vi-RABT improves ankle rehabilitation with virtual reality and robotics
We obviously love our gadgets around here. But, as worked up as we get for things with octa-core processors and 4K displays, what really excites us about technology is its ability to improve people's lives. And while having an endless repository of information at your fingertips 24/7 certainly qualifies, we're more interested in the people working to solve real problems. In the basement of the Egan Research Center at Northeastern University, a group of students are toiling away under the watchful eye and guidance of professor Constantinos Mavroidis to build a rather unique device called the Virtually-Interfaced Robotic Ankle and Balance Trainer -- or vi-RABT. For the better part of a year the team has been working on what started life as a Capstone project. The concept began when Dr. Maureen Holden, from the school's physical therapy department, came to the laboratory with a problem: how can we improve the speed and quality of recovery for stroke patients who have lost strength in their ankles and struggle to stay balanced? %Gallery-185237%
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 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.
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.
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]
