Part of a "Roomba Art" picture series produced by Tobias Baumgartner, Marcus Brandenburger, Tom Kamphans, Alexander Kroeller, and Christiane Schmidt of the IBR Algorithm Group and Braunschweig University of Technology.We had a swarm of seven Roombas, each with a differently colored LED on top. The roombas are operating at the same time -- can you spot the collisions?
