Rethinking the robot hand at Harvard (video)
Should you ever find yourself needing to discuss the state of the robotic hand in the early 21st century, Harvard professor Robert Howe seems about as good a place to start as any. The professor founded the school's BioRobotics Laboratory in 1990 and has devoted a good deal of his time to the quest for perfect robot extremities. The last few years have seen a number of breakthroughs for Howe and his team including, notably, the SDM (Shape Deposit Manufacturing) hand, an adaptable and rugged robot gripper that utilizes a single motor to manipulate its eight joints. Such machines have, in the past, often relied on precise image sensing to determine the exact size and shape of an object, in order to configure their digits perfectly before attempting to pick it up. The SDM hand is a lot more forgiving. The pulley system at play distributes equal tension to the fingers in an adaptive transmission that allows motion to continue in other fingers, should one's movement be hampered. The joints themselves are extremely compliant as well, adapting and conforming to the shape of an object, thanks in part to their ability to pivot in three dimensions. The Shape Deposit Manufacturing technology used to create the fingers, meanwhile, adds an important level of durability, letting Howe bang them against a table (a trick he happily performed for us) and expose them to water -- both features that are quite often absent in more complex (and far more expensive) models. The SDM technology, developed at Stanford, allows for the creation of fingers that are a single piece, with their parts embedded in plastic. The larger model shown off by Howe serves as great visual when describing the benefits of the single motor system, but the team has also developed a smaller version, with the requisite motors embedded in a far more compact chassis, which we also got a peek at. The hand will likely be targeted at home and office use, with some key applications for assisting the disabled. Check out a video of Howe describing the technology to us during our visit to the school and a clip of the SDM doing its thing in the labs, which should help feed your desire to watch robot hands get banged by hammers.%Gallery-161775%
DARPA's 'Avatar project' aims to give soldiers surrogate robots, make James Cameron proud
In a fevered mash up of blockbuster films directed by James Cameron, DARPA is looking to put soldier controlled bi-pedal robots on the battlefield. Think Terminator meets Avatar. The agency has set aside $7 million of it's $2.8 billion 2012 budget to develop an "Avatar program" that will "develop interfaces and algorithms to enable a soldier to effectively partner with a semi-autonomous bi-pedal machine and allow it to act as the soldier's surrogate." DARPA isn't talking about simple remote control rigs, either -- these 'bots are being designed to clear rooms, and facilitate sentry control and combat casualty recovery. The new budget also sets aside $4.1 million to design laser countermeasures to protect military weapons, well, lasers -- ensuring that the future's robot soldiers will be nigh indestructible when they rebel against their human hosts.
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.
Padlette, for those times you need a giant rubber band on your iPad
The Padlette solves one problem: How do you strap your iPad to your hand quickly using a big rubber band? Insofar as that one problem is concerned, the Padlette (patent pending) does a great job. You stretch the loops around the corners of your iPad and you're able to slip your hand in between, securely holding the iPad with one hand. How secure is it? I stood over a bed and shook my hand around but wasn't too worried the iPad would fly off. In fact, you might be surprised how secure this thing is -- the rubber sticks well to the iPad but won't rip the hair out of your hand (I have moderately Hobbitish hand hair, YMMV). I suppose you could attach the iPad to a golf club or pole or use the Padlette to hold your magic wand between wizard duels, but that isn't its primary purpose. Anyway, the Padlette isn't new, but they were at CES hoping to score some larger notice and distribution. There's also a few versions of this, but frankly I couldn't figure out why -- they appear to be grippable in different ways? There's the deefour, the deethree and the new yinyang, all using the same idea but with a different hole cut in the middle of the rubber band. I don't think this would sell well in a Target, as it seems primarily suited to trade shows or teaching or somewhere you might need to hold the iPad safely in one hand. Which isn't that often, frankly. The Padlette comes in a variety of colors and costs $19.99 on Amazon. Oh, and it supports any full-size tablets for you cross-platform fans out there.
Honda's ASIMO robot sheds a few pounds, gets all autonomous on us (video)
We've already seen it dance, sing and read minds, but Honda's ASIMO humanoid has now taken that one great leap into decidedly more dystopian territory. The revamped bot, pictured above (and apparently doing its best Herman Cain impression), was unveiled today in Japan, sporting a streamlined physique and scarily adept mind. In fact, Honda claims that its bot is now less "automated" than it is "autonomous" -- all thanks to new behavior control technology that allows it to move and make decisions on its own, independent of human operators. Its external recognition capability and set of onboard visual and auditory sensors enable it to rapidly process information about its environment, which the ASIMO then uses to plot its next move. Combining long- and short-term sensor data, the droid can predict human movements and automatically recognize voices or gestures. Because of this, Honda says, the ASIMO could be more easily integrated within social environments, and peacefully coexist with its human prey counterparts. Physically, meanwhile, the robot's looking svelter than ever, having shed a full six kilograms. It can now run at a maximum speed of 9 kilometers per hour, jump up and down for as long as it wants, and even hop on one leg, should it ever need to. Plus, its hands are now more dexterous than ever, thanks to new independent finger control functions that allow it to handle the most delicate of tasks -- like pouring you a stiff one after work, or before your inevitable demise. Check out more images in the gallery below, or hop past the break for a video and accompanying press release. %Gallery-138746%
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.
