Northeastern University targeted by anti-VR bomber
Northeastern University's VR lab was the victim of a bomb attack, and the perpetrator has a grudge against Mark Zuckerberg.
New wristband could predict aggressive outbursts in people with autism
Researchers are hoping a new wearable wristband will help predict aggressive outbursts in people with autism. The device monitors heart rate, sweat production, skin surface temperature and arm movements. It can predict outbursts 60 seconds ahead of time with 84 percent accuracy. While that might not seem like much time, it could give caretakers an opportunity to relax the individual wearing the wristband and make sure everyone is safe.
Fingertip sensor lets robots 'see' what they're touching
We've seen robotics improve by (literal) leaps and bounds recently, but what about more nuanced things, like a fine sense of touch? Researchers at MIT and Northeastern University are showing off a new fingertip version of the GelSight sensor, a cube-shaped attachment that uses a camera and a sensitive rubber film to 3D map the objects they're grabbing. That new level of precision, the team says, could lead to more independent robots that are better able to manipulate their environment.
TRAQ quadricopter locates and hones in on radio signal sources (video)
Move over, Parrot AR.Drone; there's a new (prototype) quadrocopter in town. For their senior project, electrical engineering students at Northeastern University developed TRAQ, an autonomous aircraft that tracks down the sources of radio transmissions. That functionality comes thanks to a four-element antenna array, and the team envisions such a device being used in disaster, rescue and surveillance situations, where drones could prove faster to respond than us earthbound humans. The next step would be getting multiple aircraft to work together to improve location accuracy. Who doesn't love an imposing swarm of quadrocopters, after all?
RISE:2013 highlights: Kinect rehab, Lego lobsters, 3D printed tech and more
We were excited and honored when the administration at Northeastern University asked us to help judge its RISE:2013 Research, Innovation and Scholarship Expo. The event, held at the physical education center on the school's Boston campus, brings together an incredibly diverse array of research projects covering a impressive number of fields, including physical and life sciences, engineering, humanities, arts & design, computer and information sciences, health sciences, law, business and social sciences. As you might imagine, scoring works across such a diverse array of concentrations is no easy task. We did, however, manage to pull out a handful of projects that will no doubt be of particular interest to our own readership. The list includes the use of a Kinect camera and PC for physical rehabilitation, the 3D printing of embedded electrical technologies, a Lego set that helps bridge the gap between crustacean and robot and a device that employs an Arduino board and video games to help stroke victims recover motor skills. Check out a video of all of the above just after the break.
Nexi robot helps Northeastern University track effects of shifty body language (video)
MIT's Nexi robot has been teaching us about social interaction for years, and has even done a stint with the US Navy. Its latest role, however, involved studying those moments when society falls apart. Northeastern University researchers made Nexi the key ingredient of an experiment where subjects were asked to play a Prisoner's Dilemma-style game immediately after a conversation, whether it was with a human or a machine. Nexi showed that humans are better judges of trustworthiness after they see the telltale body language of dishonesty -- crossed arms, leaning back and other cues -- even when those expressions come from a collection of metal and plastic. The study suggests not just that humans are tuned to watch for subtle hints of sketchy behavior, but that future humanoid robots could foster trust by using the right gestures. We'll look forward to the friendlier machine assistants that result... and keep in mind the room for deception when the robots invariably plot to take over the world.
