The NYTimes has a great piece about the potential ramifications of science's latest breakthrough discoveries: nanotechnology, robotics, geo-engineering. I used to think that just about anything we could develop, would be developed. Articles like this have helped educate me that we do have a choice as a society about where and when we allow science to go. It's an interesting read.

Oh, you’re probably the same way—how often do you find yourself thinking, “I wish monkeys were more terrifying. Sure, they’re all fanged little were-men, with hand-feet and clever brains, but there must be some way that they could be worse.”

Pretty often, huh?

And, when you watch the news, don’t you constantly find yourself musing, “Hmm. The future is looking a little too bright.”

Well, don’t worry, Buzzketeers. The future promises to be just as dark and bewildering as ever, and horrifying cyber-apes are part of it.

“Now, JGordon, it can’t be that bad.”

Hey! Don’t sound so disappointed; it is that bad. Skeptical? Check it out for yourself—Sciencemen and Techladies have trained two macaque monkeys to control huge robotic arms…using their monkey brains!

Macaques have shown their evil little faces on Science Buzz before (murderous enthusiasm and enthusiastic murder), and I don’t think a refresher on robots is at all necessary—because there’s no escaping them.

Robotic limbs are becoming kind of a big deal these days, but even the most advanced of them rely on nerves remaining in a partial limb, or another part of the body entirely; which muscles to activate for a certain function must be relearned, or an operation like gripping with a robotic hand can be linked to a movement like shrugging the shoulders. It’s tricky to do, and it pushes the brain’s flexibility, especially considering that the only feedback the limb gives might be a hot or poking sensation at the connection point (this in place of a real limb’s feedback, like the pressure, friction, or warmth one might feel through their hands or feet).

Wiring a prosthetic (or any robotic device) directly into the brain—as was the case with these monkeys and their robot arms—overcomes some of the problems with existing prosthetic technology, while adding some new challenges.

With electrodes implanted right into the brain, relearning limb function can come much more quickly and naturally (awful little monkeys can do it, after all). A little too quickly, actually—a monkey at Duke University was similarly wired up this winter to make a robot in Japan walk, and the robotic body actually received the signals to walk before the monkey’s actual body did. Limbs wired the same way could be too fast or powerful for the brain to initially cope with. You might, say, run into a wall before your brain has time to create another route for your robo-legs; the speed of the limb action would be faster than the speed of thought.

However, if the prosthetics operated with a “closed neural loop,” that is to say if they could be made to provide natural feedback to the brain (like heat, pressure, strain, etc), scientists think that the brain could adapt much more quickly, and could even learn whole new pathways of motion. So a person wired up in the right way might be able to control a plane, or a nanosized robot directly with their mind. And it wouldn’t be something where you would think about walking forward and the plane would fly forward—you would learn the plane’s movements of flying, feel the flying, and control it as if you were the plane. That sort of things is still a long way off, and unless new technology is invented to sense and input to the brain in another way, it would require having a bunch of electrodes stuck through your skull and into your neurons.

This, of course, is all scientific blah be de blah, and if distracts from the real issue behind the story: cyborg monkeys. Do you know what the monkeys were actually taught to do with their metal limbs? Feed themselves. How horrible. Why not just teach them how to operate guns with their minds, or remove human brains through our nasal passageways?

In time, that too will come to pass. Look forward to it.


Air Jelly

A friend sent me this amazing video. This new air jelly is awesome. I so want one; I don't know what I'd do with it, but it's cool!

A little bit of research shows it's being made by a German company, Festo. Sadly, for me, their website is all in German and I can't read anymore. If anyone can find out more, I'd love to see a full blog on this!

BigDog has been improved. It now carries 340 lbs. on ice, through snow, over obstacles, and can even jump over things.

The Washington Post has given me something new to try not to think about during every waking hour in a recent article on robotic insects and their potential uses as spies.

At recent political events and rallies in New York and Washington there have been several suspiciously similar sightings reported of large, robot-like insects hovering just above the participants, sparking paranoia that the Department of Homeland Security might be using high-tech surveillance tools to spy on American citizens.

That last paragraph was a very long sentence, with at least one extended example of alliteration.

It has also been argued that these are, in fact, sightings of dragonflies. And, as strong as my inherent distrust of governments and insects is, when you compare the number of tiny government robots out there to the number of actual insects, this second theory seems pretty likely. Nonetheless, the Post article offers a pretty interesting look at some of the developing “robobug” technologies out there.

The Defense Department documents at least 100 models of flying robots in use today, ranging in size from something like a small plane to a songbird. The conventional rules of robotics, however, don’t work very well on a smaller scale, so making a robot as tiny as an insect is much more complicated. The CIA developed a four-winged dragonfly-like device as early as the 70s, which flew under the power of a tiny gas engine, but was abandoned due to its inability to cope with crosswinds. Several universities have since created palm-sized fliers, and a team at Harvard got a tiny fly-like robot airborne in July, its tiny, laser-cut wings flapping at 120 beats per second. It weighed only 65 milligrams, but it couldn’t be piloted, and was tethered by a power-supply cord.

