iRobot shape-shifting ChemBot is back, and it's bad (video)

by Joseph L. Flatley posted Oct 14th 2009 at 6:23AM

As you know, when iRobot isn't hard at work developing some adorable automated vacuum cleaners, it has a quite lucrative sideline in DARPA-funded research projects. On that front, it looks like we finally have some results to report back on that ChemBot project that first appeared on our radar early last year. Unveiled at the International Conference on Intelligent Robots and Systems (IROS) yesterday, this palm-sized troublemaker is being billed as "the first demonstration of a completely soft, mobile robot using jamming as an enabling technology." The "jamming" in question is something called "jamming skin enabled locomotion," which traps air and a collection of loosely packed particles in a package made of silicon rubber. When air is removed from the pocket, the silicon restricts and seems to solidify. The robot consists of several of these pockets, which can be inflated or deflated separately, giving the device the ability to perform simple actions. This is all pretty rudimentary at the moment, but who knows? We may see Flubber in our time, after all. Video after the break.

Video: Precision Urban Hopper leaps over fences, makes enemies cringe

by Darren Murph posted Sep 15th 2009 at 10:46AM

It's only been a few months since we heard from the whiz kids over at Boston Dynamics, and honestly, we've been waiting on pins and needles to see what miracle would emerge from its labs next. Said outfit has just been awarded a contract by Sandia to build the next generation of the Precision Urban Hopper, which will be a four-wheeled jumping robot that can navigate autonomously. When it rolls into battle, it'll also be equipped with a single jumping leg, giving it the ability to hop over fences, giant humans, Gort or anything else that's 25 feet tall. Best of all, testing and delivery is scheduled for late 2010, so if you were planning on getting on our bad side, you should probably have a look at the video past the break. Chances are you'll be second guessing that urge.

DARPA's CALO project, the militaristic Clippy, set to invade iPhones this year

by Tim Stevens posted Jul 30th 2009 at 9:27AM

Microsoft's little Clippy, the uppity paperclip who just wanted to help, never got a lick of respect in the ten years he graced the Office suite. He's long-since gone, but his legacy lives on through a DARPA project called CALO: the Cognitive Assistant that Learns and Organizes. It's intended for use to streamline tedious activities by military personnel, like scheduling meetings and prioritizing e-mails, but there are a few non-com spin-offs intended as well, like an iPhone app called Siri due to hit the App Store sometime this year. Siri will have more of a consumer angle, helping to find product reviews and make reservations, but we're hoping a taste of its military upbringing shines through.

EATR robots claim to be vegetarian... sure

by Vladislav Savov posted Jul 21st 2009 at 6:09AM

Usually when we freak out about the coming of killer robots, nobody bothers to disagree with our histrionics, which is in itself a comforting sign that we're overreacting. On the other hand, if the makers of a chainsaw-wielding robot take the time to point out that it is not a flesh-eating harbinger of the apocalypse, well... Cyclone Power and Robotic Technologies, the companies behind the weaponized EATR drone, have put together a joint press release to comfort us all that the biomass-harvesting machine will be exclusively vegetarian, meaning it would only feed on "renewable plant matter" and not the bodies littering the battlefield. There's no reason not to believe them, though you should remember that in the eyes of a robot, humans are renewable too.

Are memristors the future of Artifical Intelligence? DARPA thinks so

by Joseph L. Flatley posted Jul 14th 2009 at 5:54AM

New Scientist has recently published an article that discusses the memristor, the long theorized basic circuit element that can generate voltage from a current (like a resistor), but in a more complex, dynamic manner -- with the ability to "remember" previous currents. As we've seen, HP has already made progress developing hybrid memristor-transistor chips, but now the hubbub is the technology's applications for artificial intelligence. Apparently, synapses have complex electrical responses "maddeningly similar" to those of memristors, a realization that led Leon Chua (who first discovered the memristor in 1971) to say that synapses are memristors, "the missing circuit element I was looking for" was with us all along, it seems. And of course, it didn't take long for DARPA to jump into the fray, with our fave DoD outfit recently announcing its Systems of Neuromorphic Adaptive Plastic Scalable Electronics Program (SyNAPSE -- cute, huh?) with the goal of developing "biological neural systems" that can "autonomously process information in complex environments by automatically learning relevant and probabilistically stable features and associations." In other words, they see this as a way to make their killer robots a helluva lot smarter -- and you know what that means, don't you?