WiFi-Extending Robot is built like a tank -- we talk to the people behind the project (video)
It's a fairly menacing sight, an aluminum robot sporting big tank treads -- that is, until you watch one of its creators do a handstand on top of the thing in a pair of cargo shorts. And really, while the 'bot wouldn't look too out of place with a small machine gun strapped to its front, its intentions are peaceful, seeking to extend the WiFi connections to hazardous places lacking in network infrastructure. We first heard about the project last week, when the team of computer and electrical engineers at Northeastern University that created it first revealed their work to the media. A visit this weekend to our favorite Somerville, Massachusetts-based hackerspace provided the opportunity to check out the beast in-person and discuss the project with a couple of its creators. After the limited machining resources at Northeastern failed to meet their needs, the students found a home at Artisan's Asylum, where they learned the skills necessary to put together this ambitious project, utilizing classes and the metal shop provided by the space. The result is an impressive sight, a robot capable of climbing stairs and supporting the weight of two adult humans -- the latter of which they happily demonstrated for us in a yet-to-be-occupied new wing at Artisan's. The former, on the other hand, we were unable to see, sadly, as the internals were mostly gutted at the moment on the ever-evolving project. Team member Dan Landers, was more than happy to discuss the project, standing next to a pile of water jet-cut steel pieces that will form the first leg of giant hexapod Stompy, a project on which Landers is also a participant.%Gallery-161804%
iCRAFT robotic feeding arm (eyes-on)
We're back for another day of exploring the Northeastern University labs. We checked out a handful of projects yesterday, including the HyCycle, a runner-up in the school's Capstone award. Today we checked out the winner: iCRAFT -- that's short for eye-Controlled Robotic Arm Feeding Technology. The project was developed by a group of seven electrical and computer engineering students looking to create an inexpensive solution for helping the disabled and elderly feed themselves at home. As the Apple-esque name implies, the project utilizes eye-tracking to help the user feed him or herself. The hardware side of the project involves a robotic arm and controller (which run a combined $640), a hacked Creative webcam and IR light (around $114), three bowls, a water bottle and a custom built power supply. On the software side, the team used the open-source ITU gaze tracker software, combined with a custom GUI. The whole thing is designed to be simple to use right out of the box -- though, being in prototype stage, there were naturally a few hiccups in the process. It didn't work perfectly when we demoed it today, but it certainly wasn't much more buggy than what many companies try to pass off as finished products. %Gallery-158173%
ATLAS bimanual-rehabilitation glove system hands-on (video)
The Squid Shirt that we checked out earlier today at Northeastern University certainly has the potential for healthcare use beyond straight off-season workout sessions, but the ATLAS project is an even purer expression of that application. The name is an acronym for the rather unwieldy Angle Tracking and Location At home System. In short, the system is a bimanual-rehabilitation glove system, a tracking device that utilizes two gloves to monitor the hand movements of stroke victims. The "Home System," part of the name, meanwhile, signifies its creators' intention to eventually release the ATLAS as an at-home testing system, allowing users to get more regular readings than industrial versions. The system is comprised of two standard black gloves -- the first version (it's currently on version three), assistant academic specialist Mark Sivak tells us, was comprised of gold lycra gloves. The gloves have bend sensors in each finger and internal measurement sensors on the back of the hand. The bend sensors are anchored on the back of the hand, located beneath a moveable flap. They're embedded in the glove, running down each finger. The hand orientation inertial sensor is comprised of an accelerometer, gyroscope and magnetometer located on a box strapped to the top of the glove. The bend sensors feed straight into a box with an Arduino Mega inside, while the inertial sensors first pass through their own Arduino microcontrollers before rejoining the data feed back to the PC.%Gallery-158061%
HyCycle electric bike hands-on (video)
The HyCycle isn't the kind of thing you'd want to have to take through airport security -- at least not in its present state. The electricity-generating electric bike prototype is bit of a mess of wires and blinking boards at the moment, plus a battery that looks an awful lot like a block of C4. All are attached to one of its creators' rust-colored Schwinn road bike. The bicycle is a project of a group of Northeastern students, an attempt to build a cheaper electric bicycle -- one that can be offered as a do-it-yourself kit that users can snap to their existing bike frame.
Northeastern University Squid Shirt torso-on
It seems like everyone's got a solution for workout tracking, these days, and the undergrad students at Northeastern University are no different. We traveled to the bowels of the Boston school's Egan Research Center, to try the Squid Shirt that we saw back in February on for size. Our own Terrence O'Brien donned the garb, and while the current prototype has dropped much of the unwieldy wires and suction cups that gave the wearable its name, it's still a bit of a production, taking several minutes to put on with the aid of assistant academic specialist, Mark Sivak (who assured us that the student this specific model was designed for had gotten the whole thing down to a two or three minute streamlined process). The shirt has a total of 13 EMG sensors, monitoring data from three muscle groups: the pecs, lats and delts. Every signal requires two sensors (with one attached to the hip for ground), which are ultra cheap and disposable, meaning you can just toss them away at the end of each workout session. In addition to monitoring muscle activity, a standard Polar heart rate monitor slips into a sleeve inside the shirt to keep track of your pulse. The shirt itself is machine washable, which again is good news, if you plan on working out in the thing. This is due in part to the fact that the box -- the brains of the operation -- is removable. This also means that you can use a single box to plug into different garments, which could include things like workout pants in the future.%Gallery-158046%
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.
Squid is a shirt that keeps an exercise journal so you don't have to
Wearable fitness trackers are everywhere these days. Everyone has a GPS watch, companies like Jawbone have turned to slightly stranger form factors, while AT&T and Under Armour are putting sensors inside clothing. Students at Northeastern University think the latter have the right idea, and have put an array of electrodes inside a compression shirt. The apparel is part of system being called Squid, which also includes a smartphone app and an exercise tracking site. Unlike other tech that ends with monitoring hear rate and tracking GPS coordinates Squid can actually gauge muscle activity and count reps so you don't have to. The shirt probably can't tell the difference between a bench press and push up, but at least its one less task to worry about while whipping yourself into fighting shape. No word on if or when the system might become available to the general public, so you'll have to make do with the video after the break to see it in action.
