A robotics engineering professor is building tiny, autonomous flying robots that can use sound waves to navigate in total ...

WPI researchers are enabling aerial robots, smaller than 100 mm and weighing less than 100 g, to navigate without relying on vision.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Bats are well known for their ability to “see” with sound, using ...

Researchers at Worcester Polytechnic Institute are developing tiny drones inspired by bats for search and rescue missions.

Deep underwater and high in the night sky, creatures use sound to see what eyes cannot. Through evolutionary biology and acoustic science, this episode reveals how echolocation emerged in bats, whales ...

Echolocation lets animals use sound as a guide in places where vision fails. They send out clicks, chirps, or taps and interpret the returning echoes to find prey, avoid danger, or move confidently in ...

I said something similar in another article thread recently, but even though the hypothesis was widely expected to be true, it still represents good science to finally get around to testing it and ...

A study published in Diversity provides new insight into how toothed whales and dolphins came to navigate the underwater world using sound waves. Whales and dolphins, which lack external ears, rely on ...

Bats are nocturnal hunters and use echolocation to orientate themselves by emitting high-frequency ultrasonic sounds in rapid succession and evaluating the calls’ reflections. Yet, they have retained ...
