Robots, pain, and dance

There was a time many years ago when I knew and interacted with a lot of dancers (mostly in the modern genre) and they often talked about pain. It seems to be a feature of any field where you push your body, e.g., sports, dance, combat, etc. This is somewhat unrelated to the post I’d planned on robots and pain but, this morning I found some information on robots and dance in addition to the previous material on pain and that old memory about dancers and pain popped up out of nowhere.

The article which started this ball rolling in the first place is by Kit Eaton for Fast Company and is titled, Why Robots Are Learning Our Pain Threshold (from the article),

How do you teach a robot how not to hurt humans? Train one to hit someone in an experiment, to find our pain limit. Sounds infinitely sensible, doesn’t it? Until you remember your dystopian sci-fi and consider the implications. [emphasis mine]

The robot experiments are taking place at the lab of Professor Borut Povse in Slovenia. (Yes, he is probably well aware that he sounds like a Bond villain.) He’s been thinking about the future of human-machine interactions, when our daily lives involve working much more closely with robots than we do now. …

Povse spotted a key problem with this scenario: Machines don’t know how much energy in any given impact would result in pain to a person. Or to put it in laymen’s terms, robots don’t know their own strength. Hence he came up with an experiment to solve the problem. Somewhere in Solvenia there’s a robot punching volunteers at a variety of energies, with blunt or sharper “hammers,” so it can work out where the pain threshold is.

The plan is to use the data to inform the design of robots that will operate in close proximity to humans, so that they don’t make sudden movements with too much energy.

As Eaton goes on to note, robots could also be used to hurt/torture in very precise ways that could evade detection. These ethical issues are raised in the article with a suggestion that ethical issues around another ‘robotic programme’, the Predator drone programme (Predator drones are remotely controlled, unmanned planes) have not been handled as well as they could be. Eaton specifically cites an article by Jane Mayer for The New Yorker Magaine (The Predator War; What are the risks of the C.I.A.’s covert drone program?). If you’re interested in these kinds of issues please do read the article. As I don’t want to copy Mayer’s entire piece into this posting I’m going to focus on the pragmatic aspects of the problems  discussed (from the article),

David Kilcullen, a counter-insurgency warfare expert who has advised General David Petraeus in Iraq, has said that the propaganda costs of drone attacks have been disastrously high. Militants have used the drone strikes to denounce the Zardari government—a shaky and unpopular regime—as little more than an American puppet. A study that Kilcullen co-wrote for the Center for New American Security, a think tank, argues, “Every one of these dead non-combatants represents an alienated family, a new revenge feud, and more recruits for a militant movement that has grown exponentially even as drone strikes have increased.” His co-writer, Andrew Exum, a former Army Ranger who has advised General Stanley McChrystal in Afghanistan, told me, “Neither Kilcullen nor I is a fundamentalist—we’re not saying drones are not part of the strategy. But we are saying that right now they are part of the problem. If we use tactics that are killing people’s brothers and sons, not to mention their sisters and wives, we can work at cross-purposes with insuring that the tribal population doesn’t side with the militants. Using the Predator is a tactic, not a strategy.”

Exum says that he’s worried by the remote-control nature of Predator warfare. “As a military person, I put myself in the shoes of someone in FATA”—Pakistan’s Federally Administered Tribal Areas—“and there’s something about pilotless drones that doesn’t strike me as an honorable way of warfare,” he said. [emphasis mine] “As a classics major, I have a classical sense of what it means to be a warrior.” An Iraq combat veteran who helped design much of the military’s doctrine for using unmanned drones also has qualms. He said, “There’s something important about putting your own sons and daughters at risk when you choose to wage war as a nation. We risk losing that flesh-and-blood investment if we go too far down this road.”

It seems to me that from a practical perspective, the use of drones (according to the military strategists quoted in the article) is turning neutral parties into hostile parties at a greater rate than standard warfare tactics would accomplish. At least one of these advisors is also implying that the morale of the parties using the drones is at risk if the means of warfare (the drones) are viewed as less than honourable.

