Performing the role of a scientist, Benjamin Maus and Prokop Bartonicek’s kinetic machine Jller selects and sorts pebbles found on a 6 1/2 x 13 foot platform into a grid organized by geologic age. Without assistance, Jller analyzes the stones’ appearance to understand their correct placement, then transports them to the correct location.
All of the rocks for the project were extracted from a German river of the machine’s own name, pebbles that are either the result of erosion in the Alps or have been transported by glaciers. Because the history of this sample location within the river is known, it is a relatively straightforward process to assign each stone its geological age. To do this, Jller first analyzes an image of the stone it selects, extracting information like dominant color, color composition, lines, layers, patterns, grain, and surface texture. The machine then places the stones in alignment of age and type by sucking them into an industrial vacuum gripper and dropping them in the correct location within the grid.
The project is part of ongoing research in the field of industrial automation and historical geology, and was presented last December as a part of the exhibition “Ignorance” at Ex Post in Prague. The full video of the project can be seen below.
