A testing ground is operating for tiny drones that can be deployed in search and rescue missions even in dark, smoky or stormy conditions.
“We all know that when there’s an earthquake or a tsunami, the first thing that goes down is power lines. A lot of times, it’s at night, and you’re not going to wait until the next morning to go and rescue survivors,” said Nitin Sanket, assistant professor of robotics engineering. “So we started looking at nature. Is there a creature in the world which can actually do this?”
Sanket and his students found their answer in bats and the winged mammal’s highly sophisticated ability to echolocate, or navigate via reflected sound. With a National Science Foundation grant, they’re developing small, inexpensive and energy-efficient aerial robots that can be flown where and when current drones can’t operate.
Last month, emergency workers in Pakistan used drones to find people stranded on rooftops by massive floods. In August, a rescue team used a drone to find a California man who got trapped for two days behind a waterfall. And in July, drones helped find a stable route to three mine workers who spent more than 60 hours trapped underground in Canada.
