NASA picks early winners for its ISS robot arm challenge
NASA's bid to crowdsource an arm for its Astrobee cube robot is starting to bear fruit. The agency and Freelancer.com have chosen early winners for the Astrobee Challenges Series, each of which has designed a key component for the robotic appendage. South African grad student Nino Wunderlin produced an attachment mechanism, while Filipino conceptual engineer Myrdal Manzano crafted a "smart" attachment system. Indian software engineer Amit Biswas, in turn, developed a simple deployment mechanism.
Harvard's robot arm can grab squishy sea animals without hurting them
As you might imagine, you can't just grab extra-soft sea creatures like jellyfish or octopuses when you want to study them. Not if you want them to remain intact, anyway. Thankfully, researchers at Harvard's Wyss Institute have a far more delicate solution. They've created a robot arm (the RAD sampler) whose petal-like fingers can quickly form a ball shape around an animal, capturing it without risking any harm. It's simpler than it looks -- it uses just a single motor to drive the entire jointed structure, so it's easy to control and easier still to repair if something breaks.
A robot arm is Prague's latest star DJ
Never mind the debate over whether digital or vinyl is better for DJs -- the real question is whether or not a human should be there in the first place. Prague's Karlovy Lazne club has started employing an automotive robot arm as one of its DJs after its management challenged a robotics company to make it happen. The bot uses custom software to pick songs, and grabs CDs with its pincers to queue up tracks. It can dance and even scratch records. That'd make it more involved in the mix than some DJs we've seen.
This prosthetic arm is powered by Bluetooth and your mind
Robotic limbs aren't a new technology, though the range of motion and strength of such limbs continue to improve. Controlling prosthetics with your mind is another area of refinement, but they're typically connected directly to a patient's brain. A new technique where the robotic arm clicks directly to the bone, however, is showing promise. Johan Baggerman is the first patient in the Netherlands to get a click-on prosthetic arm that he can control with his mind.
Google wanted to sell intelligent robot arms (but didn't)
Google (and parent company Alphabet) build a lot more hardware than fancy new smartphones and AI assistants -- it's just that a lot of it doesn't make it out of the lab. Take these advanced robotic arms, for example: Alphabet's robotics group built the arms, which were used in a research project to show how Google's software helps robots learn from each other over time. But despite their apparent usefulness, Alphabet CEO Larry Page decided to cancel plans to sell the hardware because it failed Page's "toothbrush test." As Bloomberg reports, Page only wants to ship products that could be used daily by billions of people, and these robotic arms are significantly more niche than that.
Amazon robot challenge winner counts on deep learning AI
Amazon's robot Picking Challenge is back for a second year, and it's clear that the competition has learned a lot in that time... in more ways than one. The Netherlands' TU Delft won both parts of the challenge (stowing and picking warehouse items) with a robot that relied on the combination of deep learning artificial intelligence and depth-sensing cameras to get the job done. The machine studied 3D scans of the stockroom items to help it decide how to manipulate items with its gripper and suction cup. That adaptive AI made a big difference, to put it mildly. The arm got a near-flawless score in the stowing half of the event, and was over three times faster at picking objects than last year's champion (100 per hour versus 30).
ICYMI: Saving the ocean and ghosting on love interests
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: The Burner chatbot would let a machine ghost on acquaintances you'd rather not text with anymore. So that's point one for the endtimes, zero for humanity. But this Dutch inventor should more than switch that around with a small prototype of the ocean fence that is designed to collect ocean trash passively, allowing currents to push plastic and other stuff that doesn't belong in the water into a collection fence. If it all works out, a huge, 60-mile long version of his invention will grace the Pacific Ocean within a few years and hopefully be a solution to solving the Great Pacific garbage patch. If you're into Nerf guns, you must watch this video. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
NASA wants your ideas for its cube robot's arm
Think you could build a better robot arm than NASA? You now have a chance to prove it. The agency is teaming up with Freelancer to crowdsource ideas for the arm on Astrobee, a cute cube robot that will float around the International Space Station monitoring conditions and supplies. The first phase will have NASA pick the top 30 entries that meet some basic criteria. If you pass muster, you'll be asked to break down the architecture options for your design. Do that and NASA will run another crowdsourcing effort to solicit ideas for the subcomponents from those 30 submissions. Phew.
