Judgement Day Update: Artificial Muscles for Robots

artificial-muscle-1It’s a science fiction staple, the android or humanoid robot opens up its insides to reveal a network of gears or brightly-lit cables running underneath. However, as the science behind making androids improves, we are moving farther and farther away from this sci-fi cliche. In fact, thanks to recent advancements, robots in the future may look a lot like us when you strip away their outer layers.

It’s what is known as biomimetics, the science of creating technology that mimics biology. And the latest breakthrough in this field comes from National University of Singapore’s Faculty of Engineering where researchers have developed the world’s first “robotic” muscle. Much like the real thing, this artificial tissue extends to five times its original length, has the potential to lift 80 times its own weight.

???????????????????????In addition to being a first in robotics, this new development is exciting because it resolves a central problem that has plagued robots since their inception. In the 1960s, John W. Campbell Jr, editor of Analog Science Fiction magazine, pointed out this problem when he outlined a scenario where a man is chased across rough country by a mad scientist’s horde of killer robots.

In this scenario, the various models that were chasing the man were stymied by obstacles that the he could easily overcome, such as sinking in mud, jumping over logs, getting around rocks, or tangled up in bushes. In the end, the only robots that were capable of keeping up with him were so light and underpowered that he was able to tear them apart with his bare hands.

robot_muscleThis is a far cry from another science fiction staple, the one which presents robots as powerful automatons that can bend steel girders and carry out immense feats of strength. While some robots certainly can do this, they are extremely heavy and use hydraulics for the heavy lifting. Pound for pound, they’re actually very weak compared to a human, being capable of lifting only half their weight.

Another problem is the fact that robots using gears and motors, pneumatics, or hydraulics lack fine control. They tend to move in jerky motions and have to pause between each move, giving rise to a form of motion that we like to call “the robot”. Basically, it is very difficult to make a robot that is capable of delicate, smooth movements, the kind humans and animals take for granted.

kenshiroFor some time now, scientists and researchers have been looking to biomimetics to achieve the long sought-after dream of smaller, stronger robots that are capable of more refined movements. And taken in tandem with other development – such as the Kenshiro robot developed by roboticists at the University of Tokyo – that time might finally be here.

Developed by a four-person team led by Dr. Adrian Koh – from the NUS Engineering Science Program and Department of Civil and Environmental Engineering – the new artificial muscle is an example of an electroactive polymer. Basically, this is a combination dielectric elastomer and rubber that changes shape when stimulated by an electric field. In this respect, the artificial muscle is much like an organic one, using electrical stimulus to trigger movement.

 

robot-arm-wrestling-03-20-09Robots using artificial muscles would be a far cry from clanking mechanical men. They would be much more lifelike, capable of facial expression and precise, graceful movements. They would also have superhuman strength, yet weigh the same as a person. In addition, the polymer used to fabricate the muscles may have more general applications in machines, such as cranes.

An added bonus of the polymer is that is can convert and store energy, which means it’s possible to design robots that power themselves after charging for only minutes. In a statement released by his department, Dr. Koh highlighted the benefits of the design and what it is capable of doing:

Our novel muscles are not just strong and responsive. Their movements produce a by-product – energy. As the muscles contract and expand, they are capable of converting mechanical energy into electrical energy. Due to the nature of this material, it is capable of packing a large amount of energy in a small package. We calculated that if one were to build an electrical generator from these soft materials, a 10 kg (22 lb) system is capable of producing the same amount of energy of a one-ton electrical turbine.

AI_robotDr. Koh also indicated that robots equipped with these types of muscles “will be able to function in a more human-like manner – and outperform humans in strength.” Theoretically, such polymer-based tissues could extend to ten times their original length and lift up to 500 times its own weight, though the current version isn’t anywhere near that limit just yet.

In the meantime, Dr Koh and his team have applied for a patent for the artificial muscle and are continuing work on it. They predict that within five years they could have a robot arm that is half the size and weight of a human arm, yet could win an arm wrestling match. And the applications are limitless, ranging from robotic servants to search and rescue bots and heavy robot laborers. And let’s not forget that cybernetic arms that boast that kind of increased strength are also likely to become a popular prosthetic and enhancement item.

And for those who are naturally afraid of a future where super-human robots that have the strength to tear us limb from limb are walking among us, let me remind you that we still have Asimov’s “Three Laws of Robotics” to fall back on. Never mind what happened in the terrible movie adaptation, those laws are incontrovertible and will work… I hope!

2013, As Imagined By 1988

bladerunnerTwenty-five years ago, Los Angeles magazine envisioned what the world would look like in the current decade. And unlike Blade Runner, they avoided the cool but standard science fiction allegories – like massive billboards, flying cars and sentient robots – and went straight for the things that seemed entirely possible by contemporary standards.

