Aerial Sensors Detecting Underwater Robots

Naval applications?

A 'Sunflower' Eye in the Sky

Dartmouth News, Harini Barath, June 30, 2022

Dartmouth College researchers have created Sunflower, an aerial sensor system that uses lasers which enable aerial drones to detect and locate aquatic robots. A flying drone (queen) scans the water with a laser beam; the aquatic robots (workers) have reflectors that bounce the laser light back to the drone, which captures data including their depth and the angle at which the light struck them. Dartmouth's Charles Carver said this allows the queen to compute each worker's position. Tests in a swimming pool with simulated waves and wind showed the drone could pinpoint the robots with centimeter-level accuracy. .... '
