Velociraptor-inspired robot can run almost as fast as DARPA's Cheetah
There's a new robot that's almost matched Cheetah's speed record, but it wasn't designed after another speedy cat. Instead, it takes cues from something more terrifying: a velociraptor. The two-legged machine named Raptor was created by scientists from the Korea Advanced Institute of Science and Technology, who've even outfitted it with a tail like the extinct reptile's for balance. In its current form, it can go as fast as 28.58 mph (46 km/h), just a bit slower than the famous mechanical cat's max speed of 29.2 mph (47 km/h). Compared to DARPA's robotic cat, though, Raptor's technology is a lot simpler, even using ordinary springs as tendons to be able to run fast more effectively. Right now, Raptor's confined to running on a treadmill like Cheetah's older iterations, but its creators hope to make it more stable so it can run on any surface without a tether. Once that happens, all it'll need is a velociraptor suit for the KAIST researchers to start their own (hopefully safer) Jurassic Park.
This tiny generator can power wearable devices using your body heat
Many wearables have decent enough battery life, but you know what'll make them even better? If we never have to recharge them at all. That's why researchers have been developing small power sources that can generate electricity using body heat, including a team from the Korean Advanced Institute of Science and Technology. This particular group has designed a new light and flexible generator made out of thermoelectric (TE) substances printed on glass fabric. It's far from being the first TE generator out there, but it's a huge departure from the usual bulky and rigid ones. As team leader Byung Jin Cho said: This is quite a revolutionary approach to design a generator. In so doing, we were able to significantly reduce the weight of our generator, which is an essential element for wearable electronics.
