Robots Stop the Jellyfish Invasion

In South Korea, jellyfish are threatening marine ecosystems and are responsible for about US $300 million in damage and losses to fisheries, seaside power plants, and other ocean infrastructure.


Large jellyfish swarms have been drastically increasing over the past decades and have become a problem in many parts of the world. And they aren't affecting just marine life and infrastructure, they can also be harmful to beachgoers.


The robots, called Jellyfish Elimination Robotic Swarm (JEROS), are autonomous, able to use cameras to locate jellyfish near the surface. Once the robots have found a group of jellyfish, they team up and float around in formation.

Together, the JEROS robots can mulch approximately 900 kilograms of jellyfish per hour. Your typical moon jelly might weigh about 150 grams. You can do the math on that (or we can, it's about 6,000 ex-jellyfish per hour), but the upshot is that we're going to need a lot of these robots in order to make an appreciable difference.