Other researchers, funded by the Defense Advanced Research Projects Agency, have directed their efforts towards creating cyborg bugs, inserting microchips into the pupae of moths. The thought is that the nerves of the moths could grow into the chips, and that they could then be controlled and fitted with a tiny camera (or whatever). DARPA also has a similar project with beetles, where the muscles of the insects would generate the energy needed to power the various instruments they could carry. At a symposium in August, a DARPA project manager said of the research, "You might recall that Gandalf the friendly wizard in the recent classic 'Lord of the Rings' used a moth to call in air support. This science fiction vision is within the realm of reality." Even assuming that the DARPA spokesman wasn’t referring to a giant magical eagle when he mentioned “air support,” this is a very funny statement.

There are even rumors that the CIA and other organizations have developed insect robots that exist in your brain and prevent you from being productive by forcing you to think about them constantly. These robots are manufactured and reproduced by your own imagination, and, reportedly, can only be dealt with by chemical abuse and other hobbies.

A wave of human-robot love is sweeping the nation, says a recent Georgia Tech study, with a scale and intensity not seen since the release of Short Circuit 2. And what’s behind this wave of the future, as it crashes on the sunny, unsuspecting beaches of the present? Robotic vacuums. That’s right – little Roombas have crept into the lonely chambers of our hearts, and are sucking them clean.

One can immediately understand some of the attraction to “robovacs”: like a good, “real” friend, they are small, obsessively tidy, and can be purchased. Beki Grinter of Georgia Tech’s College of Computing thinks that the phenomenon goes beyond this, however. Grint began her study when she started seeing online photos of people dressing up their Roombas, and soon found that people were naming the vacuums, taking them on vacation with them, and, in at least one case, introducing them to their parents.

Roomba owners were even modifying their homes to make the Roombas’ “lives” easier; some bought new rugs; some sought out furniture and appliances with higher floor clearance; and some went so far as to pre-clean their floors to make things easier for the Frisbee-shaped robot.

Owners even tolerated Roombas with mechanical failures and functional problems (earlier models tended to break more often), because “they love their robot enough.”

The study seemed to suggest that, among other things, things that are designed to be somewhat emotionally engaging don’t have to as reliable. (This is, coincidentally, one of my mottos.)

One can also infer from the study that the average American family is finally ready to accept robot helpers into their home. Just think: Roomba today, Johnny 5 tomorrow, the Svedka vodka robot the next day… and maybe Roomba again the day after that.

The i-Limb is a robotic hand capable of a wide range of movement, unlike previous mechanical hands, which were generally limited to simple grip and release actions. It is controlled by a series of electrodes placed on the surface of the forearm, with subtle muscle movements activating each of the five motorized fingers.

Each of the fingers is replaceable individually, so, in the case of a wild dog attack or a drunken hammering accident, it would not be necessary to buy an entirely new hand because of a couple mangled i-fingers. This is good news, because the whole device is priced at about $17,000.

For those people who aren’t into the whole robotic hand look, the i-Limb can be fitted with realistic, custom-made skin. For a visual frame of reference, I’d turn the mind’s eye this way. Or just go to the i-Limb’s website.

News items on the i-Limb have yet to address some of the most important issues surrounding the release of bionic limbs, however. For instance, just what level of super-strength can users expect from the device? Are we talking coal-to-diamond squeezing power here, or just single-handed coconut crushing strength? I fully expect this information to be released soon.

The website has some nice videos of the device in action, including footage of the i-Limb being used to tie a necktie, and the i-Limb being used to load a shotgun. Date-night stuff.

There’s also this video, showcasing some of the development processes and testing of the i-Limb. I highly recommend it.


Boston Dynamics has created a robotic four legged pack horse named Big Dog. The Pentagon has given them $10 million in funding. I especially like how it recovers when they give it a big kick.

Popular Mechanics has an interesting article on new robots coming out of Japan. One, called “The Eye,” is designed to roam the streets, identifying and picking up garbage. This will keep our streets and sidewalks clean, without having to pay crews of laborers. (Though I suppose it will increase the demand for highly-skilled maintenance workers to keep the robots in good repair.) They will be used starting next year for cleaning Japanese railway stations.

The other development is a robot that walks, and carries you with it. The ‘i-Foot” is an 8-foot-tall, two-legged robot that carries people from place to place. The driver steers it with a joystick. It can handle rough terrain and stairs that are difficult to cover on wheels. Other companies are also working on walking chairs.

The link above has video footage of the i-Foot.