The cover story of the magazine’s April 3, 1988 edition showed a futuristic downtown L.A. crisscrossed with electrically charged, multi-tiered freeways permeated by self-driving cars. The article itself then imagined a day in the life of the fictional Morrow family of the L.A. suburb Granada Hills, as “profiled” by the magazine in 2013 by science fiction writer Nicole Yorkin.

LAtimes_2013aIronically, the magazine did not envision that it would one day go out of business, or that print media would one day be lurching towards extinction. Nevertheless, the fictional article and the world it detailed were interesting reading. Little wonder then why, earlier this month, the LA Times along with an engineering class at USC, revisited the archives to assess what it predicted correctly versus incorrectly.

Together, pro­fess­or Jerry Lock­en­our and his class made a list of the hits and misses, and what they found paints a very interesting picture of how we predict the future and how its realization so often differs from what we expect. Of the major predictions to be found in LA of the 2013, as well as in the lives of the Morrow family (get it?), here is what they got right:

Smart-Houses:
smart-house_vCe6I_25016In the article, the Morrows are said to begin every morning when their “Smart House” automatically turns on. This consists of all the appliances activating and preparing them breakfast, and no doubt turning on all the environmental controls and opening the shades to get the temperature and ambient lighting just right.

While this isn’t the norm for the American family yet, the past few years have proved a turning point for home devices hooking up with the Internet, to become more programmable and serve our daily needs. And plans are well under way to find a means of networking them all together so they function as one “smart” unit.

Self-Driving Cars:
chevy_env_croppedThe writers of the article predicted that by 2013, cars would come standard with computers that control most of the settings, along with GPS systems for navigation. They also predict self-driving cars, which Google and Chevy are busy working on. In addition to using clean, alternative energy sources, these cars are expected to be able t0 self-drive, much in the same way a pilot puts their plane on auto-pilot. Drivers will also be able to summon the cars to their location, connect wirelessly to the internet, and download apps and updates to keep their software current.

But of course, they got a few things wrong as well. Here they are, the blots on their predictive record:

Homeprinted newspapers:
news_appThe article also predicts that each morning the Morrows would begin their day with a freshly printed newspaper, as rendered by their laser-jet printer. These would be tailor-made, automatically selecting the latest news feeds that would be of most interest to them. What this failed to anticipate was the rise in e-media and the decline of printed media, though hardly anyone would fault them for this. While news has certainly gotten more personal, the use of tablets, ereaders and smartphones is the way the majority of people now read their selected news.

Robot servants and pets:
kenshiro_smallIn what must have seemed like a realistic prediction, but which now comes across as a sci-fi cliche, the Morrows’ home was also supposed to come equipped with a robotic servant that had a southern accent. The family’s son was also greeted every morning by a robot dog that would come to play with him. While we are certainly not there yet, the concept of anthropomorphic robot assistants is becoming more real every day. Consider, for example, the Kenshiro robot (pictured at right), the 3D printed android, or the proposed Roboy, the Swiss-made robotic child. With all of these in the works, a robotic servant or pet doesn’t seem so far-fetched does it?

Summary:
Between these four major predictions and which came to be true, we can see that the future is not such an easy thing to predict. In addition to always being in motion, and subject to acceleration, slowing and sudden changes, the size and shape of it can be very difficult to pin down. No one can say for sure what will be realized and when, or if any of the things we currently take for granted will even be here tomorrow.

For instance, during the 1960’s and 70’s, it was common practice for futurists and scientists to anticipate that the space race, which had culminated with humans setting foot on the moon in 1969, would continue into the future, and that humanity would be seeing manned outposts on the moon by and commercial space flight by 1999. No one at the time could foresee that a more restrictive budget environment, plus numerous disasters and a thawing of the Cold War, would slow things down in that respect.

In addition, most predictions that took place before the 1980’s completely failed to predict the massive revolution caused by miniaturization and the explosion in digital technology. Many futurist outlooks at the time predicted the rise in AI, but took it for granted that computers would still be the size of a desk and require entire rooms dedicated to their processors. The idea of a computer that could fit on top of a desk, let alone on your lap or in the palm of your hand, must have seemed farfetched.

CyberspaceWhat’s more, few could predict the rise of the internet before the late 1980’s, or what the realization of “cyberspace” would even look like. Whereas writer’s like William Gibson not only predicted but coined the term, he and others seemed to think that interfacing with it would be a matter of cool neon-graphics and avatars, not the clean, page and site sort of interface which it came to be.

And even he failed to predict the rise of such things as email, online shopping, social media and the million other ways the internet is tailored to suit the average person and their daily needs. When it comes right down to it, it is not a dangerous domain permeated by freelance hacker “jockeys” and mega-corporations with their hostile counter-intrusion viruses (aka. Black ICE). Nor is it the social utopia promoting open dialogue and learning that men like Bill Gates and Al Gore predicted it would be in the 1990’s. If anything, it is an libertarian economic and social forum that is more democratic and anarchistic than anyone could have ever predicted.

