Robotic Sea Turtle Scoots Over Sandy Surfaces [Video]
Do you need a robot that can move easily over loose sand, perhaps to serve drinks at your next beach party? Georgia Tech may be able to help you out. Last month, the University debuted a lizard inspired robot that can run over sand. This morning, they're back with another robot designed to scamper adorably across sand dunes, this one inspired by the motion of baby seat turtles. According to the Georgia Tech team, the key to the turtle's speedy movement is all in the wrist.Read on...
Firefly Abdomens Could Be the Key to Brighter LEDs
We may have only come across this because of a Google Alert for news on Firefly, but it's still pretty interesting. Researchers have studied the abdomens of fireflies and what they've found could lead to brighter LEDs. The jagged and scaly layer of the luminescent section of a firefly's exoskeleton helps light better penetrate and shine through, so mimicking that structure in a coating on the outside of current LEDs can increase their light output. Ideally, this news means we're all one step closer to light-up bellies.Read on...
Adhesive Inspired By Mussels Could Glue Blood Vessels Back TogetherI figure it's safe to say that most of us have ended up getting stitches at some point in our lives. Not to imply that y'all are snitches -- stuff just happens, right? If you haven't gotten stitches, please ask your nearest friend who has made their living in a kitchen or on a construction site -- they probably have a story about getting stitches at some point. It's going to sound terrible, and it was definitely worse than it sounds, because getting stitches sucks. The hope for an adhesive solution that lets doctors close wounds without resorting to stitches, staples, or sutures is a lasting one, and researchers at the University of British Columbia appear to have made some headway toward that goal. In a study published today in the journal PNAS Early Edition, the UBC team reports promising findings that the adhesive that mussels use to stick to the rocky shores where they make their home could one day lead to medical glues to reattach and hold together severed blood vessels.Read on...
Squirrels Teach Robots To Lie, Nobody Questions Whether That’s A Good IdeaDisappointed that your Roomba can't clean your house while also telling you that you that shirt your girlfriend hates looks great on you? Researchers at Georgia Tech are working hard to solve that problem by teaching robots to lie, and they're taking lessons in lying from some of nature's most deceptive animals -- squirrels. Because hey, what could possibly go wrong with that plan, which you can see in action below?Read on...