On a possibly less disturbing note, Kit Eaton has another Fast Company article, Robots Dance Their Way Into Uncanny Valley, Next Stop: Your Heart, about a recent demonstration of the HRP-C4 robot. From the article,

Now rewind it, squint a little, and watch again: You’ll almost be able to mistake the ‘bot for one of the real dancers on the stage. Uncanny valley, ladies and gentlemen–HRP4C is busy dancing her way in here, and if the trend continues we can imagine future HRPx units dancing out the other side with a realism and finesse that may even be enough to move you emotionally if you saw them performing live.

Here’s one of the videos available (you can find at least one more on YouTube) but this gives you the best grasp of the ‘uncanny valley’,

For those who like definitions, here’s one for ‘uncanny valley’ from a Wikipedia essay,

The uncanny valley is a hypothesis regarding the field of robotics.[2] The theory holds that when robots and other facsimiles of humans look and act almost like actual humans, it causes a response of revulsion among human observers. The “valley” in question is a dip in a proposed graph of the positivity of human reaction as a function of a robot’s lifelikeness.

I think that’s enough for robots and disturbing thoughts about ethics and ‘uncanny valleys’.

Canada Foundation for Innovation “World’s Best”?; Ping hoodie, clothing that networks socially; life protection clothing; getting spiders to weave building materials?; open access archive for nano papers

The headline for the news release on Marketwire (via the Canadian Science Policy site) is: Canada Foundation for Innovation(CFI) Practices is Called ‘World’s Best’. As it’s been a bit slow for news here I began wondering ‘which practices in which countries are being compared’? After reviewing the reports quickly, I can’t answer the question. There are no bibliographies in any of the three reports related to this KPMG study while the footnotes make reference only to other KPMG and Canadian studies. It was a bit of surprise, I was expecting to see reports from other countries and/or from international organizations and some insight into their analysis as comparing agencies in different countries can be complicated.

I’m not sure how they arrived at their conclusion although they provide some interesting data. From the Overall Evaluation report (p. 28 PDF, p. 24 print),

Exhibit [Table] 4.16 shows that, on average, there have been about 6.4 collaborations with end-users per PL/PU in the past year, three-quarters of which used the CFI projects as key resources, and about 10.2 collaborations per Department Head, about 70% of which using CFI projects in a significant way. For PLs/PUs, there are only small differences in use of CFI projects as a key resource by type of end-user, but Department Heads show more variation in the use of CFI project by type of user; it is unknown if this is significant.

Note that 64% of PL/PUs’ and 80% of Department Heads’ end-user collaborations, respectively, are with Canadian organizations; there is a significant international component (with OMS data suggesting that the CFI projects are a significant attractor for international organizations to collaborate [emphasis mine]).

It certainly seems laudable although I question whether you can conclude that the CFI is a significant international organization attractor by inference alone. Shouldn’t this be backed up with another instrument, such as a questionnaire for a survey/poll of the international organizations, asking why they are collaborating with Canadian scientists? I was not able to find any mention of such a survey or poll taking place.

From everything I hear, Canadians are excellent at academic science research and attracting researchers from around the world and because of our penchant for collaboration we (as they say) “punch above our weight.” I just wish this report did a better job of providing evidence for its assertions about the CFI’s ‘best practices’.

Ping hoodie

Thanks to Adrian Covert’s article on Fast Company, I found information about a prototype for a piece of wearable computing, the Ping hoodie. From Covert’s article,

The Ping clothing concept makes use of embedded electronics and haptics controlled by the Arduino Lilypad system, which transmits to your device (most likely a smartphone) using the Lylipad Xbee. This tech serves as the core interface between you and the information you need. If someone special is sending you a call or text, you can set the hoodie to vibrate in a specific manner, letting you know it’s them. Actions as simple as lifting or dropping the hood can be used to send status updates and messages on Facebook, with the potential to target certain groups of friends.

There’s more at Fast Company or you can check out electricfoxy where the designer, Jennifer Darmour has her site which is where I found this image,

Ping hoodie (wearable computing) designed by Jennifer Darmour at electricfoxy

Do go to Darmour’s site (although Fast Company offers a pretty good selection) if you want to see all the images including close ups of the fabric (don’t forget to scroll horizontally as well as vertically).

