"Designers from Berlin creative firm Sonice Development created the Vertwalker, a roomba-looking, wall-climbing bot that paints a trail of color in its wake. At an installation in Jerusalem, the Vertwalker glided across a once-white wall in a nonsensical design, making seemingly random twists and turns along the way.  \nAs Fast Co. Design explains: \n\"The Vertwalker works autonomously with a fixed set of rules that make use of the internal sensors and keep it within a specified area on the wall. A pattern then emerges from these rules.\u201D\nIt\u2019s that unexpected pattern that creates the Vertwalker\u2019s wall art. While it looks like a well-done version of what a kid might do with a set of crayons, it\u2019s impressive to note just how the bot grips the wall.\nInside a small lip that lines the bot's outside hides a vacuum, which suctions the bot to the wall, but just enough so it can still freely glide.\nAlthough the Vertwalker makes it possible to tag the skyscrapers of the future with some drone-powered graffiti, that isn't the designers' ultimate goal. The team reportedly wants to have multiple Vertwalkers perform wall choreography \u2013- a drone dance of sorts. \nThe bot is currently on display in a London Gallery.\nImage: Vimeo, Sonice Development\n"^^<http://www.w3.org/2001/XMLSchema#string>
