Autonomous Systems – Digital Twin
The number of control and regulatory tasks taken over by embedded systems is huge, and is one of the reasons why autonomous systems are facing great challenges. In order to solve given tasks, embedded systems decide themselves at runtime with which other systems they will enter into networks, and in which they will only participate temporarily. As soon as systems dynamically extend their capabilities through the integration of third-party components, we speak of ecosystems. To be a part of these, autonomous systems need more than just data. The challenges lie in the combination of services. The solution are digital twins as a universally usable communication interface, which must work both across devices and across manufacturers. Digital twins must be able to describe themselves and the data and services offered, and must possess the ability to identify and select services required from other digital twins and use them to create their own networks. To realize this, there is an increasing need to employ task-oriented interfaces, which for instance define the goal of an action, but not how this action is to be executed.
Fraunhofer IESE is active in several areas to develop the concept of digital twins. Together with 14 other partners from the area of production technology, the institute is developing concepts and solutions in the context of the project BaSys 4.0 to realize digital twins as virtual middleware for digital production.
