The paper gives an overview of the current state of the art in the radio frequency identification (RFID) technology. Aside from a brief introduction to the principles of the technology, a survey is given on major classes of RFID tags and readers, commonly used frequencies and identifier systems, current and envisaged fields of application, as well as(More)
The paper introduces a complete offline programming toolbox for remote laser welding (RLW) which provides a semi-automated method for computing close-to-optimal robot programs. A workflow is proposed for the complete planning process, and new models and algorithms are presented for solving the optimization problems related to each step of the workflow: the(More)
The paper discusses the technical background of the remote laser welding (RLW) technology, its novel opportunities and implications for planning processes. Our ultimate goal is to develop a complete off-line programming toolbox for RLW which can provide an automated method for computing close-to-optimal robot programs. We suggest a workflow for the complete(More)
Service robots serve and assist human beings sharing a common environment. Therefore fast responding and robust planners generating collision-free motions are required to guarantee a safe and convenient man-machine interaction. In most cases the working environment is partially known or perceived by a sensor system. To reduce planning time, this work(More)
This paper recapitulates the results of a long research of a family of AI methods—relying on, e. g., artificial neural networks and search techniques—for handling systems with high complexity, high number of parameters whose input or output nature is partly unknown, high number of dependencies, as well as uncertainty and incomplete measurement data. Aside(More)
The verification of embedded, safety-critical industrial systems is important, since a failure of these systems may have catastrophic consequences. Formal methods guarantee not only the correctness, but also the completeness of the analysis. However, even moderately complex industrial systems have state spaces so large that former analysis techniques could(More)
Recent trends in industrial production are marked by rapid changes in structures of collaboration or competition, as well as the spreading of customized production and more intricate customer demands regarding quality and visibility of delivery processes. All this calls for efficient means of tracking and tracing beyond company borders—a technological step(More)
