ROS 2 in Embedded Systemen
(2022)
Das Robot Operating System in seiner zweiten Version (ROS 2) findet zunehmend Verwendung und das nicht nur in Robotern. Dieser Beitrag gibt einen Überblick über den Aufbau und die Funktion von ROS 2. Die wesentlichen Elemente werden vorgestellt, das Publish-Subscribe-Konzept, das der Kommunikation zugrunde liegt, wird erläutert. Die Anforderungen von ROS 2 an Hardware und Betriebssystem werden beleuchtet und es werden Betrachtungen zu dessen Echtzeitverhalten gemacht.
A trend from centralized to decentralized production is emerging in the manufacturing domain leading to new and innovative approaches for long-established production methods. A technology supporting this trend is Cloud Manufacturing, which adapts technologies and concepts known from cloud computing to the manufacturing domain. A core aspect of Cloud Manufacturing is representing knowledge about manufacturing, e.g., machine capabilities, in a suitable form. This knowledge representation should be flexible and adaptable so that it fits across various manufacturing domains, but, at the same time, should also be specific and exhaustive. We identify three core capabilities that such a platform has to support, i.e., the product, the process and the production.We propose representing this knowledge in semantically specified knowledge graphs, essentially creating three through features interconnected ontologies each representing a facet of manufacturing. Finally, we present an exemplary implementation of a Cloud Manufacturing platform using this representation and its advantages.
