Synthetic material mimics coral's ocean-cleaning attributes

Humanity's industrial processes have a huge impact on the and, releasing harmful substances such as mercury, arsenic and lead into the water. Chinese researchers are hoping that synthetic coral that mimics the ability of the real thing to collect harmful heavy metals from water could help in the clean up effort, with tests on the effectiveness of the aluminum oxide structure so far showing promising results.Read More

Mussel-inspired surgical glue shuts down bleeding wounds in 60 seconds

The ability of mussels to stubbornly bind themselves to underwater surfaces has intrigued scientists for years. If this ability could be recreated in the lab, it could lead to new adhesives for all kinds of applications. A team of Korean scientists has now developed a surgical glue inspired by these natural wonders that's claimed to be cheaper, more reliable and incur less scarring than existing solutions.Read More

Streamlined shell helps robo-roach slip past obstacles

Besides simply being fascinating to watch, insect-inspired robots may someday find use as scouts in search-and-rescue operations. In order for them to function in such scenarios, however, they'll have to be able to move through fields of debris. While some scientists have looked at using sensors and algorithms that let the bots scan their surroundings and then plot paths around obstacles, researchers at UC Berkley have developed a much less complex but still effective approach – they've outfitted a robotic cockroach with a streamlined shell, that lets it just push its way through.Read More

Pneumatic micro-tentacles can grab delicate objects as small as ants

If you had to grasp a tiny delicate object such as a blood vessel, doing so with traditional tweezers would be a very painstaking process – just a little too much pressure, and the object could be crushed. Instead, scientists from Iowa State University have developed miniature coiling tentacles for doing the job. They're even capable of holding an ant without harming it.Read More

Tough robots keep working even after losing limbs

While robots can be designed to be faster or stronger than animals, it's rare to meet a robot that's as resilient as an animal in the wild after it's been injured. Animals adapt to survive and researchers from France and the US are developing robots that can keep working even after receiving major damage.

MIT's robotic cheetah can now leap over obstacles

The last time we heard from the researchers working on MIT's robotic cheetah project, they had untethered their machine to let it bound freely across the campus lawns. Wireless and with a new spring in its step, the robot hit speeds of 10 mph (16 km/h) and could jump 13 in (33 cm) into the air. The quadrupedal robot has now been given another upgrade in the form of a LIDAR system and special algorithms, allowing it to detect and leap over obstacles in its path.Read More

CoCoRo underwater mini-robots school like fish and share knowledge

Starting in April 2011, the European Union CoCoRo (Collective Cognitive Robots) research consortium has been developing three varieties of autonomous underwater robots that school together like fish. By doing so, the little bots can share and learn from each others' "knowledge" of their environment, acting as a collective cognitive system that's smarter than any one of its individual parts.Read More

VelociRoACH gets a job as an aircraft carrier

In nature, you're not likely to ever see a bird get a piggyback ride from a cockroach and then take off from its back. But in the world of bio-inspired robotics, such things can and do happen. Researchers from the UC Berkeley's Biomimetic Millisystems Lab have successfully demonstrated a cooperative launching system that puts a lightweight ornithopter on the back of its VelociRoACH robotic carpet crawler for a short run before the H2Bird takes to the air.Read More
