Mini robot fish swim in schools, just like the real thing – Japan Today

Inspired by how schools of fish intuitively synchronize their movements, Harvard scientists have engineered miniature underwater robots capable of forming autonomous swarms.
Each robotic fish, known as a “Bluebot,” is equipped with cameras and blue LED lights that sense the direction and distance of others inside water tanks.
They swim using flapping fins rather than propellers, which improves their efficiency and maneuverability compared to standard underwater drones.
“It’s definitely useful for…
