Student Christian Schurch created this loop for a school project.

The mechanical engineering student created this loop using four toy train tracks and a FANUC M-2iA/3S robot owned by Lucerne University of Applied Sciences and Arts. The project is being featured in an exhibition at the Luga and Christian has already set a new challenge for himself with his next project by using three tracks instead of four.
