To help small aerial robots navigate in the dark and other low-visibility environments, my colleagues and I developed an ultrasound-based perception system inspired by bat echolocation. However, ...

Most of us associate echolocation with bats. These amazing creatures are able to chirp at frequencies beyond the limit of our hearing, and they use the reflected sound to map the world around them. It ...

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 ...

Researchers at The University of Western Ontario led an international and multi-disciplinary study that sheds new light on the way that bats echolocate. With echolocation, animals emit sounds and then ...

For years, a small number of people who are blind have used echolocation, by making a clicking sound with their mouths and listening for the reflection of the sound to judge their surroundings. Now, ...

Scientists have figured out why bats crash into buildings: smooth, vertical surfaces like window panes throw off their navigation systems, basically keeping them from “seeing” those obstacles. The ...
