The rotor blades of a wind turbine are typically made from composite material, which withstands high forces during rotation. The huge dimensions of the rotor blades complicate the inspection processes in manufacturing. The automation of inspection processes has a great potential to increase the overall productivity and to create a consistent reliable database for each individual rotor blade. The focus of this paper is set on the process of rotor blade inspection automation by utilizing an autonomous mobile manipulator. The main innovations include a novel path planning strategy for zone-based navigation, which enables an intuitive right-hand or left-hand driving behavior in a shared human-robot workspace. In addition, we introduce a new method for surface orthogonal motion planning in connection with large-scale structures. An overall execution strategy controls the navigation and manipulation processes of the long-running inspection task. The implemented concepts are evaluated in simulation and applied in a real-use case including the tip of a rotor blade form.}, language = {en} } @article{KaemperDoepperEhrfeldetal.1998, author = {K{\"a}mper, Klaus-Peter and D{\"o}pper, J. and Ehrfeld, W. and Oberbeck, S.}, title = {A self-filling low-cost membrane micropump}, series = {Proceedings : an investigation of micro structures, sensors, actuators, machines and systems / sponsored by the IEEE Robotics and Automation Society in cooperation with the ASME Dynamic Systems and Control Division}, journal = {Proceedings : an investigation of micro structures, sensors, actuators, machines and systems / sponsored by the IEEE Robotics and Automation Society in cooperation with the ASME Dynamic Systems and Control Division}, publisher = {IEEE Service Center}, address = {Piscataway, NJ}, isbn = {078034412X}, pages = {432 -- 437}, year = {1998}, language = {en} } @inproceedings{EvansBraunUlmeretal.2022, author = {Evans, Benjamin and Braun, Sebastian and Ulmer, Jessica and Wollert, J{\"o}rg}, title = {AAS implementations - current problems and solutions}, series = {20th International Conference on Mechatronics - Mechatronika (ME)}, booktitle = {20th International Conference on Mechatronics - Mechatronika (ME)}, publisher = {IEEE}, isbn = {978-1-6654-1040-3}, doi = {10.1109/ME54704.2022.9982933}, pages = {6 Seiten}, year = {2022}, abstract = {The fourth industrial revolution presents a multitude of challenges for industries, one of which being the increased flexibility required of manufacturing lines as a result of increased consumer demand for individualised products.

The standardisation of an industry wide communications tool is a critical step in enabling inter-company operations. This paper discusses the current state of asset administration shells, the frameworks used to host them and their problems that need to be addressed. To tackle these issues, we propose an event-based server capable of drastically reducing response times between assets and asset administration shells and a multi-agent system used for the orchestration and deployment of the shells in the field.}, language = {en} } @inproceedings{BuschkuehleSchuermannWollert2009, author = {Buschk{\"u}hle, Peter and Sch{\"u}rmann, Volker and Wollert, J{\"o}rg}, title = {Abstraction of wireless communication by a convergence middleware in conjunction with a XML-configuration}, series = {Information technology and electrical engineering : devices and systems, materials and technologies for the future ; Ilmenau 07 - 10 September 2009 ; 54.

AR applications rarely consider users' preferences and do not provide customized spontaneous support under unknown situations.

Using this approach, users will have more freedom of choice during AR supported work, which leads to more efficient workflows. Error correction methods based on CAD models and predefined process data create individual support possibilities. The framework is implemented in the Industry 4.0 model factory at FH Aachen.}, language = {en} }
