Agricultural engineering has become a high-tech field with highest worldwide relevance with respect to food, energy as well as landscape conservation. There is a strong need for innovations and new ideas to create solutions with ecological, economical and social relevance. The future applications of autonomous small size robots and robot swarms in agriculture will be a revolution in this field. However, whenever technology meets nature, considerable technical and non-technical challenges have to be solved. The International Field Robot Event, founded by Wageningen University (The Netherlands) in 2003, has stimulated the development of autonomous field robots and has become a major platform for innovations, interdisciplinary cooperation and information exchange. The Field Robot Event 2008 included the contest itself, the Field Robot Junior with about 30 school teams, a high-tech agricultural exhibition, the award ceremony "Germany - Land of Ideas: Selected Landmark", a scientific symposium and much more ! The proceedings and other information can be downloaded (see "Download").
