You are cordially invited to join us for a seminar on robotics and intelligent systems by the two invited speakers, Dr. Ubbo Visser from University of Miami, US, and Dr. Gerald Steinbauer from Graz University of Technology, Graz, Austria. RoboCup Seminar on Robotics and Intelligent Systems Organised by Advanced Robotics and Intelligent Control Centre (ARICC), Singapore Polytechnic & RoboCup Singapore National Committee Venue: LT12D, Singapore Polytechnic
Speaker: Dr. Ubbo Visser Abstract Autonomous agents in real-time and dynamic adversarial environments offer numerous research challenges. Perception, localization, decision-making, communication, and locomotion are good examples. The novel modern sports simulator we will discuss some results that have been made throughout a ten years period of research in the area of autonomous soccer playing robots. We will explore the problem of enabling autonomous agents in finding the right passing point or in making a complex decision within a soccer game while dealing with time constrains, hostile opponents, and dynamic environments. We propose a framework for spatio-temporal real- time analysis of dynamic scenes. We introduce a knowledge processing pipeline ranging from relevance-driven compilation of a qualitative scene description to a knowledge-based detection of complex event and action sequences, conceived as a spatio-temporal pattern matching problem. We present experimental results from the RoboCup 3D soccer simulation that substantiates the online applicability of our approach under tournament conditions. We then take a closer look at the 'Official Bundesliga Manager', a complex real-time soccer simulator that is based on user-models from actual data (e.g. passing performance, scoring accuracy) of real soccer players from the German Bundesliga. The underlying hierarchical three-tier multiagent system consists of autonomous BDI agents that allow dynamic group structures (e.g. an emergent situation for a wing attack). The online game runs seamlessly in a web browser with a new and state-of-the-art 3D visualization engine. We will concentrate on the latest developments that include research results from a motion capturing lab and face generators to enhance the believability of the players and the users' visualization experience.
Dr. Ubbo Visser is currently a Research Associate Professor in the Department of Computer Science at the University of Miami. He received his Habilitation in Computer Science (qualification for Full Professor) from the University of Bremen in 2003, his PhD in Geoinformatics from University of Muenster in 1995, and his MSc in Landscape-ecology from University of Muenster in 1988. His research specialization is in artificial intelligence, more specifically on knowledge representation and reasoning. He is interested in the combination of symbolic and sub-symbolic technologies in the domain areas of "Semantic Web" and "Multiagent Systems (RoboCup, Games)". His focus in the Semantic Web area lies in the development of methods that combine terminological logics and spatio-temporal representation and reasoning techniques. The focus in the Multiagent Systems area lies in the development of techniques for agents that act in highly dynamic and real-time environments. He won several awards for research and development of innovative AI software (e.g. Best AI Award from the Society for Informatics (GI) in Germany) and is a co-founder of innovative software companies both in Europe and in the United States. --------------------------------------------------------------------------------------- Speaker: Dr. Gerald Steinbauer
In this talk it will be motivated how model-based reasoning can be used to increase the robustness of autonomous robots. In the first part it will be describe how control software for robots can be enhanced with automated diagnosis and repair capabilities. The presented approach uses consistency based reasoning and a model and on-line observations of the communication within the software modules. The enhanced software framework is able to automatically cope with crashes and deadlocks of software modules. In the second part a general framework is presented which is able to detect, localize and repair faults in the hardware of robots drives. The approach uses a general model of the kinematics of a drive to detect and localize faults. Furthermore, the same model is used to reconfigure the control of the drive in order to retain the maximum functionality of the drive. In the third part recent work is presented how model-based reasoning can be used to detect and maintain inconsistent beliefs of autonomous mobile robots.
Gerald Steinbauer received a M.Sc in Computer Engineering (Telematik) and a PhD in Computer Science in 2001 and 2006 from Graz University of Technology. He is currently assistant professor at the Institute for Software Technology at the Graz University of Technology and works on intelligent robust control of autonomous mobile robots. His research interests include autonomous mobile robots, sensor fusion, world modeling, robust robot control, cognitive robotics, model-based diagnosis and RoboCup. He built up several RoboCup team at Graz University of Technology and works currently as its coordinator. Furthermore, he coordinates the RoboCup activities in Austria and served as Gerneral Co-chair of RoboCup 2009 Graz.He is a member of the IEEE Robotics and Automation Society, the IEEE Computer Society and the Austrian Society for Artificial Intelligence. Moreover, he is founder and president of the Austrian RoboCup National Chapter. |