Eye-tracking robot arm lets you paint while you eat
One day, you might not have to even touch a canvas to make a masterpiece. Scientists from Imperial College London have developed a system that lets you paint hands-free through a combination of eye tracking and a robotic arm. All you do is adjust your gaze and blink at the right times -- you can even munch on breakfast while you're in mid-oeuvre. The technology is crude at the moment, but it should eventually become intuitive enough that you can focus on perfecting your style, rather than mastering the basics.

A shocking bit of research was just published on the effect some antioxidant supplements had on lab mice with cancer. Turns out it made tumors grow faster than the control group. Meanwhile those happy-go-lucky bike commuters have another new piece of bike tech for signaling to drivers. The Revolights Eclipse Plus syncs with Bluetooth and is being fulfilled through Kickstarter now.
Brain implants control robot arm well enough to grab a beer
A paralyzed man named Erik Sorto has finally been able to drink beer on his own after 13 years, and it's all thanks to a robotic arm controlled solely by his mind. If you've been following our robotics coverage, you'll know it isn't the first mind-controlled robo limb -- a DARPA-funded project once allowed a woman to feed herself chocolate, while the one developed by the Braingate2 consortium helped another woman drink coffee on her own. This particular technology, however, works quite differently from the others. Its creators, a team of researchers from various institutes led by Caltech, implanted the neural chips needed to control the arm into a part of the brain called "posterior parietal cortex" or PPC.
Disarm a bomb with your hand, a robot arm and Leap-motion controller
Neutralizing explosives, it turns out, is a delicate and complicated procedure -- but a company called Mirror Training hopes to make it simpler. "Our company has built an interface that literally uses your own hand and arm to move a robotic arm," announced CEO Liz Alessi. "I like to call it 'wear your robot.'" The interface uses a Leap Motion controller to detect an arm and hand movements, allowing a bomb squad robot to directly mirror its operator's actions. In tests, Alessi says, it has allowed operators to disarm mock-bombs twice as fast as traditional control methods.
Students build a robot arm you control with the wink of an eye
Want proof that you don't need big, specialized equipment to produce a mind-controlled robot arm? Just look at a recent University of Toronto student project. Ryan Mintz and crew have created an arm that you control using little more than a brainwave-sensing headset (which is no longer that rare) and a laptop. The team's software is smart enough to steer the arm using subtle head movements, such as clenching your jaw or winking your eye; it also knows when you've relaxed.
Columbia University's low-cost robotic arm is controlled by facial muscles, we go face-on (video)
We've seen Emotiv's Epoc headset control cars and trapeze acts, but now a small posse of students at Columbia University is teaching it how to control a robotic arm. The appendage, aptly named ARM for Assistive Robotic Manipulator, was envisioned as a wheelchair attachment to help the disabled. According to the team, the goal was to keep costs in the neighborhood of $5,000 since insurance outfits Medicare and Medicaid won't foot a bill for assistive tech that's much more than $10,000. To keep costs low, the crew built the limb from laser cut wood, and managed to keep the final price tag at $3,200. Since picking up EEG signals and interpreting them accurately can be tricky, the group says it settled on monitoring EMG waves, which are triggered by muscle movements, for additional reliability. Lifting your eyebrows makes the device open its grip, clenching your teeth shuts it and moving your lips to the left and right twists the claw, while other motions are currently handled by using a PlayStation 2 controller. In the lab, the contraption has seven degrees of freedom, but it was reduced to five when we took it for a spin. It was hit or miss when this editor put the headgear on, between making sure facial gestures were spot on and the equipment's attempts to pick up clear signals.%Gallery-187534%
MIT algorithms teach robot arms to think outside of the box (video)
Although robots are getting better at adapting to the real world, they still tend to tackle challenges with a fixed set of alternatives that can quickly become impractical as objects (and more advanced robots) complicate the situation. Two MIT students, Jennifer Barry and Annie Holladay, have developed fresh algorithms that could help robot arms improvise. Barry's method tells the robot about an object's nature, focusing its attention on the most effective interactions -- sliding a plate until it's more easily picked up, for example. Holladay, meanwhile, turns collision detection on its head to funnel an object into place, such as balancing a delicate object with a free arm before setting that object down. Although the existing code for either approach currently requires plugging in existing data, their creators ultimately want more flexible code that determines qualities on the spot and reacts accordingly. Long-term development could nudge us closer to robots with truly general-purpose code -- a welcome relief from the one-track minds the machines often have today.