Clothing that protects your life

P2i, a company I’ve mentioned here before, has announced a ‘new’ revolutionary form of protective clothing. Actually, it sounds like an improvement rather than a revolutionary concept but maybe I’m getting jaded. From the news item on Nanowerk,

A revolutionary new generation of high-performance body armour, launched today, is lighter, more comfortable and more protective than any previous design, thanks to P2i’s liquid-repellent nano-coating technology.

The new G Tech Vest is a joint development between two world-class UK companies with very strong credentials for the life protection market: P2i, whose technology was originally developed to make soldiers’ protective clothing more effective against chemical attack; and Global Armour, which has been at the leading edge of product innovation in the armour industry for over 30 years.

The G Tech Vest employs brand-new lightweight materials, both in the physical armour itself (a closely-guarded trade secret) and the fabric that forms the armour into a garment. P2i’s technology reduces weight by avoiding the need for bulky durable water repellents and increases comfort by preserving the natural airflow and drape of the garment material.

I recently (April 15, 2010) made a comment about how modern soldiers are beginning to resemble medieval knights and this talk of armour certainly reinforces the impression.

Spiders weaving building materials?

Michael Berger at Nanowerk has written an in-depth article about spider silk and its possible application, amongst others, as a building material. He’s interviewed one of the authors (Markus J. Buehler) of a recent paper that lays out “… a framework for predicting the nanostructure of spider silk using atomistic principles.” More from the Spotlight article on Nanowerk,

In a paper published as the cover article in Applied Physics Letters on April 12, 2010 (“Atomistic model of the spider silk nanostructure”), [Sinan] Keten and Buehler demonstrate an innovative application of replica exchange molecular dynamics simulations on a key spider silk repeating sequence, resulting in the first atomistic level structure of spider silk.

More specifically, the MIT researchers found the formation of beta-sheet structures in poly-Ala rich parts of the structure, the presence of semi-extended GGX domains that form H-bonded 31 helix type structures and a complete lack of alpha-helical conformations in the molecular structures formed by the self-assembly of MaSp1 proteins. These results resolve controversies around the structure of the amorphous domains in silk, by illustrating for the first time that these semi-extended, well-oriented and more sparsely H-bonded structures that resemble 31 helices could be the molecular source of the large semi-crystalline fraction of silks and the so-called ‘pre-stretched’ configuration proposed for these domains.

Shy of reading the original research, which I likely wouldn’t understand easily, Berger’s article provides an excellent entry into the subject.

Open access archive for nano papers

My final item for today is about a project to give free access to papers on nanotechnology that they host and/or publish.  Hooray! It’s very frustrating to get stuck behind paywalls so I’m thrilled that there’s an agency offering free access. From the news item on Nanowerk,

The Nano Archive, the online open-access repository for nanoscience and nanotechnology, invites you to submit research papers to be published free online for users across the globe.

Submitted papers can include peer-reviewed articles, journal articles, review articles, conference and workshop papers, theses and dissertations, book chapters and sections, as well as multimedia and audio-visual materials. The Nano Archive also welcomes new, unpublished research results to be shared with the wider community.

The Nano Archive is part of the ICPC NanoNet project, funded by the EU under FP7. It brings together partners from the EU, Russia, India, China and Africa, and provides wider access to published nanoscience research and opportunities for collaboration between scientists in the EU and International Cooperation Partner Countries.

The Nano Archive currently hosts over 6000 papers. You can read more about the sponsoring agency, the ICPC (International Cooperation Partner Countries) NanoNet here. It has funding for four years and was started in 2008.

Dr. Wei Lu, the memristor, and the cat brain; military surveillance takes a Star Trek: Next Generation turn with a medieval twist; archiving tweets; patents and innovation

Last week I featured the ‘memristor’ story mentioning that much of the latest excitement was set off by Dr. Wei Lu’s work at the University of Michigan (U-M). While HP Labs was the center for much of the interest, it was Dr. Lu’s work (published in Nano Letters which is available behind a paywall) that provoked the renewed interest. Thanks to this news item on Nanowerk, I’ve now found more details about Dr. Lu and his team’s work,

U-M computer engineer Wei Lu has taken a step toward developing this revolutionary type of machine that could be capable of learning and recognizing, as well as making more complex decisions and performing more tasks simultaneously than conventional computers can.

