Towards a publish/subscribe control architecture for precision assembly with the data distribution service

Abstract

This paper presents a comprehensive overview of the Data Distribution Service standard (DDS) and describes its benefits for developing robust precision assembly applications. DDS is a platform-independent standard released by the Object Management Group (OMG) for data-centric publish-subscribe systems. It allows decoupled applications to transfer information, regardless of what architecture, programming language or operating system they use. The standard is particularly designed for real-time systems that need to control timing and memory resources, have low latency and high robustness requirements. As such, DDS has the potential to provide the communication infrastructure for next-generation precision assembly systems where a large number of independently controlled components need to communicate. To illustrate the benefits of DDS for precision assembly an example application is presented. © 2008 International Federation for Information Processing.
