Students Create $20 Prosthetic Leg -- and It Works!


Now that the technology for advanced prosthetic limbs is achievable, students at Stanford University are trying to make it actually attainable for the average person around the globe.

Students in the school's Biomedical Device Design and Evaluation program started the JaipurKnee Project, and challenged themselves to create a fully-functioning prosthetic leg that could be manufactured for a very low price. Clearly, they were successful, creating the above, fully-functioning appendage for just $20 in parts and production costs.

In order to improve upon the sorts of limbs currently used in developing countries, the team first studied high-end titanium knee joints, which cost anywhere from $10,000 to $100,000. It then explored standard materials found in cheap prosthetics around the globe, and, eventually, came up with the design for a self-lubricating knee joint made from an oil-filled nylon polymer, significantly cutting production costs.

MIT Robot Gardeners Can Grow Tomatoes, But Can't Pick Them


Undergraduate students at the Massachusetts Institute of Technology (MIT) are currently developing a team of robots that they hope will be able to streamline agricultural labor, USA Today reports.

A year ago, Professor Daniela Rus, who heads MIT's Distributed Robotics Lab, challenged her students to build a "distributed robotic garden" during this most recent Fall semester, the second half of their two-semester-long course. By Christmas break, the students were watching with satisfaction as a crew of shin-high, roving robots brought a small garden of cherry tomato plants to life.

Informed by sensors embedded in the plants' soil, the robots are able to automatically deliver fertilizer and water to the tomato plants when necessary. The robots are also equipped with cameras, with which they document each plant's yield, and with software that informs them of how long it typically takes the tomatoes to ripen. Ideally, this technology would enable the robots to nurture and harvest the plants, potentially reducing the need for farm labor and lessening the environmental impact of indiscriminate fertilization. But, as is often the case, the results of the project have not been ideal.

New Material Could Make Robot Muscles Better, Faster, Stronger


There's already been countless advances in the always exciting field of robot muscles, but a team of researchers from the University of Texas have now made what appears to be a considerable leap forward, which they say could allow for "performance characteristics that have not previously been obtained."

The key to that is an entirely new material comprised of ribbons of tangled nanotubes, which can expand its width by 220-percent when a voltage is applied and return to its original shape in just milliseconds when the voltage is removed.

What's more, the material is not only "stronger than steel and stiffer than diamond," but it's able to withstand an extreme range of temperatures from -196 °C to 1538 °C, which could allow robots equipped with the muscles to operate with ease in a wide variety of off-world colonies, er, "harsh environments." Head on past the break for a demonstration of the material in its non-robot form. [Image courtesy NASA Jet Propulsion Laboratory]

Netbook-Based Robot Takes Popcorn Orders via Twitter


In the far-out, sci-fi future of 2009, robots are doing some pretty amazing things, like capturing prowlers, assembling communications networks, and playing Rock / Paper / Scissors. Now, with a little help from RoBe:Do and Twitter, robotics has achieved what may be its crowning achievement: couch-side popcorn delivery. Coppa is a $1,649 software-ready robot (you supply the machine's netbook brain) that arrives with native support for a plethora of languages and tools (including C / C++ / C#, Flash AS3, Java,Microsoft Robotics Studio, .NET, and Visual Basic), and ships with a 12V rechargeable battery, autofocus webcam, and a sonar system. Optional accessories include motion, heat, and humidity sensors, and servo-driven grabbing actuators. The video below shows one such unit that's been programmed to take popcorn orders via-Twitter, timed to deliver the goods when the operator arrives home from work. Couch surfing may never be the same.

Toys of 2009: Robots and Revamped Rubik's Cubes



We spent a week at the 2009 New York Toy Fair a couple of weeks ago and came away with a renewed desire to be ten-years old again. This episode of our Toy Fair series showcases four new high-tech toys:

Ollo Bug Kits: This miniature build-it-yourself kits are meant to introduce kids to simple robotics, but we couldn't resist their charming design aesthetic. These little guys can be found at robotis-shop-en.com and offer a stylish alternative to run-of-the-mill LEGO sets. (Prices vary from $20 up to $100)

