Groups of killer robots in Korea seek and destroy what pesky animal?

Answer: Jellyfish

by News Staff / October 8, 2013

Warming seas and overfishing has led to increasing numbers of jellyfish in many oceans around the world. Their large, resilient populations dominate many diminishing fish populations and clog factory cooling systems and battleship condensers. Autonomous robots designed by South Korean scientists travel in swarms, using cameras and GPS to navigate. When the robots detect jellyfish, they capture them with nets and force them through propeller blades, destroying them.
