These awesome pictures were made using several Roomba vacuum cleaners with differently colored LEDs attached. Quite a creative use for the robotic vacuum cleaner for sure.
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?
This is what the setup looks like.
Apparently this isn’t a new thing, however it is the first I’ve heard of it.
Besides looking really cool, these pictures illustrate quite well how robotic vacuum cleaners work. Essentially roaming around blindly until they hit something.