Lu previously built a “memristor,” a device that replaces a traditional transistor and acts like a biological synapse, remembering past voltages it was subjected to. Now, he has demonstrated that this memristor can connect conventional circuits and support a process that is the basis for memory and learning in biological systems.

Here’s where it gets interesting,

In a conventional computer, logic and memory functions are located at different parts of the circuit and each computing unit is only connected to a handful of neighbors in the circuit. As a result, conventional computers execute code in a linear fashion, line by line, Lu said. They are excellent at performing relatively simple tasks with limited variables.

But a brain can perform many operations simultaneously, or in parallel. That’s how we can recognize a face in an instant, but even a supercomputer would take much, much longer and consume much more energy in doing so.

So far, Lu has connected two electronic circuits with one memristor. He has demonstrated that this system is capable of a memory and learning process called “spike timing dependent plasticity.” This type of plasticity refers to the ability of connections between neurons to become stronger based on when they are stimulated in relation to each other. Spike timing dependent plasticity is thought to be the basis for memory and learning in mammalian brains.

“We show that we can use voltage timing to gradually increase or decrease the electrical conductance in this memristor-based system. In our brains, similar changes in synapse conductance essentially give rise to long term memory,” Lu said.

Do visit Nanowerk for the full explanation provided by Dr. Lu, if you’re so inclined. In one of my earlier posts about this I speculated that this work was being funded by DARPA (Defense Advanced Research Projects Agency) which is part of the US Dept. of Defense . Happily, I found this at the end of today’s news item,

Lu said an electronic analog of a cat brain would be able to think intelligently at the cat level. For example, if the task were to find the shortest route from the front door to the sofa in a house full of furniture, and the computer knows only the shape of the sofa, a conventional machine could accomplish this. But if you moved the sofa, it wouldn’t realize the adjustment and find a new path. That’s what engineers hope the cat brain computer would be capable of. The project’s major funder, the Defense Advanced Research Projects Agency [emphasis mine], isn’t interested in sofas. But this illustrates the type of learning the machine is being designed for.

I previously mentioned the story here on April 8, 2010 and provided links that led to other aspects of the story as I and others have covered it.

Military surveillance

Named after a figure in Greek mythology, Argos Panoptes (the sentry with 100 eyes), there are two new applications being announced by researchers in a news item on Azonano,

Researchers are expanding new miniature camera technology for military and security uses so soldiers can track combatants in dark caves or urban alleys, and security officials can unobtrusively identify a subject from an iris scan.

The two new surveillance applications both build on “Panoptes,” a platform technology developed under a project led by Marc Christensen at Southern Methodist University in Dallas. The Department of Defense is funding development of the technology’s first two extension applications with a $1.6 million grant.

The following  image, which accompanies the article at the Southern Methodist University (SMU) website, features an individual who suggests a combination of the Geordi character in Star Trek: The Next Generation with his ‘sensing visor’ and a medieval knight in full armour wearing his helmet with the visor down.

From the article on the SMU site,

“The Panoptes technology is sufficiently mature that it can now leave our lab, and we’re finding lots of applications for it,” said ‘Marc’ Christensen [project leader], an expert in computational imaging and optical interconnections. “This new money will allow us to explore Panoptes’ use for non-cooperative iris recognition systems for Homeland Security and other defense applications. And it will allow us to enhance the camera system to make it capable of active illumination so it can travel into dark places — like caves and urban areas.”

Well, there’s nothing like some non-ccoperative retinal scanning. In fact, you won’t know that the scanning is taking place if they’re successful  with their newest research which suggests the panopticon, a concept from Jeremy Bentham in the 18th century about prison surveillance which takes place without the prisoners being aware of the surveillance (Wikipedia essay here).

