A team of researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a new sprinting robot inspired by a velociraptor. The robot, dubbed the Raptor, runs on two legs, and is capable of running 46 kilometers per hour (kph), or 28 miles per hour (mph), on a treadmill, according to CNET. Raptor can run faster than ...
