Disney rendered its new animated film on a 55,000-core supercomputer
Disney's upcoming animated film Big Hero 6, about a boy and his soft robot (and a gang of super-powered friends), is perhaps the largest big-budget mash-up you'll ever see. Every aspect of the film's production represents a virtual collision of worlds. The story, something co-director Don Hall calls "one of the more obscure titles in the Marvel universe," has been completely re-imagined for parent company Disney. Then, there's the city of San Fransokyo it's set in -- an obvious marriage of two of the most tech-centric cities in the world. And, of course, there's the real-world technology that not only takes center stage as the basis for characters in the film, but also powered the onscreen visuals. It's undoubtedly a herculean effort from Walt Disney Animation Studios, and one that's likely to go unnoticed by audiences.
Disney uses adorable little robots to illustrate big ideas
Disney Research has had some neat ideas in the past (capacitive touch feedback for plants, as an example), but the lab's amped up the cute factor lately. Its newest project? Getting tiny, LED-adorned robots to illustrate things such as The Big Bang. Like a good deal of Mickey's science projects, the experiment, dubbed "Pixelbots," is based around interactivity. The 2-inch swarm bots use magnetic wheels to move about on vertical surfaces. Meanwhile, an algorithm ensures that they won't hit one another and RGB diodes keep the robots looking pretty. Individual units can even be plucked out of formation and the pack will intelligently work to fix the gaps and reform the original shape.
Swarm robots perform classical 'scores' inside Georgia Tech's GritsLab (video)
The folks at the Georgia Robotics and InTelligent Systems (Grits) Lab at Georgia Tech have been hard at work for some time now researching swarm robots. A portion of said work deals with tasks that require a group of hi-tech gadgets to individually reach a location and a specific time -- much like the mobile landing platform that we saw last year. The group is given a "score" and must determine how many of the Khepera robots are needed to meet the goal, assigning specific roles and determining the shortest route to hitting their targets. One particular demo that we saw involved the swarm bots playing a projected piano of sorts to perform a short snippet of Beethoven's "Fur Elise" -- internal cameras, special "hats" and cameras mounted around the room lend a hand in carrying out the assigned duties. Musical performance is just one of the projects underway in the GritsLab. A real-world scenario involves the use of swarm robots for convoy cover. Using Parrot AR.Drones alongside the diminutive machines that we saw in action, researchers are looking at ways in which UAVs can be deployed to investigate and eliminate threats to convoys on the ground. This allows for the convoy to take an alternate route if needed while remaining under the watch of at least one UAV. For a look at the aforementioned classically scored action, jump down past the break to take a gander.
Khepera swarm robots learn to build a mobile quadrocopter landing platform (video)
Last we saw the Khepera swarm robots from the Georgia Robotics and Intelligent Systems lab, they were just beginning to learn how move in formation and spell out "GRITS" on the floor. Well, these bots are growing up fast. The lab's latest video shows a group of four of the robots following a leader, and arranging themselves to form a mobile landing platform for a hovering quadrocopter -- a feat they manage to make seem easy. What will they think of next? We're a little scared to ask.
Harvard's Kilobot project does swarm robots on the cheap (video)
We've certainly seen plenty of swarm robots before, but few of those are cheap enough to let you easily build something that can truly be called a "swarm." These so-called Kilobots developed by Harvard's Self-organizing Systems Research Group, however, can apparently built for just $14 apiece, and can each be assembled in just five minutes to boot. Despite that low cost, the bots are still capable of plenty of swarm-like behaviors, including the ability to follow the leader, disperse in an environment, put on a synchronized LED light show.

MIT Seaswarm autonomous robots coming soon to an oil spill near you (video)
Think of it as an autonomous, swarming, photovoltaic legion of seagoing Roombas (or don't, if you're easily upset). The Seaswarm project at MIT takes a thin, hydrophobic material and drags it behind a robot outfitted with GPS and WiFi for determining its location and communicating within a swarm. When deployed, the group finds the outer edges of an oil spill, and works its way into the center, coordinating the cleanup with minimal human interference. The material itself can take on twenty times its weight in oil. And yes, the whole thing is re-usable. According to researchers, 5,000 of these relatively low cost devices could have cleaned up the BP oil disaster in a month -- which is more than we can say for Kevin Costner! See it in action after the break.
Swiss lab builds lightweight, tree-perching glider robot, swarms to follow
Last we heard from Mirko Kovac of the Switzerland-based EPFL Laboratory of Intelligent Systems, he was setting a robot high-jump record with his grasshopper-inspired bot. Now he's back with what might be an even more impressive robot -- a 4.6 gram glider that can fly headfirst into any surface, perch itself, and then detach on command. The idea there being that the gliders could be outfitted with sensors and deployed en masse in difficult to reach areas -- Kovac gives the example of a swarm equipped with heat-sensors that could attach themselves to trees and monitor for forest fires. What's more, he says that the same perching mechanism could also be applied to other robots -- possibly even a hybrid of the glider and his grasshopper bot that could hop and fly around before finding a spot to perch itself. Head on past the break to see Kovac explain it himself on video.
Swarm robot project sounds ominous, uses open source
Why would you want to build a 100-strong swarm of mini robots? Well, aside from having them as your minions, you might be able to learn about "artificial self-organization," and "control in large robotic groups," which should come in useful during the inevitable robot insurrection. The swarm robot project, undertaken by the Universities of Stuttgart and Karlsruhe in Germany, aims to produce mini drones that can communicate with one another to avoid collisions, while keeping to a volume of less than three centimeters cubed. Built using open source software and hardware (full list of components is available under the GPL), the latest prototype, titled Jasmine III, achieves those goals while also being able to run "perpetually" thanks to a wireless charging platform. You can see it in close-up after the break, or hit the read link for all the geeky details.
Researchers create wirelessly-powered robot swarm
Wireless power has come a long way from Nikola Tesla's early ruminations on the matter, and it looks like some researchers from Duke and Georgia Tech are now taking the idea to its logical, robot-powering conclusion. While their setup (thankfully) isn't yet able to power robots beyond the confines of the Q L-C resonator-equipped table, it does appear to work remarkably well in that limited proof-of-concept, with five bots each equipped with a non-resonant pickup coil able to follow a path around the table, or simply sit still to recharge their batteries. They were even able to power an LED light with the system for good measure. Natually, they eventually hope to expand the system to power larger swarms of robots and do away with the need for batteries altogether. Yeah, that's a good idea. Head on past the break for a video.
Swarm robots invade UK conference, lets hope they're all accounted for
It looks like the Artificial Life XI conference hosted by the University of Southampton was home to a unsettling number of swarm robots this week, including some we've seen and some we haven't. Among the more interesting of the lot are the matchbox-size bots (pictured above) developed by a group of researchers from the host university, which apparently cost just £24 (or $46) each to produce and are able to independently divide up tasks with no central program controlling them. They're even able to redistribute tasks if some of the robots fail or are removed from the area, which the researchers say makes them ideal for use in far-flung locations and, as the BBC's video available at the link below shows, they're also adorable when set to music.[Thanks, David]