EATR robots are coming, this isn't funny anymore

by Vladislav Savov posted Jul 10th 2009 at 9:02AM

Oh sure, we joke about rogue AI all the time, and we're aware that we'll probably pollute ourselves to death well before the robots get us, but who really thinks flesh-eating machines are a good idea? The (patently evil) scientists behind the EATR project -- no fair, they're making their own jokes now too -- have reached a new milestone in the development of the reconnaissance bot, successfully coupling a steam generator with a compact biomass furnace. It is now therefore possible for an autonomous machine to forage for and refuel itself with biomatter, otherwise known as soft, pulsating, yummy humans. They call it fuel versatility, as gasoline, diesel, and solar power may also be used if available, yet we'll offer no prizes for predicting which energy source these chainsaw-equipped robots will prefer.

Lockheed Martin and Microvision developing wearable displays for DARPA

by Joseph L. Flatley posted Jul 7th 2009 at 2:33PM

Sure, working with Motorola for some peacetime pico-projector development is one thing, but if you really want to rake in the bucks, you'd better jump on the military-industrial bandwagon. As a part of DARPA's Urban Leader Tactical Response, Awareness & Visualization project, Lockheed Martin has teamed up with Microvision to develop low-profile see-through eyewear displays for providing "non-line-of-sight command and control in distributed urban operations for dismounted warfighters" based on the latter's PicoP technology. The displays will be low-powered, lightweight, and will deliver real-time content for "increased situational awareness, such as real-time combat support and logistics." Sounds pretty similar to the gear they were selling the Air Force years ago, no? In unrelated news, the company's Vice President of Sales and Marketing is named Ian Brown, although we're guessing it's not the same Ian Brown we saw at the Hammerstein Ballroom four years ago. PR after the break.

DARPA contractor shows off tiny robo-hummingbird UAV

by Donald Melanson posted Jul 2nd 2009 at 11:57PM

We've seen plenty of tiny UAVs (or NAVs -- Nano Aerial Vehicles -- as they're also known), but none quite like the robo-hummingbird that's been in development at DARPA-contractor AeroVironment for the past couple of years. While we haven't heard much about it during that time, the company recently completed its most advanced prototype to date, dubbed Mercury, and it's taken advantage of the opportunity to show off all the progress it has made. As you can see in the video after the break, the bot is able to fly about and hover in place by mimicking the wing movement of a real hummingbird and, of course, be controlled completely untethered. What's more, the firm says that the final version will actually look like a real hummingbird as well, and be able to be controlled from up to a kilometer away -- even inside buildings, where a hummingbird won't look at all out of place.

DARPA's programmable matter initiative strives to make the ultimate Swiss Army knife

by Ross Miller posted Jun 7th 2009 at 10:21PM

Remember Intel's shape shifting matter concepts? Well, those realty-bending cats at DARPA are looking to put their own spin on it with a Programmable Matter program of their own. As is their mantra, the long-term goals are pretty wild: researcher Dr. Mitchell R. Zakin is hopeful they can one day build a container that looks like a paint can and will form universal spare parts or tools such as hammers and wrenches based on the soldiers' needs, using a building material they call "mesomatter" that range anywhere from one hundred microns to a centimeter in size. Currently five months into the program's second phase, there's still another fifteen to go before they move on. By then, the group expect to be able to use the technology and assemble four or five different three-dimensional solids. Best be careful, if this falls in the wrong hands, we'll have more "leaked iPhone" images ever previously thought possible.

iRobot's military Ember bots are tiny treaded hotspots

by Tim Stevens posted May 18th 2009 at 7:28AM

Remember the LANDroids initiative, which resulted in iRobot scoring a $2.5 million contract to create tiny, miniaturized bots that could crawl through battlefields and your nightmares? The company is showing off the early fruits of that contract, the Ember microbot, which is so small it slipped entirely under our radar. It's not quite as tiny as DARPA seemed to hope, which depicted a bot little bigger than a pack of cards, but shrinking a Packbot down to paperback size is no small task -- even it is a James Clavell paperback. The bot's primary function is to set up a roving military network on the battlefield, but, with an integrated webcam and extension via USB and SDIO, who knows what kind of functionality they'll provide. The goal is to get these down to $100 or less, and for that price we could see plenty of civilians investing in these just to keep an eye on the activities of household pet insurgents.

