Robots get muscular

Robots can be very strong, fast and enduring. However, unlike in animals, none of this strength comes from muscle, instead robots mainly rely on electrical motors and other hard and generally inflexible parts. But with all the advantages that conventional robot hardware can deliver, it still does not match the ability of muscle-powered animals to provide an accurate response to different physical environments. To address this downside of robotics, a group of researchers, led by Professor Rashid Bashir, at the University of Illinois at Urbana-Campaign developed tiny walking bio-robots powered by engineered muscle tissue.

Every year, Telluride, a small mountain town in Colorado, attracts an international roster of scientists from several disciplines for three weeks of intensive discussion and exchange of ideas about neuromorphic engineering, a rapidly expanding research field that promises to bridge the gap between the lifeless silicon of computer chips and the very much lively brain-based biological systems. This year is not an exception: the Telluride workshop is now in full swing and will continue until July 19.

A new European project hopes to make robots more trustworthy

Home_Slide3

Year by year, robots become better and better at negotiating each time more complex social interactions with humans. However, much as their social intelligence has improved, these interactions still suffer from a lack of transparency. In other words, unlike humans, robots are not capable of understanding and explaining their actions in intentional terms, which prevents them from having more effective communication with humans. To the joy of robots and humans alike, this challenge is now addressed by the What You Say Is What You Did (WYSIWYD) project, launched earlier this year.

Car-sized Crabster robot is the new king of the ocean floor

Crabs know their way around the ocean floor. These crawling creatures live in all the waters of the world, so if we want to learn something new about underwater exploration, it might be a good idea to take some cues from them. And this is precisely what a research team at the Korean Institute of Ocean Science and Technology did.

After two years of investigation, the team, led by Bong-Huan Jun, developed Crabster CR 200, a car-sized robot inspired by crustaceans and designed to survey shipwrecks and other areas of scientific interest.

640px-Tetris_OpenerA new breed of micro-robots has been demonstrated to be capable of constructing complex 3D printed tissue architecture by gently guiding diverse cell-encapsulating building blocks, known as hydrogels, to their proper places in multi-layered and heterogeneous tissue structures.

Wings and fins bend…in the same way

1024px-Southern_right_whale_caudal_fin-2_no_skyWhat do a bat, a jellyfish and a humpback whale have in common? For one thing, these animals use their natural propulsors, such as wings, bells and flukes, to move through their environment, be it air or water. Last week a group of researchers published a study in Nature Communications that indicates that these and many other animals from distantly related groups seem to have attended the same school of propulsion. And one of the subjects they studied there was all about being flexible.

Watch these termite-inspired robots in action 

Termites are some of nature’s most magnificent architects that can easily build complex mounds that exceed their own size by several orders of magnitude – occasionally reaching up to nine meters in height. Paradoxically enough, each of these tiny insects does not have even a remote idea of what kind of structure it is building, nor does it receive orders from any termite authority. In fact, the termites’ architectural prowess makes no sense except in the context of swarm intelligence.

1470230_10152443459874676_205650588_nRoboticists from across Europe showcased the most advanced biomimetic robots so far at the Robot SafariEU, an event organized by the Science Museum of London. The Robot SafariEU offered its visitors a special experience with a unique landscape of synthetic creatures able to run very fast like robot cheetah, stretch their wings like the rob-bat, crawl like the robot salamander, swim like a fish or like the robotic turtle U-CAT that is built to explore the deep seas.
