Modular and scalable automation for field robots

2021 , Osten, Julia , Weyers, Catrin , Bregler, Kevin , Emter, Thomas , Petereit, Janko

This article describes a modular and scalable charging and navigation concept for electrified field robots and other agricultural machines. The concept consists of an underbody charging system on a trailer and a modular navigation box. The underlying conductive charging process is compared to other charging techniques. Charging time in relation to charging current and mean power consumption in field use is displayed. In the navigation box, data of various sensors are combined by means of multi-sensor fusion regarding the precise time of arrival. Time synchronization is achieved by a novel method for compensating the data latency jitter by employing Kalman based timestamp filtering. Furthermore, navigation functionalities, such as motion planning and mapping, are presented.

Situation responsive networking of mobile robots for disaster management

2014 , Kuntze, Helge-Björn , Frey, Christian W. , Emter, Thomas , Petereit, Janko , Tchouchenkov, Igor , Müller, Thomas , Tittel, Martin , Worst, Rainer , Pfeiffer, Kai , Walter, Moriz , Rademacher, Sven , Müller, Fabian

If a natural disaster like an earthquake or an accident in a chemical or nuclear plant hits a populated area, rescue teams have to get a quick overview of the situation in order to identify possible locations of victims, which need to be rescued, and dangerous locations, hich need to be secured. Rescue forces must operate quickly in order to save lives, and they often need to operate in dangerous enviroments. Hence, robot-supported systems are increasingly used to support and accelerate search operations. The objective of the SENEKA concept is the situation responsive networking of various robots and sensor systems used by first responders in order to make the search for victims and survivors more quick and efficient. SENEKA targets the integration of the robot-sensor network into the operation procedures of the rescue teams. The aim of this paper is to inform on the objectives and first research results of the ongoing joint research project SENEKA.

Deutsche Normungsroadmap Künstliche Intelligenz

2020 , Adler, R. , Kolomiichuk, Sergii , Hecker, Dirk , Lämmel, Philipp , Ma, Jackie , Marko, Angelina , Mock, Michael , Nagel, Tobias , Poretschkin, Maximilian , Rennoch, Axel , Röhler, Marcus , Ruf, Miriam , Schönhof, Raoul , Schneider, Martin A. , Tcholtchev, Nikolay , Ziehn, Jens , Böttinger, Konstantin , Jedlitschka, Andreas , Oala, Luis , Sperl, Philip , Wenzel, Markus , et al.

Die deutsche Normungsroadmap Künstliche Intelligenz (KI) verfolgt das Ziel, für die Normung Handlungsempfehlungen rund um KI zu geben, denn sie gilt in Deutschland und Europa in fast allen Branchen als eine der Schlüsseltechnologien für künftige Wettbewerbsfähigkeit. Die EU geht davon aus, dass die Wirtschaft in den kommenden Jahren mit Hilfe von KI stark wachsen wird. Umso wichtiger sind die Empfehlungen der Normungsroadmap, die die deutsche Wirtschaft und Wissenschaft im internationalen KI-Wettbewerb stärken, innovationsfreundliche Bedingungen schaffen und Vertrauen in die Technologie aufbauen sollen.

SENEKA - sensor network with mobile robots for disaster management

2012 , Kuntze, Helge-Björn , Frey, Christian W. , Tchouchenkov, Igor , Staehle, Barbara , Rome, Erich , Pfeiffer, Kai , Wenzel, Andreas , Wöllenstein, Jürgen

Developed societies have a high level of preparedness for natural or man-made disasters. But such incidents cannot be completely prevented, and when an incident like an earthquake or an accident in a chemical or nuclear plant hits a populated area, rescue teams need to be employed. In such situations it is a necessity for rescue teams to get a quick overview of the situation in order to identify possible locations of victims that need to be rescued and dangerous locations that need to be secured. Rescue forces must operate quickly in order to save lives, and they often need to operate in dangerous environments. Hence, robot-supported systems are increasingly used to support and accelerate search operations. The objective of the SENEKA concept is to network the various robots and sensor systems used by first responders in order to make the search for victims and survivors more quick and efficient. SENEKA targets the integration of the robot-sensor network into the operation procedures of the rescue teams. The aim of this paper is to inform on the goals and first research results of the ongoing joint research project SENEKA.

Kognitive Systeme und Robotik

2018 , Bauckhage, Christian , Bauernhansl, Thomas , Beyerer, Jürgen , Garcke, Jochen

Kognitive Systeme können komplexe Prozesse überwachen, analysieren und gewinnen daraus auch die Fähigkeit, in ungeplanten oder unbekannten Situationen richtig zu entscheiden. Fraunhofer-Experten setzen Verfahren des maschinellen Lernens ein, um neue kognitive Funktionen für Roboter und Automatisierungslösungen zu nutzen. Dazu statten sie Systeme mit Technologien aus, die von menschlichen Fähigkeiten inspiriert sind bzw. diese imitieren und optimieren. Der Bericht beschreibt diese Technologien, erläutert aktuelle Anwendungsbeispiele und entwirft Szenarien für zukünftige Anwendungsfelder.
