A Case Study and Comparative Analysis of Technologies(2023-06); ; Since hydrogen is odorless, invisible and highly flammable, regular checks must be carried out to ensure the safe operation of large-scale H2-electrolyzer systems. Leakage tests are conducted during the assembly, the commissioning and the operation of the plant. Since many leakage tests have to be executed, efficient processes are required to reduce production and downtimes to enable a fast scale-up of electrolysis capacities. Therefore, Methods for leakage inspection are compared and technological implementations are discussed. This work contributes to the necessary analysis of requirements to derive research demands and solution concepts for large-scale electrolysis plants.Publicationtype: Conference Paper369 - Some of the metrics are blocked by yourconsent settings
