You can write your own connective gag for these two links

Via Hack-A-Day, the oddballs at Backyard Brains demonstrate a prototype technoexoskeletal assembly for the remote control of insect pests on the move. Shorter version: RoboRoach!


And via Kyle Munkittrick, (software) RoboLawyers:

The most basic linguistic approach uses specific search words to find and sort relevant documents. More advanced programs filter documents through a large web of word and phrase definitions. A user who types “dog” will also find documents that mention “man’s best friend” and even the notion of a “walk.”

The sociological approach adds an inferential layer of analysis, mimicking the deductive powers of a human Sherlock Holmes. Engineers and linguists at Cataphora, an information-sifting company based in Silicon Valley, have their software mine documents for the activities and interactions of people — who did what when, and who talks to whom. The software seeks to visualize chains of events. It identifies discussions that might have taken place across e-mail, instant messages and telephone calls.

Then the computer pounces, so to speak, capturing “digital anomalies” that white-collar criminals often create in trying to hide their activities.

For example, it finds “call me” moments — those incidents when an employee decides to hide a particular action by having a private conversation. This usually involves switching media, perhaps from an e-mail conversation to instant messaging, telephone or even a face-to-face encounter.

I should probably stop being so publicly disparaging about the legal industries, really, lest these expert systems crawl all my online witterings and decide to set me up for a fall…

Cyborg bugs and locust flight simulators

Paul Raven @ 28-09-2009

We seem to be on an insect tip here at the moment, so entomophobes may want to click away until tomorrow. This stuff’s even creepier than software ants, too – via (and many other places) comes video footage of the Pentagon’s latest experiments toward remote-controlling the flight of beetles with embedded hardware:

That’s more than a little unsettling, and I’m not usually bothered by insects. More details over at Wired‘s Danger Room blog.

But why build hardware into fragile real bugs when you could just build fully robotic critters? Obviously you’ll need to suss out the mechanics of their ability to fly, first… so you’re going to need a locust flight simulator like the one developed by a fellow called Adrian Thomas.

The simulator could be a big step forward for the many teams around the world who are designing robotic insects, mainly for military purposes, though Thomas expects them to have a massive role as toys, too. “Imagine sitting in your living room doing aerial combat with radio-controlled dragonflies. Everybody would love that,” he says.

Hmm. I think most folk would far prefer to have all insect combat confined to entirely virtual spaces, at least within the home. And by the time these proposed toy insects make it to the marketplace, you probably won’t need to actually pilot them yourself – after all, you can already build your own self-piloting and fully autonomous GPS-enabled UAV without needing access to a Pentagon-sized budget.

Swarming to it

Tom James @ 28-08-2009

iswarm4One of my favourite[1] plausible science fictional tropes is that of tiny robotic insects. The latest step towards their instantiation has been taken by researchers in Sweden, Spain, Germany, Italy, and Switzerland as they put forward their conception of how swarms of mass-produced robotic fleas could be used for surveillance, cleaning, and medical applications:

The technique involves integrating an entire robot – with communication, locomotion, energy storage, and electronics – in different modules on a single circuit board.

In the past, the single-chip robot concept has presented significant limitations in design and manufacturing. However, instead of using solder to mount electrical components on a printed circuit board as in the conventional method, the researchers use conductive adhesive to attach the components to a double-sided flexible printed circuit board using surface mount technology.

The circuit board is then folded to create a three-dimensional robot.

I can imagine that once this sort of technology matures it will herald a profound change for society. An Orwellian Panopticon where everyone and everything is traced and followed and tracked will become a practicable possibility. Privacy will become one of the most valuable commodities on the planet, with the richest and most powerful people cowering in enclaves sterilized against micro-invaders.

[1]: In that I enjoy them as part of a story and am not entirely ambivalent to their actuality.

Smallest ever free-flying device

Tom James @ 17-08-2009

smallest-uavThe world’s smallest free-flying device has successfully flown. The DARPA-commissioned nano-air-vehicle flew TK without external support:

Aeronvironment has released a video that shows its “nano air vehicle” (NAV), which is the size of a small bird or large insect, hovering indoors without such crutches and under radio control. “It is capable of climbing and descending vertically, flying sideways left and right, as well as forward and backward, under remote control,” says the company….
Their ultimate ask is a ten-gram aircraft with a 7.5cm wingspan, which can carry a camera and explore caves and other potential hiding places. “It will need to fly at 10 metres per second and withstand 2.5-metre-per-second gusts of wind”

The micro-ornithopter/robot-insect concept has plenty of precedants in science fiction, and is another example of engineers borrowing from nature to solve engineering problems.

Re-engineering biology

Tom James @ 31-07-2009

roboticsinsiAs I’ve mentioned before, we’re entering a new phase of technological progress: engineers and technologists are not just seeking inspiration in the mechanisms of the natural world, but are actually reverse- and re-engineering biology to improve synthetic technology. In this case researchers in Germany are studying how bow flies perform their incredible feats of aerial acrobatics by creating a wind tunnel for blow flies (pictured):

A fly’s brain enables the unbelievable – the animal’s easy negotiation of obstacles in rapid flight, split-second reaction to the hand that would catch it, and unerring navigation to the smelly delicacies it lives on.

Yet the fly’s brain is hardly bigger than a pinhead, too small by far to enable the fly’s feats if it functioned exactly the way the human brain does. It must have a simpler and more efficient way of processing images from the eyes into visual perception, and that is a subject of intense interest for robot builders.

While researchers use biomimetic inspiration for the development of flying robots other scientists are working to reprogram existing biological technology, in this case altering bone marrow stem cells so that they function as retinal cells:

University of Florida researchers were able to program bone marrow stem cells to repair damaged retinas in mice, suggesting a potential treatment for one of the most common causes of vision loss in older people.

The success in repairing a damaged layer of retinal cells in mice implies that blood stem cells taken from bone marrow can be programmed to restore a variety of cells and tissues, including ones involved in cardiovascular disorders such as atherosclerosis and coronary artery disease.

For all the pessimism about the future of human civilisation, it is exhilerating to live in an era with so many opportunities and challenges.