Robot dragon teaches kids language skills, battles impulse to terrorize city
Did you have trouble learning language skills at a young age? It's probably because you didn't have the right teacher. And by "the right teacher," we mean the right robotic dragon, naturally. This cuddly little mythical beast is the joint creation of researchers at Northeastern University, MIT and Harvard -- some of whom were behind the decidedly creepier Nexi bot. It's part of a National Science Foundation-funded program to help young children learn language skills, suggesting that forming a bond with a teacher plays an important role in the educational process. The dragon will be brought to preschool classes to help test out this hypothesis. Hopefully a robotic knight will also be on-hand, just in case.
iPhone reads blood glucose level with nanosensor tattoo (Updated)
For diabetics, checking blood glucose levels is literally a pain. Current blood glucose meters require a prick of the finger to get a small blood sample that is then put onto a small paper strip, inserted into the meter, and analyzed. The strips are a recurring cost to diabetics, and the constant finger pricks can be a route for infection. Now a research team at Northeastern University has developed a method of reading blood glucose levels with an iPhone and a nanosensor tattoo. The team's method works this way: they inject a patient with subdermal nanoparticles containing "fluorescent dye, specialized sensor molecules...and a charge-neutralizing molecule." The molecules attach to glucose, release ions, and alter the glow of the nanosensor tattoo based on the relative amount of glucose. While the initial device for reading the tattoo's glow was a big ugly box, one of the team members apparently outfitted an iPhone case with LEDs and filters to do the job. According to our sister site Engadget, the team is also looking at a way to measure blood sodium (associated with dehydration) and oxygen levels with iPhones and apps. You never thought that your iPhone would be an early-generation medical tricorder, did you? Update: Since a few commenters asked, this is an experimental device and has not (to our knowledge) been submitted to the FDA for their lengthy approval process.
Fluorescent nanosensor tattoo monitors glucose under the iPhone's glare
Unless you're a True Blood diehard, the idea of bleeding yourself intentionally shouldn't really seem all that appealing. So imagine how most diabetics feel when they're forced to prick their fingers seven times a day in the name of health. Well, soon they might not have to thanks to a nanosensor tattoo and... an iPhone? Developed by Prof. Heather Clark and her Northeastern University team, this injection of subdermal nanoparticles combines "fluorescent dye, specialized sensor molecules...and a charge-neutralizing molecule" that attach to glucose, releasing ions and altering the tat's glow in the process. The researchers had originally designed a "large boxlike" tattoo-reading device, but an apparent Apple fanboy on the team modded an iPhone case with LEDs and a filter lens to make the whole affair a bit more stylish. Next up for the team is, you guessed it, an app for that -- although this one'll focus on sodium.
Northeastern University students build web-syncing, home-automating DPAC alarm clock
It may not actually be available for sale, but it looks like some students from Northeastern University are giving devices like the Chumby and Sony Dash a run for their money. They've built this so-called Dynamically Programmable Alarm Clock, or DPAC, which can sync up with your Google Calendar to automatically set alarms, get traffic, weather and other information, and even integrate with a home automation system to turn on the lights, open the blinds, and start your coffee maker as part of a wake-up cycle. What's more, the whole thing can also be configured using a web interface, and it of course packs a built-in FM radio and an iPod dock for good measure. Hit up the source link below for a look at the months-long build process, and head on past the break to check it out in action.
Students build 3D computer interface using copper, felt, and lots of moxie
Always on the lookout for bigger and better ways to faux-scratch a record with your PC, these students at Northeastern University have developed a human-computer interface that utilizes copper pads and our beloved theory of electrostatics. This little devil is able to track the position of a user's hand in three dimensions, without attaching markers to the body or requiring the user to hold some sort of controller. We can think of a couple theremin players that would love to get their hands on one of these things (Mike Love, we're looking at you). But don't take out word for it -- peep the video below to groove along with these dudes as they literally rock the (virtual) bells, play some organ, and even do a little fingerpainting.
Physicists develop microlens with earth-shatteringly short focal length
It's hard to say when we, the consumers, will actually see any real benefit from the latest noteworthy discovery from Northeastern University, but we can only imagine that Srinivas Sridhar and team aren't wasting any time moving things forward. Said crew has recently created a "new microlens that focuses infrared light at telecommunication frequencies," and if you're looking for specifics, it can focus an infrared beam to a spot just 12-micrometers away from the surface. The science behind the discovery is probably only digestible by those that understand rocket science, but the long of short of it is this: the "research shows that it is possible to create smaller, ultra-compact infrared optical components that can be integrated into existing semiconductor technologies while not sacrificing image quality." Now that's something even the layman can appreciate. [Via Physorg]
