Seoul National University develops inexpensive, super sensitive electronic skin

By - August 13, 2012 2 Pictures
The quest to give robots touch-sensitive artificial skin and develop medical prostheses with a sense of touch has shown much promise in recent years. The latest promising development comes out of Seoul National University's Multiscale Biomimetic Systems Laboratory where researchers have created a new biomimetic “electronic skin” that is inexpensive, yet sensitive enough to “feel” a drop of water.

Glass beads used to mimic butterfly wings

By - May 9, 2012 2 Pictures
Butterfly wing material is somewhat like spider silk, in that they’re both animal-produced substances which scientists are very interested in copying. In the case of butterfly wings, it’s their ability to brilliantly reflect light in a variety of iridescent colors that could prove particularly useful to humans. Researchers from the Korea Advanced Institute of Science and Technology (KAIST) are reporting success in replicating the reflective properties of the insects’ wings, using tiny glass beads. Read More

Robot becomes a leader among fish

By - March 2, 2012 1 Picture
A couple of years ago, a team of scientists from the University of Leeds succeeded in getting live stickleback fish to follow a computer-controlled “Robofish” as it was moved through their aquarium. Part of the reason for the experiment was to learn about fish behavior, in hopes that human interference in their migration routes could be minimized. While the Robofish was simply a plaster model, researchers from the Polytechnic Institute of New York University recently conducted a similar experiment, but using an actual tail-flapping robotic fish. Their discoveries could help save wild fish populations in the event of environmental disasters. Read More

Seeds inspire new artificial anti-fouling surface

By - July 3, 2011 2 Pictures
With marine biofouling on ship hulls increasing drag, which results in an increase in fuel consumption and therefore cost and pollution, the search has been on for a way to prevent fouling that is better than the environmentally damaging, toxic marine paints currently used. Taking inspiration from floating seeds, scientists from the Biomimetics-Innovation-Centre (B-I-C) in Germany have developed a promising new anti-fouling surface that is toxin-free. Read More

Synthetic brain comes a step closer with creation of artificial synapse

By - April 25, 2011 2 Pictures
It's probably still going to be a while before autonomous, self-aware androids are wandering amongst us. That scenario has come a little closer to reality, however, with researchers from the University of Southern California having created a functioning synapse circuit using carbon nanotubes. An artificial version of the connections that allow electrical impulses to pass between neurons in our brains, the circuit could someday be one component of a synthetic brain. Read More

Man-made bee's eye could mean big things for flying robots

By - August 6, 2010 2 Pictures
Day after day, honeybees are able to travel back and forth between a food source and their hive, even in a constantly-changing environment. Given that the insects have relatively small brains, scientists have determined that they rely chiefly on vision and hard-wired visual processing abilities to achieve such a feat. To better understand that process, scientists from the Cognitive Interaction Technology Center of Excellence at Bielefeld University, Germany, have created an artificial honeybee’s eye. Using the device, they hope to unlock the secrets of the insects’ sensing, processing and navigational skills, and apply them to human technology such as micro air vehicles (MAVs). Read More

Fast thinking flies to help build better robots

By - July 13, 2010 2 Pictures
As anyone who has ever tried to swat a fly will know, the little beasties have almost impossibly-fast reflexes. It turns out, in fact, that they have a response time faster than that of any computer. If only we knew what their secret was, perhaps we could develop robots that could react just as quickly. Well, scientists at Germany’s Max Planck Institute of Neurobiology are working on it. Since 1956, a mathematical model has existed that accurately predicts how a fly’s brain will recognize and process visual movements. What hasn’t been understood is how the individual nerve cells interact, to make that recognition and processing possible. Given that a fly’s tiny brain contains over 100,000 nerve cells per cubic millimeter, it would seem impossible to observe the reactions of any one of those cells. That, however, is just what the German scientists have done. Read More

Japanese researchers create artificial butterfly

By - May 20, 2010 1 Picture
Last year, we brought you the story of tech company AeroVironment’s life-size artificial hummingbird, that flies solely by flapping its wings. Now, a group of Japanese researchers has successfully built and flown a flapping-wing-powered swallowtail butterfly. Besides looking incredibly cool, the life-size “ornithopter” has also proven a principle that could have big implications in the field of aerodynamics. Read More

Virtual auto worker will provide data on real-world physical strain

By - May 19, 2010 3 Pictures
He may look like he stepped straight out of Second Life, but he isn’t here to kid around. Santos is a computer-generated auto worker who will perform various tasks on a virtual Ford assembly line, showing real-world researchers how those tasks affect his body. The avatar was originally developed for the US Department of Defense at the University of Iowa as part of the Virtual Soldier Research program where he was used to determine the physical strain that soldiers would experience in a variety of situations. Hmm... auto worker, soldier, university education, muscular, exotic name... perhaps he did just step out of Second Life. Read More