Archiving tweets

The US Library of Congress has just announced that it will be saving (archiving) all the ‘tweets’ that have been sent since Twitter launched four years ago. From the news item on physorg.com,

“Library to acquire ENTIRE Twitter archive — ALL public tweets, ever, since March 2006!” the Washington-based library, the world’s largest, announced in a message on its Twitter account at Twitter.com/librarycongress.

“That’s a LOT of tweets, by the way: Twitter processes more than 50 million tweets every day, with the total numbering in the billions,” Matt Raymond of the Library of Congress added in a blog post.

Raymond highlighted the “scholarly and research implications” of acquiring the micro-blogging service’s archive.

He said the messages being archived include the first-ever “tweet,” sent by Twitter co-founder Jack Dorsey, and the one that ran on Barack Obama’s Twitter feed when he was elected president.

Meanwhile, Google made an announcement about another twitter-related development, Google Replay, their real-time search function which will give you data about the specific tweets made on a particular date.  Dave Bruggeman at the Pasco Phronesis blog offers more information and a link to the beta version of Google Replay.

Patents and innovation

I find it interesting that countries and international organizations use the number of patents filed as one indicator for scientific progress while studies indicate that the opposite may be true. This news item on Science Daily strongly suggests that there are some significant problems with the current system. From the news item,

As single-gene tests give way to multi-gene or even whole-genome scans, exclusive patent rights could slow promising new technologies and business models for genetic testing even further, the Duke [Institute for Genome Sciences and Policy] researchers say.

The findings emerge from a series of case studies that examined genetic risk testing for 10 clinical conditions, including breast and colon cancer, cystic fibrosis and hearing loss. …

In seven of the conditions, exclusive licenses have been a source of controversy. But in no case was the holder of exclusive patent rights the first to market with a test.

“That finding suggests that while exclusive licenses have proven valuable for developing drugs and biologics that might not otherwise be developed, in the world of gene testing they are mainly a tool for clearing the field of competition [emphasis mine], and that is a sure-fire way to irritate your customers, both doctors and patients,” said Robert Cook-Deegan, director of the IGSP Center for Genome Ethics, Law & Policy.

This isn’t an argument against the entire patenting system but rather the use of exclusive licenses.

Autonomous algorithms; intelligent windows; pretty nano pictures

I was reminded of watching a printer pumping out page after page after page after page of garbage output because I had activated a process I couldn’t stop when reading Jamais Cascio’s article Autonomy without intelligence? in Fast Company last week.  Cascio describes autonomous software systems operating without human intervention in the finance sector. Called, High-frequency trading (HFT), it relies on networked computers making billions of micro transactions to determine and eventually set the prices. From the Cascio article (an example referenced from a NY Times article by Charles Duhigg here),

Soon, thousands of orders began flooding the markets as high-frequency software went into high gear. Automatic programs began issuing and canceling tiny orders within milliseconds to determine how much the slower traders were willing to pay. The high-frequency computers quickly determined that some investors’ upper limit was $26.40. The price shot to $26.39, and high-frequency programs began offering to sell hundreds of thousands of shares.

The potential for abuse is huge as Cascio points out, exploiting legal loopholes left from “pre-computerized stock trading rules, illegal activities, and systems operating too fast for any human to oversee, let alone counter.” ( For more details about High-frequency trading, read the Cascio and Duhigg articles.)

Cascio then goes on to hypothesize the use of similar networked automatic programs for military purposes. Imagine programs (algorithms) being set into motion and our inability to oversee or counteract them in a military situation? The question hit home again when I found this article (Call for Debate on Killer Robots) by Jason Raimer on the BBC News. Describing one of the impacts of using drone planes that are piloted remotely (sometimes from thousands of miles away),

The rise in technology has not helped in terms of limiting collateral damage, [Professor Noel Sharkey, University of Sheffield] said, because the military intelligence behind attacks was not keeping pace.

Between January 2006 and April 2009, he estimated, 60 such “drone” attacks were carried out in Pakistan. While 14 al-Qaeda were killed, some 687 civilian deaths also occurred, he  said.

That physical distance from the actual theatre of war, he said, led naturally to a far greater concern: the push toward unmanned planes and ground robots that make their decisions without the help of human operators at all.

