Jller is part of a research project on industrial automation and historical geology. The apparatus sorts pebbles from the German river Jller by their geologic age. The river carries pebbles that are the result of erosions in the Alps, and those from deeper rock layers once covered by glaciers. The machine uses computer vision to sort the stones by colors, lines, layers, grain and surface texture, and classifying them into age categories using a manually trained algorithm.
