Robots in the future are envisioned to become versatile helpers of man. Major challenges are to make them intelligent enough to enable exible and robust human-robot cooperation in shared workspaces and, moreover, to provide a simple, intuitive communication link between humans and robots. In Bielefeld, Germany, we follow a n i n terdisciplinary approach i n(More)
We present an assembly cell consisting of two cooperating robots and a variety of sensors. It offers a number of complex skills necessary for constructing aggregates from elements of a toy construction set. A high degree of flexibility was achieved because the skills were realised only through sensory feedback, not by resorting to fixtures or specialised(More)
This paper proposes a comprehensive approach on automatic optimisation of B-spline based neuro-fuzzy models. The underlying structure of a system decided by the displacements of the membership functions is an important factor for its generalisation ability and output accuracy. Therefore a genetic algorithm is introduced which is used to find a suitable(More)
Zusammenfassung In vielen technische Anwendungen sind adaptive Regler nützlich, die automatisch aus Trai-ningdaten konstruiert werden können, und deren aus dem Lernvorgang erzeugte Struktur einer Interpretation noch zugänglich ist. B-Spline Fuzzy Regler (BFRs) haben diese Eigenschaften, sind aber nur für Probleme niedriger Dimension geeignet. Um auch(More)
This paper presents the design and implementation of our English slot filling system. The objective of the slot filling task is to extract attribute values of the given entities. We developed a slot filling system which employs a combinative technique of dependency patterns matching and SVM-based supervision approach. Evaluation results show the strength(More)
