Lego-built robotic arm will pour you a drink, collapse under pressure (video)
We've seen countless robotics projects made either partly or entirely out of Lego, but this pneumatic arm built by Max Sheppard has to rank among the most impressive. As you can see in the video above, while it may be a bit on the slow side, the arm's range of motion is remarkably life-like (even by non-Lego standards). It's also able to grip objects of different sizes, and with enough precision to pour water out of a cup, although Sheppard says it can't lift anything more than a couple of pounds. No word if he has any plans to attach the arm to something.

ITK's Handroid: a softer, gentler robotic hand (video)
Most robotic hands are built with a series of individual motors in each joint, making them heavy, expensive and prone to gripping everything with the subtlety of a vice. Japan's ITK thinks it's solved those problems with Handroid -- designed with cords that mimic the muscles in our meat-paws. No motors mean it's far lighter than the standard Terminator design, and it's controlled with a glove that allows it to mirror the operator's movement as it happens. ITK wants to sell Handroid for the bargain price of $6,500 by 2013 for use in environments too dangerous for humans, but because it's so light and cheap it could also see use as a medical prosthesis. You can see how the device works in the video after the break.

Condiment transporting SWITL robot arm gets a gig moving meat, packing boxes (video)
Way back in March, we spotted video of the SWITL, a robotic hand with a penchant for picking up globs of condiments without changing their shape. Neat, yes, but what sort of applications might such a device have in real life, beyond rather inefficient cleanups of Burger King floors? Manufacturer Furukawa Kikou has put the electronic appendage to work, folding meat and packing boxes with bags full of sol-gel substances, without losing the shape of either material. The size of the company is prohibiting sales of SWITL machines overseas at present, but Furukawa Kikou is happy to discuss partnerships, should someone approach it for its raw meat and ketchup moving needs. Exceedingly unappetizing video after the break.

SWITL scoops oozy goop with amazing robotic precision (video)
Look, sometimes, not often, but sometimes we'll miss a truly spectacular and mind bending story that requires a double-back. The SWITL robotic hand is just such a case. The patent-pending technology looks to have been revealed on video back in late October showing the Furukawa Kikou robot deftly lifting a ketchup and mayonnaise mess from a table and then replacing it unchanged from its original shape. The tech was developed for bakeries with the intention of automating the handling of soft substances that were either too malleable or too icky for human hands. Unfortunately, Furukawa Kikou isn't providing any details about the science behind SWITL so we'll just assume that it's Satan's work until otherwise informed. See what we mean in the video after the break.

German robot hand takes a licking, apparently keeps on ticking (video)
Sadists at the German Aerospace Center's (DLR) Institute of Robotics and Mechatronics are showing off their latest development in anthropomorphic appendages: a robotic hand that can take a beating from a baseball bat and still give you the middle finger (or a thumbs-up, we suppose). Researchers apparently designed the limb to function like only a human hand can, and it seems they've done a decent job: it's got five independently functioning fingers, sports 19 degrees of freedom (one less than the real deal), and can even snap them phalanges -- oh no they didn't! It's also got the ability to exert a force of 30 newtons from its fingertips. So what makes it so resilient? The robo-hand has a built-in web of 38 tendons, which allow it to adapt its stiffness under different circumstances: a step away, its creators say, from rigid appendages of the past. There's a video of the hand taking a beating after the jump, but honestly, we'd prefer to see what happens when the hand fights back.

Robotic Yale Aerial Manipulator grabs a can of Guinness
There's plenty of UAVs out there capable of dropping things, but comparatively fewer that are able to pick things up. Some researchers at Yale University doing their part to change that, however, and have recently shown off their so-called Yale Aerial Manipulator; a UAV with a robotic hand. While that may not exactly sound like much, the four-fingered hand is able to "autonomously" grab objects that weigh up to two kilograms while the UAV is in flight, and the helicopter itself is able to reach a top speed of 120 kilometers per hour. That, the researchers say, could let the UAV pick up bombs or packages in difficult to reach areas, or even simply be used to make deliveries in urban areas -- like that can of Guinness you've been craving, for instance. Head on past the break to check it out in action.

