In 2004 I participated in the Field Robot Event in Wageningen, Netherlands, organized by the Field Robot Event Foundation and Wageningen University & Research. The goal of the event was to develop and demonstrate autonomous robots for agriculture. Sponsored by Rockingstone, I built RSFR-1, a robot that was able to navigate through a field and detect obstacles.