In fact, the article goes on to reveal that Israel is currently deploying the Harpy, an unmanned aerial vehicle that divebombs radar systems without any human intervention whatsoever. I gather everything is in the algorithms.

I recently came across the word intelligent as applied to windows. It’s a use for the word that contrasts strongly with Cascio’s where he implies that intelligence (in the context of the article cited previously) resides in humans. From the media release on Nanowerk News,

RavenBrick’s patent-pending products use nanotechnology to create an intelligent window filter that automatically blocks solar heat when the outside temperature is too hot, while delivering solar heat inside when the outside temperature is cold. RavenBrick smart-window filters use no electricity, wiring or control systems. They can cut building owners’ energy costs and consumption by as much as 50 percent. What’s more, RavenBrick’s smart-window filters make any interior space more comfortable by managing overheating on hot days, and significantly reduce drafts and cold spots on cold days.

What strikes me most about using the word intelligent to describe these new windows is that I would never have questioned it prior to juxtaposing comments from the Cascio, Duhigg, and Raimer articles. Many times I’ve heard the word intelligent or smart applied to systems or objects without every seriously questioning it. If words are important, than what does applying the word smart or intelligent to a window imply? I’m going to be playing with that one for a while.

To finish off, here’s a link to some pretty nano pictures from the SPmages09 competition which were posted on Nanowerk News. Here’s a sample of what you’ll find,

Nano and the Canadian army and AAAS annual meeting

It turns out that in 2005 the Canadian army commissioned a science fiction writer (Karl Schroeder) to write a book about a future military crisis. Schroeder has included some nanotechnology applications in his future war book, Crisis in Zefra, such as ‘smart dust’. I haven’t read the book yet. Apparently the army has run out of copies but you can get a PDF version from Schroeder’s website here. [ETA Nov. 4, 2014: Scroll down to the second link in the section on Zefra, as the first link no longer works.] Do check out the website blog where he includes some science bits and pieces in his postings. According to the article here, Schroeder has been commissioned to write a sequel. I don’t usually think of the Canadian military as being particularly imaginative so I find this somewhat refreshing (although I may change my mind once I’ve read the book).

The American Association for the Advancement of Science (AAAS) annual meeting (in Chicago this year) has started. There aren’t a huge number of nanotechnology presentations but one which has attracted a great deal of attention is one that focuses on nanotechnology and food. The subject for the panel pretty much guarantees attention will be paid and when you add this title (From Donuts to Drugs: Nano-Biotechnology Evolution or Revolution) you’ve given the media a ready-made title for their pieces. it’s good to see the topic being discussed. If you’re generally interested in this stuff, you can check out a report about it from the Friends of the Earth. The summary (news release) is here and the report is here at the bottom of the page. They are a little bit strident but the material itself is interesting and seems to be well researched. One final comment, the report was released in November 2008 so it’s a little dated.

Nanocoating on fighter planes and a fresh nanotechnology/synthetic biology webcast

There was a big announcement yesterday from Canada’s Minister of Industry,  Jim Prentice, that the federal government was investing $4.6M in R&D for  “next-generation nanotechnology-based coatings for the Joint Strike Fighter (JSF) program.” The JSF is a US-led international programme although I didn’t see mention of any countries other than Canada and the US. There aren’t any specifics about the materials or the science of it all, presumably those would fall under the category of military secrets. You can go here for some general details about the company (Integran) that will be getting the money and the university (Univ. of Toronto) involvement.

I got an invitation for an event that the Project on Emerging Nanotechnologies is holding on Sept. 30, 2008. It’s called  Results of Nanotechnology and Synthetic Biology Public Opinion Poll? The opinion poll is fresh as it was held in August 2008.  You do need to rsvp if you’re planning to attend the live event in Washington or you can view the live webcast without an rsvp. The event will take place from 12:30 to 1:30 pm Eastern Time. I will post about this again closer to the date. On a side note, they still have not managed to reschedule the L’Oreal event where there was going to be a discussion about cosmetics, nanotechnology, risk, and the precautionary principle.
