MIT robot's flytrap gripper can grab both fragile and heavy objects
Robot hands tend to skew toward extremes. They can pick up delicate objects or heavy objects, but rarely both. MIT CSAIL's solution? Avoid hands altogether. Its researchers have developed a Venus flytrap-like gripper that can grab objects as fragile as a grape, but also items 100 times its weight -- even if they're oddly shaped. The trick relies on a combination of clever physics with brute force.
The next robot crawling through your gut could be a gummi bear
The future of robotics is decidedly squishy. We've already seen gel-based 'bots that can catch fish, mimic octopi and even ones that can keep your heart pumping. And, if the researchers from Switzerland's EPFL are successful, they could soon be crawling around in our intestines as well.
Willow Garage may sell its Velo robot gripper early, if you ask nicely
Some have called Willow Garage's health into question lately, but the company may have a minor hit on its hands -- if through an unexpected channel. The firm has seen a strong enough response to its Velo robot gripper that it's mulling an early sale of the device this fall, at an educational price somewhere between $500 and $1,000. Whether or not that happens depends on feedback, however. Willow Garage is both offering notification sign-ups and running a feature survey -- if you need a different interface or better performance, now's the time to speak up. There's no guarantee of receiving a Velo when the company might ship just 50 to 100 of the advance units, but you won't get one if you don't ask, will you?
Gecko-inspired water-powered robot scales glass, washes windows (sort of)
We've seen some pretty impressive Spidey-like robots in our time, but honestly, crawling walls isn't always enough to pique or interest. A robot that can scale buildings and wash windows -- now that's something to get excited about. Like this little wall climber, the gecko-inspired machine enlists the Bernoulli principle, using the flow of water through fluidic vacuum generators that allow the reptilian robot to get a grip on smooth surfaces. Next, the water is directed through a solenoid valve to a piston in the robot's spine, and finally, the excess liquid is expelled and used to get glass gleaming. Currently, the little machine is capable of carrying twice its weight, and uses a small battery to power a "wireless communication system" and the servos used to control its direction. We're definitely intrigued, but judging from the video (after the break), we're pretty sure it's no match for flesh and blood window washers.
Climbing robot can scale walls on a supersonic stream of air, won't leave fingerprints behind
There are plenty of wall climbing robots roaming the Earth, but few can scale heights as gracefully as this little guy can. Developed by researchers at the University of Canterbury in New Zealand, this bot can wind its way across any glass, metal or cloth terrain, without even touching its pods to the surface. The secret lies in Bernoulli's Principle, which states that as the speed of a fluid increases, its pressure decreases. This phenomenon also applies to streams of air, which, when moving at high speeds around of a circular gripper, can create a vacuum strong enough to hold things without actually touching them. In this case, air shoots out of the robot's feet at more than 2,000 miles per hour, creating enough pressure to lift the craft, while holding it close to the wall. The technology isn't new, but rarely can it support the weight of an entire device -- let alone the extra cargo that this climber's non-contact adhesive pads can hold. Researchers say the supersonic grippers will be available in "some months" and will probably cost "a few hundred dollars." As for the bot itself, Canterbury's engineers envision it being used for industrial inspections -- though the more we think about it, the more we realize just how dirty our windows are.

Game Gripper continues its evolution with a new Epic 4G model, Genesis button layout (video)
Sweet, sweet Game Gripper. You make smartphone gaming a rather less cramping experience, and now you're spreading joy to the fourth generation. Owners of Sprint Epic 4G can now get their Gripper on, and can do so with a lovely new Genesis-inspired layout that offers two rows of three buttons plus a D-pad -- and then another four buttons for good measure. It's rather excitedly demonstrated after the break and, like the earlier models, will set you back $14.99. Now, if only we could get handset makers to start adding shoulder buttons on their cellies.
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]
Revenge of the quadrocopters: now they move in packs (video)
In case you didn't find the original quadrocopter chilling enough, the GRASP Lab out of the University of Pennsylvania has gone and added a bit of cooperative logic to the recipe so that now multiple little drones can work together. Also upgraded with a "claw-like" gripper that allows it to pick up and transport objects, the newer quadrocopter can team up on its prey payload with its buddies, all while maintaining its exquisite balance and agility. Skip past the break to see it on video.
Swallowable microgrippers could make surgery more / less invasive
While the scientists that developed these newfangled ingestible microgrippers call them minimally invasive, we're not so sure that swallowing minuscule devices that can cut and grab tissue when chemically activated fits our definition of keyhole surgery. Nevertheless, tiny "handlike grippers" are currently being shown off to highly intelligent professionals in the medical realm, and if proven feasible, they could one day be used to perform biopsies from within. More specifically, the devices could reportedly "react to the biochemicals released by infected tissue by closing around the tissue, so that pieces can be removed for analysis." Yeah, we reckon this is a bit less painful than actually going under the knife, but the mere thought of having blade-wielding microorganisms floating around our innards spooks us just a wee bit. Go on, fling your "pansies!" this way -- we can take it.[Via medGadget]
Researchers develop robotic tweezers that can grasp single cells
Usually when we talk about robot grip strength, it's in the context of being slowly crushed to death during a violent robot uprising, but it appears we now have to fear our bodies being stolen away cell-by-cell as well. That's the terrifying reality being brought to life at the University of Toronto, where researcher Yu Sun and his team have developed semi-autonomous microscopic robo-tweezers that can sense touch and grip strength acutely enough to pick up and move individual heart cells during tests without damaging them. The tiny rig is just .1 inches long, and the grippers on the ends are fine enough to pick up cell just 10 micrometers wide. So far they've just been arranging cells during testing, but Yu says eventually they can be used to assemble silicon parts on circuit boards, or even engineer tissue. No word on when these might hit production, but when they do Yu says he expects them to cost just $10 each. At least the revolution will be inexpensive, we guess.