BeBionic teases advanced bionic hand, Terminator 5 now has a prop supplier (video)
It won't officially launch until May, but we're already guessing that the folks over at DaVinci are casting quizzical glances towards BeBionic. The UK-based outfit is teasing what it calls the "next generation of fully articulated myo-electric hands," which are said to provide "a range of naturally compliant grip patterns that provide repeatable accuracy" to those who have lost their own hand(s). Better still, the functions (speed, grip force, grip patterns, etc.) can be customized to suit each individual user, and the integrated wireless chip means that said tweaking can take place sans any troubling USB cables. The company's also planning to reveal the planet's first powered wrist with rotation capabilities as well as flexion / extension, and the range just wouldn't be complete without silicone skin available in 19 tones. Hop on past the break for a couple of promo videos -- we get the feeling the world of prosthetics is about to take a huge leap forward.

Prosthetic, robotic 'Smart Hand' has feelings, too
Researchers in Italy and Sweden have spent the last ten years developing what they call the "Smart Hand," a prosthetic hand which enables feeling in its fingertips. The hand -- which was recently wired up to a test patient through a surgical procedure -- has four motors and forty sensors which are linked directly to the brain. In the surgery, the nerve endings of the patient were linked up to receptors in the hand, which allows for feeling in the fingertips of the hand, even though the hand is not really a part of his body. In the video after the break, you can see the greater precision and dexterity this hand allows for. Though the research still needs to be refined before practical use, it looks pretty far along -- and pretty awesome -- to us.

Video: Crafthouse's Melissa robotic hand sounds sweet, looks menacing
Is your poor robot getting by without digits? Without them the poor thing can't greet others, catch ping pong balls, or dial up its cyber-shorties. You need the Melissa Hand from Crafthouse, a servo-driven mitt that's just perfect for your little overlord-to-be. All five fingers open and close at the same time, so it's not ideal for rude robo-gestures, but the videos after the break should give you an idea of what kind of trouble you can get into with the 60mm wide paw. The price? ¥60,000, or about $600. If that's too rich you could always buy a single finger for around $50, but those who need the absolute best can spring for the so-called God Hand, a custom-made model that's a bit smaller (45mm wide) and costs a whopping ¥180,000 -- just shy of $2,000 for a set of left and right. For that kind of money we expect something a little more impressive. [Via Boing Boing Gadgets, Impress]

Robotic hand controlled by compressed air grasps the concept of delicacy
The Robotics and Mechanisms Laboratory (AKA the RoMeLa Project) at the College of Engineering at Virginia Tech has designed and built a prototype robotic hand that is controlled and operated by compressed air. Called RAPHaEL (Robotic Air Powered Hand with Elastic Ligaments), the robot can hold heavier, solid objects, as well as light or delicate ones such as a light bulb or an egg. The hand is powered by a compressor air tank at 60 psi and an accordion style tube actuator, with microcontroller commands operating and coordinating the movements of its fingers. It uses no other motors, and the strength of the grasp is controlled by a change in air pressure, making the hand quite dextrous. RAPHaEL -- which is part of a larger RoMeLa robot project named CHARLI -- has already won several awards, including grabbing first prize at the 2008-2009 Compressed Air and Gas Institute Innovation Award Contest. RoMeLa researchers envision CHARLI one day roaming the VT campus making friends with students and visitors. We look forward to that day, but until then, check out RAPHaEL holding some stuff after the break.

Researchers set sights on uber-dexterous robotic hand
Dr. Honghai Liu, one of the two researchers heading up a project to craft an exceptionally deft robotic hand, has called such a device "one of the holy grails of science," and honestly, we can't say we disagree. He, along with Professor Xiangyang Zhu, was recently award a Royal Society grant to further research the possibility of using artificial intelligence to create software that could "learn and copy human hand movements." A sensor-laden cyberglove has been used to capture data about how the human hand moves, and the duo hopes to eventually use the findings to produce the "perfect artificial limb." Of course, there's no telling how long it'll take for such technology to actually be perfected, but we can already see the line forming with folks eager to swap out their own hand for one a bit more adept.[Via The Raw Feed]

Researchers show off robot hand neural interface
It looks like robot hands have taken yet another step into human-like territory, with a team of researchers at John's Hopkins University recently demonstrating a new neural interface that allows an artificial hand to be used to play the piano. But that's not all! In true mad scientist fashion, to actually control the hand, the researchers relied on neural activity recorded from a monkey's brain. According to MIT's Technology Review, that resulted in the fingers on the hand performing their intended movement about 95 percent of the time. While the system doesn't currently work in real time, the researchers are reportedly planning a live demonstration with a monkey within the next six months. Apparently foreseeing a potential monkey-machine rampage, however, the researchers have wisely decided to only let the monkey control a virtual version of a prosthetic arm.

