Today's mobile robot perception is insu?cient for acting goal-directedly in - constrained, dynamic everyday environments like a home, a factory, or a city. Subject to restrictions in bandwidth, computer power, and computation time, a robot has to react to a wealth of dynamically changing stimuli in such - vironments, requiring rapid, selective attention to decisive, action-relevant - formation of high current utility. Robust and general engineering methods for e?ectively and e?ciently coupling perception, action, and reasoning are unava- able. Interesting performance, if any, is currently only achieved by sophisticated robot programming exploiting domain features and specialties, which leaves - dinary users no chance of changing how the robot acts. The latter facts are high barriers for introducing, for example, service robots into human living or work environments. In order to overcome these barriers, additonal R&D e?orts are required. The European Commission is undert- ing a determined e?ort to fund related basic, inter-disciplinary research in a line of Strategic Objectives, including the Cognitive Systems calls in their 6th Framework Programme (FP6, [1]), and continuing in the 7th Framework P- gramme.

This book constitutes the thoroughly refereed proceedings of the 30th Annual German Conference on Artificial Intelligence, KI 2007, held in Osnabruck, Germany, September 10-13, 2007.

The 26 revised full papers presented together with 6 invited contributions and 21 posters were carefully reviewed and selected from 81 submissions. The papers are organized in topical sections on cognition and emotion, semantic Web, analogy, natural language, reasoning, ontologies, spatio-temporal reasoning, machine learning, spatial reasoning, robot learning, classical AI problems, and agents.

Much of AI research is about problem-solving strategies, and several techniques have been crystalized. One such technique is constraint satisfaction or reasoning based on relations. Constraint-based reasoning is used to solve a wide field of problems, and recently constraint techniques have been incorporated into logic programming languages, yielding a whole new field of research and application: constraint logic programming. Constraint satisfaction techniques have become part of almost all introductory books on AI. This monograph is about constraint satisfaction. It differs from others in that it presents all approaches under a common, generalizing view: dynamic constraints. This new way of viewing constraints provides new insights about the different approaches, and forms a very practical basis for teaching constraint-based reasoning. A uniform view of the constraint world is also a good basis for constraint research. This text is not intended to be a self-contained textbook on constraint-based reasoning, but rather a coherent text on an interesting view of the field.

Planning - formulating a course of action - and related fields like scheduling or reasoning about action have a long research tradition in artificial intelligence. However, there seems to have been a communications problem among European planners, with many of them unaware of good work done in neighboring countries. This volume contains ten papers presented at the European Workshop on Planning held in Sankt Augustin, Germany, March 1991. The purpose of the workshop was to provide a forum for presenting work in planning and related areas done by European researchers. The papers provide a snapshot of planning research at present being done in Europe. They describe work in the areas of plan generation, logical approaches to planning, planning under uncertainty, planning with time, and semantics of plans.

Mobile Roboter bewegen sich autonom im Raum. Die dafur notwendigen Berechnungen des Steuerungsprogramms beruhen wesentlich auf Sensordaten aus der Umgebung. Im Zentrum des Lehrbuchs stehen Algorithmen und Reprasentationen fur die Steuerung mobiler Roboter. Aufbauend auf Kapiteln zu Sensorik und Sensordatenverarbeitung werden alle zentralen nicht-mechanischen Aspekte der Fortbewegung behandelt. Das erste Lehrbuch in deutscher Sprache zum Thema eignet sich nicht nur fur das Bachelor-Studium, sondern auch zum Selbststudium und als Nachschlagewerk.