BBC shows us what it's like to live with a bionic hand
We've posted a fair share on bionic limbs and their advancements over the years, but rarely have we had the chance to see a video of one in real world use, on a real person. The BBC has shared a video of a man named Patrick using his bionic arm, which -- long story short -- was partially the result of being electrocuted at work. This is his second one to date and specifically, it's a prototype Otto Bock mind-controlled prosthetic arm equipped with six nerve sensors that let him use the hand as if it were his own -- it supports pinching and gripping with the fingers as well as lateral and circular movement of the wrist. Although the footage is a mundane roll of various day to day tasks -- gripping a bottle to pour a glass of water for instance -- it's quite amazing to realize technology is helping him do things he'd otherwise be deprived of. We'd suggest checking it out at the BBC by clicking the source link below.
Microsoft's Rock and Rails touchscreen lets you massage your photos with both hands
If you ever get tired of poking away at your smartphone's screen like a doorbell, you're not alone. The forward-looking folks over at Microsoft Research have been working away at a new touchscreen system designed pick up on more natural, whole-hand movements, effectively allowing users to break free from the finger-based paradigm that governs most tactile devices. Developed in coordination with engineers at Microsoft Surface, the company's Rock and Rails interface can detect three basic hand gestures: a balled fist, which holds items on the screen, an extended hand that can align objects (see the cell marked "d," on the right) and a curved paw, around which users can pivot images (see cell b). This taxonomy opens up new ways for users to crop, re-size or generally play around with their UI elements, though it remains unclear whether the display will trickle down to the consumer level anytime soon. For now, it appears to operate exclusively on the Surface, but more details should surface when the system's developers release a paper on their project, later this year. Hit the source links to see a video of the thing in action.
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.
Robot hand hits 20WPM, nearly ready to embrace infinite monkey theorem
Robot hands have been grabbing, crushing, drawing and otherwise actuating for years, but have you ever seen one properly type? That's the primary purpose of a new Virginia Tech design. Engineers built this Dexterous Anthropomorphic Robotic Typing (DART) hand to mimic the real deal as best they could, down to individually-actuating three-segment digits and 110 degrees of wrist rotation in a package the size of a real human arm. Using a total of 19 servo motors and high tensile strength wire for the tendons, they managed to create a single mechanical paw that can achieve an estimated 20 words per minute while typing. Next, they plan to cover it in silicone skin and add piezoelectric sensors to provide tactile feedback. Imagine that: the next time a secret family member severs your arm with a focused plasma beam, you'll know where to go for replacement. Find a quick video and the full scientific paper at the links below.
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.
University of Chicago, Cornell researchers develop universal robotic gripper
Robotic hands are usually just that -- hands -- but some researchers from the University of Chicago and Cornell University (with a little help from iRobot) have taken a decidedly different approach for their so-called universal robotic gripper. As you can see above, the gripper is actually a balloon that can conform to and grip just about any small object, and hang onto it firmly enough to pick it up. What's the secret? After much testing, the researchers found that ground coffee was the best substance to fill the balloon with -- to grab an object, the gripper simply creates a vacuum in the balloon (much like a vacuum-sealed bag of coffee), and it's then able to let go of the object just by releasing the vacuum. Simple, but it works. Head on past the break to check it out in action. [Thanks, Jeremy]
Scientists formalize perfect handshake; world peace on track for 2012
PH = (e² + ve²)(d²) + (cg + dr)² + π{(4< s >2)(4< p >2)}² + (vi + t + te)² + {(4< c >2)(4< du >2)}² Where (e) is eye contact (1=none; 5=direct) 5; (ve) is verbal greeting (1=totally inappropriate; 5=totally appropriate) 5; (d) is Duchenne smile - smiling in eyes and mouth, plus symmetry on both sides of face, and slower offset (1=totally non-Duchenne smile (false smile); 5=totally Duchenne) 5; (cg) completeness of grip (1=very incomplete; 5=full) 5; (dr) is dryness of hand (1=damp; 5=dry) 4; (s) is strength (1= weak; 5=strong) 3; (p) is position of hand (1=back towards own body; 5=other person's bodily zone) 3; (vi) is vigour (1=too low/too high; 5=mid) 3; (t) is temperature of hands (1=too cold/too hot; 5=mid) 3; (te) is texture of hands (5=mid; 1=too rough/too smooth) 3; (c) is control (1=low; 5=high) 3; (du) is duration (1= brief; 5=long) 3. It's that easy! Perhaps just as interesting is the fact that this formula was arrived at by University of Manchester scientists hired by Chevrolet "as part of a handshake training guide for its staff to prepare them ahead of the launch of the new 5 Year Promise offer, which aims to offer peace of mind and reassurance to its customers." Now excuse us while we go practice with our best friend for the rest of our useful lives. [Image courtesy of Aidan_Jones]
