ROS is a robot middleware that is used my many research institutions world-wide. Therefore, many state-of-the-art algorithms of mobile robotics are available in ROS and can be deployed very easily. As a basic robot platform we deploy a 1/10 RC cart that is wquipped with an Arduino micro-controller to control the servo motors, and an embedded PC that runs ROS. In two weeks, participants get to learn the basics of mobile robotics hands-on. We describe our teaching concepts and our curriculum and report on the learning success of our students.}, language = {en} } @inproceedings{FerreinSchifferKallweit2018, author = {Ferrein, Alexander and Schiffer, Stefan and Kallweit, Stephan}, title = {The ROSIN Education Concept - Fostering ROS Industrial-Related Robotics Education in Europe}, series = {ROBOT 2017: Third Iberian Robotics Conference}, booktitle = {ROBOT 2017: Third Iberian Robotics Conference}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-70836-2}, doi = {10.1007/978-3-319-70836-2_31}, pages = {370 -- 381}, year = {2018}, language = {en} } @article{FrankoDuKallweitetal.2020, author = {Franko, Josef and Du, Shengzhi and Kallweit, Stephan and Duelberg, Enno Sebastian and Engemann, Heiko}, title = {Design of a Multi-Robot System for Wind Turbine Maintenance}, series = {Energies}, volume = {13}, journal = {Energies}, number = {10}, publisher = {MDPI}, address = {Basel}, issn = {1996-1073}, doi = {10.3390/en13102552}, pages = {Article 2552}, year = {2020}, abstract = {The maintenance of wind turbines is of growing importance considering the transition to renewable energy. This paper presents a multi-robot-approach for automated wind turbine maintenance including a novel climbing robot. Currently, wind turbine maintenance remains a manual task, which is monotonous, dangerous, and also physically demanding due to the large scale of wind turbines. Technical climbers are required to work at significant heights, even in bad weather conditions. Furthermore, a skilled labor force with sufficient knowledge in repairing fiber composite material is rare. Autonomous mobile systems enable the digitization of the maintenance process. They can be designed for weather-independent operations. This work contributes to the development and experimental validation of a maintenance system consisting of multiple robotic platforms for a variety of tasks, such as wind turbine tower and rotor blade service. In this work, multicopters with vision and LiDAR sensors for global inspection are used to guide slower climbing robots. Light-weight magnetic climbers with surface contact were used to analyze structure parts with non-destructive inspection methods and to locally repair smaller defects. Localization was enabled by adapting odometry for conical-shaped surfaces considering additional navigation sensors. Magnets were suitable for steel towers to clamp onto the surface. A friction-based climbing ring robot (SMART— Scanning, Monitoring, Analyzing, Repair and Transportation) completed the set-up for higher payload. The maintenance period could be extended by using weather-proofed maintenance robots. The multi-robot-system was running the Robot Operating System (ROS). Additionally, first steps towards machine learning would enable maintenance staff to use pattern classification for fault diagnosis in order to operate safely from the ground in the future.}, language = {en} } @inproceedings{GregorioFatigatiKallweit2015, author = {Gregorio, Fabrizio de and Fatigati, Giovanni and Kallweit, Stephan}, title = {Tiltrotor airframe flow field characterization by SPIV}, series = {11th International Symposium on Partivle Image Velocimetry - PIV15 , Santa Barbara, California, Sept 14-16, 2015}, booktitle = {11th International Symposium on Partivle Image Velocimetry - PIV15 , Santa Barbara, California, Sept 14-16, 2015}, pages = {15 S.}, year = {2015}, language = {en} } @inproceedings{HartmannKallweitFeldusenetal.2012, author = {Hartmann, Axel and Kallweit, Stephan and Feldusen, Antje and Schr{\"o}der, Wolfgang}, title = {Detection of upstream propagating sound waves at buffet flow using high-speed PIV}, pages = {14 S. : graph.

Bis vor kurzem basierte eine erschwingliche Hardware meist auf Mikrocontrollern mit den entsprechenden Leistungseinschr{\"a}nkungen z.B. im Bereich der Bildverarbeitung. Die Wahrnehmung einer 3D-Umgebung und somit die M{\"o}glichkeit zur autonomen Navigation wurde mit relativ kostenintensiver Hardware, z.B. Stereo-Vision-Systemen und Laserscannern gel{\"o}st. Die zur Auswertung der Sensorik notwendige Rechenleistung stand - entweder aufgrund des Stromverbrauchs oder der Performance meist f{\"u}r mobile Plattformen (lokal) - nicht zur Verf{\"u}gung. Durch Einsatz von leistungsf{\"a}higen Prozessoren aus dem Bereich der Mobilger{\"a}te (Smartphones, Tablets) und neuartigen Sensoren des Consumer-Bereichs, wie der Kinect, k{\"o}nnen mobile Roboter kosteng{\"u}nstig f{\"u}r den Einsatz in der Lehre aufgebaut werden.}, subject = {Robotik}, language = {de} } @book{Kallweit1994, author = {Kallweit, Stephan}, title = {Untersuchungen zur Erstellung wissensbasierter Fehlerdiagnosesysteme f{\"u}r Kreiselpumpen}, pages = {271 S. : zahlr. graph.
