A bird in the hand thanks to a robot that can perch
Land-bound robots? Been there, done that. Researchers at the University of Illinois at Urbana-Champaign are taking things up a notch with a bird-style bot capable of autonomous flight. By replicating the features that enable birds to make a soft landing -- including the flapping wings that help them change direction -- the researchers developed the first micro aerial vehicle (MAV) capable of swooping down to perch on a human hand. The craft forgoes a vertical tail, which birds also lack, to allow for enough agility to land on a small surface. Articulated wings help the robo-bird complete the maneuver successfully, by first gliding into position and then pitching up and slowing down. Who knew perching was so complicated? Besides just providing a super-nifty party trick for these lucky researchers, the autonomous aircraft could be used in urban surveillance, where a small size would come in handy. Check out the MAV in action, along with the press release, after the break.
T-Hawk UAV enters Fukushima danger zone, returns with video
We'd love to head on down to Fukushima with a DSLR and some iodide pills, but that's obviously not going to happen. Sending in a flying robot seems to be the next best thing, though, and that's exactly what Tokyo Electric Power (TEPCO) has done. T-Hawk, a US-made MAV (Micro Air Vehicle) commonly used to search for roadside bombs in Iraq, made its Japanese debut last week when it photographed the nuclear plant from above, providing a detailed look at the interior damage a month after iRobot's visit. Small enough to fit in a (rather large) backpack, officially the T-Hawk is named for the tarantula hawk wasp species, but could just as easily have been named for the T. Hawk Street Fighter character, who also swoops in to attack his opponents from above. As expected, things look pretty nasty at ground zero, so head past the break for a video of the damage.
NC State gurus build remote control bats, freak out Dukies and Tar Holes
Micro-aerial vehicles, or MAVs as they're called in the elusive underground, are far from new, but a team from NC State University is hoping to advance the field with an all new critter. The Robo-Bat is a remote controlled creature that relies on a super elastic shape-memory metal alloy for the joints, which is said to provide a full range of motion while enabling it to "always return to its original position -- a function performed by many tiny bones, cartilage and tendons in real bats." The crew is also utilizing other "smart materials" in the muscular system, giving it the ability to react in real time to environmental changes such as sudden wind gusts. Ideally, this bionic chiropteran would be used to chivvy those who dare step foot on Franklin Street or inside Cameron Indoor Stadium, but in less malicious situations, it could help well-meaning scientists get the bottom of that whole "aerodynamics" thing.
