This Drone Can ‘See’ in Total Darkness Without a Camera Researchers have developed a small autonomous drone inspired by how bats navigate in the dark. Instead of relying on cameras or LiDAR, which often fail in fog, smoke, or low light, this drone uses ultrasound-based echolocation. It sends out tiny sound pulses and listens to the echoes that bounce back from nearby objects. By analyzing these echoes, the drone can estimate the distance and… |