Owi Solar Kit and Edge Robot Arm: Owi takes the build-it-yourself robotics a bit further with its diminutive 6-in-1 solar-powered robot kit ($19.95) and A LOT further with its Edge Robotic Arm ($53.95). Connect it to their new USB controller (available in April for $39.95) and program your new mechanical appendage to pour your coffee, or better yet, build the 6-and-1 solar kit for you. (robotikitsdirect.com)

Rubik's TouchCube: Okay, we understand that touch screens are cool but do they really belong on a Rubik's cube? $150 buys you a lot of technology that effectively simulates the experience of playing with the $10 original plastic version. This may have flown in the care-free years of old, but tough-times might make the TouchCube a tough sell. ($150, available in September, rubikstouchcube.com)

(New) Hexbugs: We like the Hexbug (it fought bravely against the Crawling Baby) and the new additions to the lineup add to the fun. The Inchworm gives you limited remote control, and the new Ant scurries around on any surface at three times the speed of the original (prices start at $9.99, hexbug.com).

Navy Report Warns of Robot Uprising



You know, when armchair futurists (and jive talkin' bloggists) make note of some of the scary new tech making the rounds in defense circles these days it's one thing, but when the Doomsday Scenarios come from official channels, that's when we start to get nervous.

According to a report published by the California State Polytechnic University (with data made available by the U.S. Navy's Office of Naval Research) the sheer scope of the military's various AI projects is so vast that it is impossible for anyone to fully understand exactly what's going on. "With hundreds of programmers working on millions of lines of code for a single war robot," says Patrick Lin, the chief compiler of the report, "no one has a clear understanding of what's going on, at a small scale, across the entire code base." And what we don't understand can eventually hunt us down and kill us.

Receptionist Robot Converses With People, Makes Weird Faces



Once again, the Japanese have developed a robot that's smart, creepy, and designed to replace human workers. This time, it's Saya -- a mechanical receptionist that can converse with humans using a vocabulary of 300 words and 700 phrases, and even express emotions via facial expressions.

The idea behind Saya is that she is designed for companies that would like to cut costs without totally sacrificing human interaction. She, or 'it,' depending on your view of robots, is able to guide visitors into an office and talk to them as if she were somewhat real. Why this can't be done with some sort of interactive map is unknown, but hey, it's certainly a step forward.

Saya's main shortcoming, aside from not being able to answer phones and take messages, lies in her creepy facial expressions, which are created by the movement of 18 plates under her synthetic skin. The Daily Mail says "disgust" looks just like "sadness," and her "anger" face "makes her look like she's having digestive issues." Gross.

It's a long ways off, but we're sure some slimeball executives will someday weigh the pros and cons of having to get their own coffee, but never having to worry about a sexual harassment lawsuit. [From: The Daily Mail]

Recycled Citron Parts Built Into Fire-Breathing Robo-Dog



There's something about fire-breathing robots that just gets us giddy, so you can imagine our joy when finding one that gallops, too. The hand-built robot dog -- cutely coined LRRY-1 (pronounced Larry, we'll have you know) -- was built almost entirely from unwanted Citroën scraps, and not a single ounce of non-recycled material was used in the final construction. No idea if it's technically street legal, but we'd love to see a traffic warden try to get this thing back in its cage. Video is posted after the break.

Guitarist Makes Use of 'Bionic Hand' to Regain Abilities



After suffering a stroke in a hotel room following a US tour with his band, the Long Blondes, guitarist Dorian Cox was left paralyzed down the right side of his body. Even simple movements were made impossible, let alone the ability to play his guitar.

Now he's undergoing neurological physiotherapy, which includes training sessions with a mechanical glove called SaeboFlex, which benefits patients by supporting their wrists and helping them grasp and release objects. Like, you know, a guitar. While there are no promises that he'll be able to play guitar again, he's on the road to recovery, and rocking.

"It's a fantastic service," Cox told the Telegraph. "It's helping tremendously and I think it can work wonders for me and others -- it's almost like a gym for my hand." We've had that thought about other things. Like, you know, beer cans.

Okay, now we really feel lazy. [From: The Telegraph]

Robot Makes Stage Debut in Japanese Play


wakamaru on stage


Continuing their march toward the obliteration of mankind, robots are now learning the art of theater, the BBC reports.

