Seaswarm: MIT’s Fleet of Oil Spill Cleaning Robots
Geeks for the Gulf, or what paper towels have to do with nanotechnology.
The Deepwater Horizon oil spill is easily the biggest environmental disaster of our time, bespeaking not only our capacity to do harm but also our inability to intercept the very harm we’ve inflicted. Since April 20, close to 200 million barrels of crude oil gushed into the Gulf, devastating the region’s ecosystem and economy. The world’s leading scientists, engineers and innovators failed to respond efficiently, offering no fix for nearly three months. Even though the leak was finally stopped on July 15, only 3% of the spill has been removed from the ocean and the remainder poses serious ecological risks, with no viable cleanup solution to date.
Enter seaswarm — a potentially gamechanging fleet of low-cost oil absorbing robots from MIT’s SENSEable City Lab.
The small, inexpensive, self-organizing skimmer operates autonomously and rolls out over the surface of the ocean, much like a paper towel soaking up the spill. It uses a breakthrough nanotechnology developed at MIT to separate the oil from the water and process it on-site. The nanofabric can be reused, enabling a constant cleanup process as the fleet of robots communicate and propel themselves across the ocean collecting oil.
The units are powered by solar cells and use a touch of biomimicry to mimic swarm behavior via GPS, ensuring even distribution across the spill site.
According to MIT, 5000* seaswarm robots operating continuously for a month will be enough to clean up the Deepwater Horizon spill. And as far as we’re concerned, a promise of this magnitude coming from the world’s most reputable innovation hub should be sending governments and philanthropists alike running for their checkbooks to make this happen, stat.
*UPDATE: The article originally stated 500, not 5000. We’ve fixed the typo thanks to commenter Helio Centric below, who kindly (!) pointed it out.

Facadeprinter: Graffiti Meets Paintball
Automating anti-establishment, or what street art has to do with disaster relief.
Much of street art revolves around the cult of the individual creator, creeping through the night to meticulously paint, stencil or tag a wall by hand. But can technology subvert this ethos? Facadeprinter is an inkjet printer in architectonical scale — a simple, software-controlled robot that shoots artwork from a distance of up to 12 meters, dot by dot, onto the target surface area. Think Banksy meets paintball meets ChalkBot — in other words, graffiti for geeks.
Designed by German duo Martin Fussenegger and Michael Sebastian, Facadeprinter can render artwork as large as 8 by 10 meters and, depending on the paint used, can produce permanent or temporary images. Besides the obvious uses in large-scale street art and advertising installations, the technology could have some interesting and rather useful applications in disaster relief, where the rapid printing process can enable quick and effective visual communication signaling shelter, food and water, danger zones, or medical aid.
Design is research. Driven by the desire to discover and understand. Above all a new design comes from a foreshadowing, which is looked into. Step by step this turns into an insight. If someone finally senses the result as being ‘beautiful’ or ‘new’, these are the many steps required of understanding, which produce a coherent whole. New aesthetics through new technology. Thus the Facadeprinter and the resulting rough printed appearance inseparably belong together.”
Here’s how it works: An integrated laser displays a bounding box of the artwork onto the wall, affixing its position. A paintball system converted into a printhead then shoots the color balls onto the wall, conveying the gelatine-encapsulated color balls to the marker where they are accelerated to a speed of 200km per hour. Upon contact with the wall, the balls burst, leaving dots 5 to 10 cm in diameter. The emptied out gelatine shells fall down to the ground where they can decompose naturally after rain without residue.
What makes Facadeprinter particularly interesting is that it’s an odd intersection of art and algorithm, raising questions of whether we can automate street art and preserve its message, and whether urban visual communication can serve as a design-driven humanitarian solution.