Robotic hand presented in Japan: death by Powerpoint
Remember that creepy robotic hand we saw terrorizing Japan last week? Well now it's on the loose in some conference room picking up eggs, shaking hands, holding a pencil and crushing a cup with its super action Kung Fu Grip. No video of it crushing skulls but we know what's really going on, we know. Its purpose still isn't any clearer (manufacturing-only or also prosthetics?), only that its functionality is meant to exceed that of the human hand. See just one of many videos after the break.

Squse shows off robot hand with "air muscles"
Japan's Squse looks to be doing its best to keep robots from (unintentionally) crushing anything they get their hands on, recently unveiling a new robotic hand that uses so-called "air muscles" to keep all that superhuman strength in check. Specifically, the hand is packed with artificial fibers that are controlled using air pressure, which makes its movement precise enough to pick up a raw egg without breaking it, yet still no doubt strong enough for it to toss that rule book out the window and go on a five-fingered rampage. While it's one-of-a-kind for the time being, according the the AFP, the company expects to soon ship 50 prototypes to various firms and research institutes, after which it apparently plans to market the hand overseas.

The Nike robotic hand: there is no finish line
Gulp. Meet the 5-finger, robotic hand. We don't know much about it, and quite honestly, we're resisting our every urge to cower in the darkness of our thumb-sucking fear. The flimsy premise seems to be that robotic hands will one day be required to replace the aging work force since so many manufacturing processes have been designed around the dexterity of the human hand. Still, why the uncanny likeness Japan? How about a nice shade of gunmetal grey?

Bionic hand touts can-crushing abilities
Joining the arm, eye, ear, and dolphin (saywha?), the latest bionic creation to come from the doors of the Tokyo Institute of Technology boasts some 33-pounds of crushing power, which could make the Power Glove look a bit weak in comparison. Touted as the "world's first electromechanical prosthetic hand with a grip strong enough to crush an empty beverage can," the creation reportedly weighs a hair over 300-grams and features about half the strength found in the average male hand, but it can extend and flex its fingers in around one second, making sure that the wearer is still a formidible opponent in thumb wars. Unlike similar iterations, however, this rendition utilizes a system of pulleyed cables that run through the fingers, and if all goes as planned, eventual wearers will be able to control the machine by flexing other muscles via "myoelectric control technology." Click on through for a video demonstration.[Via Pink Tentacle]

Researchers create super-sensitive robotic hand
It looks like the ability to grab a can of beans wasn't enough to satisfy those mad scientists at the University of Southampton, who promptly went back to work in the lab to create an even more dexterous and sensitive robotic hand, one that'll let its human controller (or eventual autonomous robot overlord) pick up delicate objects without having to worry about breaking or dropping them. The big advance here, as New Scientist reports, is a set of pressure sensors fitted onto each fingertip that automatically determine the correct amount of pressure to apply, as well as set of so-called "slip-detectors," which can detect even slight amounts of slippage and correct the grip before the object falls crashing to the floor. Eventually, the researchers hope amputees will be able to take advantage of the hand, even linking it directly to their brain. It the meantime, however, 'ol Grippy here will likely continue to defend its undefeated streak in the sport of nerd-machine arm wrestling.

Researchers develop world's smallest robotic hand
The dynamic mad scientist duo of Yen-Wen Lu and Chang-Jin "CJ" Kim at UCLA's Mechanical and Aerospace Engineering Department have reportedly developed the world's smallest robotic hand, measuring just about a millimeter across the fist -- thankfully, small enough not to crush either one of them during testing. The hand's made up of tiny silicon microfingers with polymer-balloon joints, which can be inflated and deflated to open and close with the utmost delicacy. The use of pneumatic operation, as opposed to electrical, also allows the hand to be operated in a wider range of environments, including liquid -- like snapping up a single fish egg in the pic at the right. Robot hands are one thing, but sooner or later you can bet that it'll be attached to a tiny robot body and sent on a not-so-Fantastic Voyage into someone's intestines.[Via Slashdot]