DARPA working on "Silent Talk" telepathic communication for soldiers

by Laura June posted May 14th 2009 at 5:41PM

We're no strangers to crazy DARPA projects around here, but this one especially strikes our fantastic fancy. The agency's researchers are currently undertaking a project -- called Silent Talk -- to "allow user-to-user communication on the battlefield without the use of vocalized speech through analysis of neural signals." That's right: they're talking about telepathy. Using an EEG to read brain waves, DARPA is going to attempt to analyze "pre-speech" thoughts, then transmit them to another person. They first plan to map people's EEG patterns to his / her individual words, then see if those patterns are common to all people. If they are, then the team will move on to developing a way to transmitting those patterns to another person. Dream big, that's what we always say!

Robot that can jump twenty-five feet in the air coming to the US military

by Laura June posted May 8th 2009 at 10:17AM

Boston Dynamics -- which previously made a robot called the BigDog -- has been enlisted by Sandia National Laboratories (a US government-funded lab) and DARPA to make a new, hopping robot. Called the Precision Urban Hopper, the robot's goal will be to be capable of jumping over large obstacles in city combat situations. It will boast one extremely tough leg to assist it, in addition to its four wheels. The Hopper is supposedly going to be able to jump 25 feet in the air once completed. So far, only a very small prototype (pictured above) is finished, but Boston Dynamics is due to present its next model sometime during 2010.

Autonomous sniper system combines Xbox 360 controller, .338 rifle for deadly drone action

by Joseph L. Flatley posted Apr 17th 2009 at 10:23AM

You know how it is -- we're frightened and appalled by the thought of unmanned killing machines, but if they must exist we really, really want to play with one. The US Army's latest nightmarish deathcopter / awesome tech toy is a little something called the Autonomous Rotorcraft Sniper System (ARSS). Essentially a .338-caliber rifle mounted to the bottom of a Vigilante unmanned helicopter (though it could eventually be made to work on a Predator drone, for instance), this bad boy utilizes a modified Xbox 360 game controller for targeting while the vehicle itself stays put courtesy of its autopilot functions. Never again will your favorite sniper need to leave the comfort of his barracks! Airborne testing begins in July, with autonomy to come soon after that and a possible robot apocalypse estimated for Q4 2011.

DARPA on the lookout for robotic 'power skin'

by Joseph L. Flatley posted Apr 9th 2009 at 8:16PM

DARPA has put out an RFI for something called Power Skin. The technology is conceived as a structural material that would provide "its own day and night power... to be used as an independent power source and, simultaneously, serve as the structural material" for robots (see our conceptual rendering above) and unmanned aerial vehicles. Ultimately, the military-industrial complex would like to see you develop something that would allow the aforementioned UAVs "indefinite flight endurance," although they'd be totally into it if you could demonstrate continuous flight for a mere four days. We're fairly certain that some of our more clever readers have already developed this technology, so why don't you hit the read link and see if you can't make a few bucks off it? Tell 'em Engadget sent you.

Raytheon developing compact, inexpensive human microwaves

by Joseph L. Flatley posted Apr 8th 2009 at 11:09AM

As you know, if you like your weapons "less than lethal" (but much more than comfortable) the U.S. military is your go-to guy. So great is its love for tormenting folks on future battlefields that the Pentagon has spent a small fortune on devices meant to incapacitate through the use of sound, electricity, and microwaves -- including the Silent Guardian that Raytheon trotted out a while back. According to Wired, the company has recently been awarded a couple interesting contracts relating to their human microwave, including one for a "solid state source for use in non-lethal weapons," and another for gallium nitride development. Details are murky, but GaN -- a semiconductor for missile defense radars -- apparently "looks very promising for high-power microwave amplification," allowing the company to greatly reduce the size and cost of the device. The good news? Defense technology that once took up a whole shipping container and cost several million dollars might be getting much smaller, and cheaper, in the future. The bad news? It really really really hurts.
