A team of South Korean scientists is battling jellyfish with a new robot-- JEROS, short forJellyfish Elimination Robotic Swarm. JEROS can devour nearly 2,000 pounds of jellyfish in an hour. It floats on top of the ocean and has a GPS navigation system to locate the swarms…it then uses its attached pulverizing propellers to turn the jellyfish into goo. And South Korea has a reason to kill. Experts estimate a 300 million dollar loss per year as jellyfish plague the fishingindustry where they clog nets, feed on fish eggs and consume the plankton that fish normally eat.