Kingdom Hearts Re:Coded for DS revealed in Square Enix E3 lineup
Square Enix has announced its lineup of games to be shown at E3, and, while there may be surprises yet to be revealed, the company has already unveiled a rather big one. Kingdom Hearts Re:Coded, a new DS game by 358/2 Days developer h.a.n.d., will be on display at the show. The game sounds like an action-RPG remake of the Japan-only mobile game Kingdom Hearts: Coded, in which a virtual Sora retraces his steps through the original Kingdom Hearts. "Jiminy Cricket is looking over the journal he used to document his first adventure with Sora when he discovers a mysterious message," according to the description of Re:Coded included in Square's E3 press release. "He didn't write it – so how on earth did it get there? King Mickey is determined to find out, so he and his friends decide to digitize the journal and delve into its deepest secrets. Inside this "datascape" dwells a second Sora who is about to embark on a grand adventure of his very own." The game currently has a "TBD" release date. Square Enix didn't specify how much of the game would be shown, but considering it's just been announced, we expect little more than a trailer.
BeBionic officially unveils its incredible myo-electric bionic hand
Back in February when we first caught wind of BeBionic's myo-electric, very realistic bionic hand, we were quite impressed. The finished product was just unveiled at ISPO World Congress in Leipzig Germany, and it's looking even better than our first glimpse gave away. We don't know a ton more about how the hand functions -- it boasts a fully integrated wireless chip, fully customizable functions to control speed, grip force, and grip patterns, plus aesthetic bonuses such as silicone skin overlays in 19 different tones. The BeBionic hand is now due for worldwide distribution in June of this year -- but check out the teaser video below if you're still curious.
iCub gets upgraded with tinier hands, better legs
We're pretty familiar with iCub -- the humanoid robot modeled on a two year old -- around here. Just because we know him well, though, doesn't really change the fact that we get the slightest chill running down our spine every time we're reminded of his existence. Well, iCub's getting an upgrade which includes newer, lighter legs which will be more impervious to damage, and smaller hands. That's right, the youngster, who is about toddler-sized, has had until now, the hands of an eight-year old: pretty embarrassing for the little fellow. The new hands are the right size, and have the correct dexterity as well. Regardless, he's still a little creepy, but as you'll see in the video after the break, impressive none the less.
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.
DARPA job posting talks of developing an autonomous, grenade-wielding robot
DARPA's just put up a pretty interesting job posting... if you're the wary-of-our-future-being-controlled-by-robots type, anyway. The call involves a new research and development program called ARM. Basically, DARPA's looking to build a robot that can use its arms to dexterously and autonomously grasp objects. The quote from the job posting which is raising eyebrows around here says that the bot should be able to "hold an inert grenade with one hand, and pull the pin with the other hand" without any direction from humans. Now, we're not really trying to hit the alarmist angle, and we're all for advancements in robot tech... but it seems to us we'd have less to worry about if the job posting had said "should be able to hold a kitten in one hand, and pet it with the other." Right guys?
Deanmark's AirMouse looks more like a ragged glove, less like an input peripheral
Controller-type devices baked into wearables have been around since the late 17th century (though we can't seem to recall one in particular that was made before Nintendo's Power Glove), but frankly, we haven't seen a whole lot of innovation in this department over the past few years. Deanmark's AirMouse is hoping to change all of that, but if we didn't know any better, we'd say Microsoft kind of called this concept first. Anywho, the strap-on mouse -- which doesn't seem to boast any sort of price or release date -- attaches on one's wrist and fingers in order to place sensors on areas where you'd normally mouse. Naturally, the company claims that this approach helps fend of repetitive stress injuries and also enables a new level of multitasking, but until doctors start gluing these things to our hands at birth, we get the feeling that most folks will simply stick to what they know when it comes to cursor pushing.