German robot arm learns ping-pong as it plays humans, might rival its masters
We like to tell ourselves that learning by doing is the best strategy for improving our skills, but we seldom apply that philosophy to our robots; with certain exceptions, they're just supposed to know what to do from the start. Researchers at the Technical University of Darmstadt disagree and have developed algorithms proving that robot arms just need practice, practice, practice to learn complex activities. After some literal hand-holding with a human to understand the basics of a ping-pong swing, a TUD robot can gradually abstract those motions and return the ball in situations beyond the initial example. The technique is effective enough that the test arm took a mere hour of practice to successfully bounce back 88 percent of shots and compete with a human. That's certainly better than most of us fared after our first game. If all goes well, the science could lead to robots of all kinds that need only a small foundation of code to accomplish a lot. Just hope that the inevitable struggle between humans and robots isn't settled with a ping-pong match... it might end badly.
Ibis hotels to have robots paint art while they track your sleep: no, that's not creepy at all (video)
First they invaded our factories, and now it's our hotel rooms. Is nowhere safe from the robots? In truth, Ibis' upcoming Sleep Art project is very slick, even if it smacks of robot voyeurism. Ibis hotels in Berlin, London and Paris will let 40 successful applicants sleep on beds that each have 80 sensors translating movements, sound and temperature into truly unique acrylic paintings by robotic arms connected through WiFi. You don't have to worry that the machines are literally watching you sleep -- there's no cameras or other visual records of the night's tossing and turning, apart from the abstract lines on the canvas. All the same, if you succeed in landing a stay in one of the Sleep Art hotel rooms between October 13th and November 23rd, you're a brave person. We all know how this ends.
Ford wants you to meet its touchy, feely interior quality robot, RUTH 2.0
That's RUTH. In the end, she really amounts to a big robot arm with six joints, but Ford clearly has a soft spot for the faceless employee. First utilized in Europe, the Robotized Unit for Tactility and Haptics is currently at work helping to tweak the interiors of the company's 2013 Fusions, turning data collected from customers across the world into the hard to define concept of "quality," touching the trim, pushing buttons and turning knobs in the interior of the vehicle, in order to help provide what Ford says is, "the same type of quality they might feel if they were to buy a high-end luxury car." The version of the arm dubbed Ruth 2.0 is currently being used by Ford alone in North America, and the company has extended her quality checking to include seat comfort in the vehicles. Check out a video of the long arm of the car company after the break.
Northeastern University students develop eye controlled robotic arm that's happy to feed you
As an alternative to receiving brain implants for robotic arm dominance assistance, check out this surprisingly cheap eye-tracking solution developed by six electrical engineering students at Northeastern University. Labeled iCRAFT, for eye Controlled Robotic Arm Feeding Technology, the award-winning senior project drew its inspiration from one team member's difficulty syncing spoonfuls with the eating pace of elderly and disabled patients. Simply gaze at the on-screen box that corresponds to your food or beverage choice and the robotic arm will swing your way with grub in its grip. Ambitious DIY-ers can chase down the open-sourced software behind iCRAFT, and construct a contraption of their own for about $900 -- considerably less than self-feeding rigs living in the neighborhood of $3,500. You can catch a video of the robot arm serving up some fine Wendy's cuisine after the break.
Mind-operated robot arm helps paralyzed woman have her cup o' joe (video)
Researchers at the Braingate2 consortium have made a breakthrough that allows people with spinal cord or stroke injuries to control robotic limbs with their minds. The original project allowed subjects with motor cortex-implanted chips to move cursors on a screen with their minds, but they can now command DEKA and DLR mechanical arms to grasp foam balls and sip coffee. Researchers noted that dropped objects and missed drinks were frequent, but improved brain sensors and more practice by subjects should help. To see the power of the mind move perhaps not mountains, but good ol' java, jump to the video below.
