This photo provided by Alireza Ramezani, University of Illinois, shows a Bat Bot, a three-ounce flying robot that they say can be more agile at getting into treacherous places than standard drones. Because it mimics the unique and more flexible way bats fly, this new robot prototype can do a better and safer job getting into disaster sites and scoping out construction zones than those bulky drones with spinning rotors, said the three authors of a study released Wednesday, Feb. 1, 2017, in the journal Science Robotics.
