    Die Evolution einer Standardarchitektur für betriebliche Informationssysteme – Eine Fallstudie zur Wiederverwendung
    (Software Management 2002: Progress through Constancy, 2002) Echterhoff, Dirk; Grasmugg, Stefan; Mersch, Daniel; Mönckemeyer, Manfred; Spitta, Thorsten; Wrede, Sebastian
    The paper outlines the history of a standard architecture for small and medium sized administrative systems. It has been developped 1985 in the Schering AG / Berlin, and applied in several firms over more than 15 years. Some of the about 150 applications, developped and maintained by more than 100 programmers, are still in operation. In 1999 a revision of the architecture and a new implementation in JAVA was started. The latest version is a four-level-architecture for distributed systems with a browser as user interface. Aside architectural considerations we discuss some of our design and implementation experiences with JAVA.

    Plug, Plan and Produce as Enabler for Easy Workcell Setup and Collaborative Robot Programming in Smart Factories
    (KI - Künstliche Intelligenz: Vol. 33, No. 2, 2019) Wojtynek, Michael; Steil, Jochen Jakob; Wrede, Sebastian
    The transformation of today’s manufacturing lines into truly adaptive systems facilitating individualized mass production requires new approaches for the efficient integration, configuration and control of robotics and automation components. Recently, various types of Plug-and-Produce architectures were proposed that support the discovery, integration and configuration of field devices, automation equipment or industrial robots during commissioning or even operation of manufacturing systems. However, in many of these approaches, the configuration possibilities are limited, which is a particular problem if robots operate in dynamic environments with constrained workspaces and exchangeable automation components as typically required for flexible manufacturing processes. In this article, we introduce an extended Plug-and-Produce concept based on dynamic motion planning, co-simulation and a collaborative human-robot interaction scheme that facilitates the quick adaptation of robotics behaviors in the context of a modular production system. To confirm our hypothesis on the efficiency and usability of this concept, we carried out a feasibility study where participants performed a flexible workcell setup. The results indicate that the assistance and features for planning effectively support the users in tasks of different complexity and that a quick adaption is indeed possible. Based on our observations, we identify further research challenges in the context of Plug, Plan and Produce applied to smart manufacturing.

    The Cognitive Service Robotics Apartment
    (KI - Künstliche Intelligenz: Vol. 31, No. 3, 2017) Wrede, Sebastian; Leichsenring, Christian; Holthaus, Patrick; Hermann, Thomas; Wachsmuth, Sven; The CSRA Team
    The emergence of cognitive interaction technology offering intuitive and personalized support for humans in daily routines is essential for the success of future smart environments. Social robotics and ambient assisted living are well-established, active research fields but in the real world the number of smart environments that support humans efficiently on a daily basis is still rather low. We argue that research on ambient intelligence and human–robot interaction needs to be conducted in a strongly interdisciplinary process to facilitate seamless integration of assistance technologies into the users daily lives. With the cognitive service robotics apartment (CSRA), we are developing a novel kind of laboratory following this interdisciplinary approach. It combines a smart home with ambient intelligence functionalities with a cognitive social robot with advanced manipulation capabilities to explore the all day use of cognitive interaction technology for human assistance. This lab in conjunction with our development approach opens up new lines of inquiry and allows us to address new research questions in human–machine, human–agent and human–robot interaction