These robotic thespians will take the stage for the first time, at Japan's Osaka University, for the production of 'Hataraku Watashi {I, Worker).' Acting alongside humans, the robots have been programmed to converse and interact with the human actors on stage. Two robotic actors will play the parts of two robotic workers, one of whom strangely comes to dislike work.

The Wakamaru robots, developed for house-sitting and secretarial work by Mitsubishi, were outfitted with software specially designed by the University's theater department.

The play, set in the near future and dealing with questions of technology, humanity, labor and ethics, is currently 20 minutes long. Playwright Oriza Hirata, though, hopes that 'I, Worker' will be shown as a full-length production by 2010.

Although we haven't seen them in action, we are fairly certain that the robots' acting styles are very similar to those of Keanu Reeves. Just a good bit more expressive. [From: BBC]

Robot 'Bible Scribe' Writes Out Good Book in Calligraphic Text




A trio of German artists are currently showing an installation in which a robotic arm transcribes, on scrolls of paper, the entire Bible in calligraphic text, according to Walyou.com.

Entitled 'bios [bible],' the installation aims to "correlate two cultural systems which are fundamental for societies today -- religion and scientific rationalism," according to the artists.

This work certainly has viable context in these days when Bible study groups meet on message boards, and the Good Book itself is available online in its entirety and in every conceivable translation and language.

That being said, Scripture and the avant-garde of technology have been bedfellows for much longer than this installation seems to let on. After all, if it weren't for one German's faith and technological savvy -- nearly six hundred years ago -- some of us would have never held a Bible in our hands. [From: Robotlab.de via Walyou.com]

Recon Scout Robot Gets New Job at Prison



You may remember this little dumbell-looking Recon Scout drone we saw last year, when it had just been implemented in the military. If you'll recall, the robot selflessly allows itself to be thrown into wild and unpredictable situations deemed "too risky" for people, then transmits grainy video back to an Operator Control Unit.

Well, it turns out that the California Department of Corrections and Rehabilitation (CDCR) was interested in this rugged bastion of self-sacrifice, too. The CDCR can apparently envision all kinds of nightmare scenarios in which prisoners have weapons and no human wants any part of it -- which is why they've agreed to a rental contract where they get ten devices and developer ReconRobotics gets feedback from the Department in exchange.

Seriously though, aren't there any jubilant tasks we could set this guy to? He's getting to be such a killjoy.

House With Legs Can Walk. Seriously.

Wouldn't it be nice to have a portable home without the stigma attached to RVs? That's sort of, well, not really, the idea behind this walking house, designed by Danish art collective N55 and MIT engineers. The domicile sits on six hydraulic legs that can move at walking pace over any terrain. The legs are controlled by a computer inside the house, each moves independently and three are always on the ground for stability. The point of it all? Floods! If waters level rise, you just stroll away in your house.

The whole pod is about 10- or 11-feet high (different sources had different stats), contains a living room, toilet, bed, and a kitchen with a wood stove. The point of the whole thing is sustainable living, so the house is solar and wind powered. The whole thing costs just under $50,000, but the designers think it can be made for cheaper to gear it towards people on a modest budget. You may laugh, but according to the news, that could be all of us in like a week.

Seriously, though, we really want to know where you're supposed to park this thing, why it's better than an RV (yes, it's all-terrain but it's slow as hell), and does it come in any other colors? We're partial to something a little lighter. Don't miss the video after the break. [Source: The Daily Mail]

30% of US Army to Be Staffed By Robots In 2020

Army Aiming to be One Third Robotic in 12 YearsSure, the failure of shows like 'Robot Wars' to capture the attention of American television viewership has shown that, surprisingly, most Americans just aren't that interested in militant robots. The U.S. Army, however, has some very different inclinations, announcing plans to have 30-percent of its force staffed by robots by 2020, just 12 years from now. That includes vehicles that drive themselves, robot sentries, and even, eventually, bipedal walking cyber-soldiers who as of now exist only

We've reported on many early versions of these future toys, like a little bat-like spy drone and the SWORDS rovers that were deployed in Iraq and then later removed due to supposed "control issues."There was also the time last year when a robotic cannon went crazy and killed nine, something we hope doesn't become a more common-place occurrence with this initiative.