But of course, that’s just one of many predictions that came about that altered how we see things to come. As a whole, the entire thing has come to be known for being full of shocks and surprises, as well as some familiar faces. In short, the future is an open sea, and there’s no telling which way the winds will blow, or what ships will make it to port ahead of others. All we can do is wait and see, and hopefully trust in our abilities to make good decisions along the way. And of course, the occasional retrospective and issue congratulations for the things we managed to get right doesn’t hurt either!

Robots Meet the Fashion Industry

robot_fashionRobotics has come a long way in recent years. Why, just take a look at NASA’s X1 Robotic exoskeleton, the Robonaut, robotaxis and podcars, the mind-controlled EMT robot suit, Stompy the giant robot, Kenshiro and Roboy, and the 3D printed android. I suppose it was only a matter of time before the world of fashion looked at this burgeoning marketplace and said “me too!”

And here are just some of the first attempts to merge the two worlds: First up there’s the robot mannequin, a means of making window shopping more fun for consumers. Known as the MarionetteBot, this automaton has already made several appearances in shops in Japan and can expected to be making debut appearances across Asia, in North America and the EU soon enough!

Check out the video below to see the robot in action. Designed by the Japanese robotics company United Arrows, the mannequin uses a Kinect to capture and help analyze the movements of a person while a motor moves a total of 16 wires to match the person’s pose. Though it is not yet fast or limber enough to perfectly mimic the moves of a person, the technology shows promise, and has provided many a window-shopper with plenty of entertainment!


And next up, there’s the equally impressive FitBot, a shape-shifting mannequin that is capable of emulating thousands of body types. Designed by the British virtual shopping company Fits.Me, the FitBot is designed to help take some of the guesswork out of online shopping, where a good 25% of purchases are regularly returned because they were apparently the wrong size.

But with the FitBots, along with a virtual fitting room, customers will be able to see right away what the clothes will look like on them. The only downside is you will have to know your exact measurements, because that’s what the software will use to adjust the bot’s body. Click here to visit the company’s website and see how the virtual fitting room works, and be sure to check out there video below:


What does the future hold for the fashion industry and high-tech? Well, already customers are able to see what they look like using Augmented Reality technology displays, and can get pictures thanks to tablet and mobile phone apps that can present them with the image before making a purchase. Not only does it take a lot of the legwork out of the process, its much more sanitary as far as trying on clothes is concerned. And in a world where clothing can be printed on site, it would be downright necessary.

The "magic mirror"
The “magic mirror”

But in the case of online shopping, its likely to take the form of a Kinect device in your computer, which scans your body and lets you know what size to get. How cool/lazy would that be? Oh, and as for those AR displays that put you in the clothes you want? They should come with a disclaimer: Objects in mirror are less attractive than they appear!

The Future is Here: Roboy the Robotic Child!

roboy_splashThe field of robotics has been heated up in recent years. With autonomous killing machines being developed by the USAF, mind-controlled prosthesis for the disabled, juggling robots by Disney, a headless Kenshiro Robot and even 3D printable android, it seems like only a matter of time before Asimov’s Three Laws will need to be applied. Either that, or we might have a Robopocalypse on our hands.

But when you see this latest project in robotics, you might find it hard to imagine an apocalyptic scenario resulting. Forget Terminator, this seems more like something from the realm of Pinocchio or AI. That’s the feeling I get from Roboy, a concept that began back in May of 2012 when the University of Zurich’s Artificial Intelligence Lab committed to creating a fully humanoid robot by March of 2013.

For those doing the math, yes, that is roughly nine months. As if his size and proposed aesthetics weren’t enough, the creators even committed to a timeline that mirrored the time it takes to birth and actual child. And just to complete the illusion, they hope to cover the finished product in a soft, artificial skin. Talk about infanto-centric (assuming that’s even a word)!

But of course, the real breakthrough of Roboy is in the design itself, which borrows from the Kenshiro humanoid and the earlier Ecce model that both rely on artificial muscles to move. At this point, the robot is near completion and should be released next month during the Robots on Tour event in Zurich, Switzerland, providing everything arrives on schedule. At the moment, the long-term purpose of Roboy is to act as a prototype for service robots that will help elderly people remain independent for as long as possible.

I smell another movie reference there, one involving and old man and his friendly robot side-kick. Can you guess which one I am referring to here? Correct, it’s Robot and Frank! And with all the developments in robots happening right now, I’d say we need to do our homework and see all these movies, and reread Asimov’s Robot series while were at it!

And while you’re doing that, be sure to check out this video of the Roboy’s design in action:
