Inventors from the Korea Advanced Institute of Science and Technology have engineered an unmanned terminator robot designed to control jelly fish population by seeking them out, sucking them up, and shredding them to pieces with propeller blades.

Jellyfish tartare, anyone?

In 2011, Yale Environment 360 reported that over-fishing, declining water quality and rising sea temperatures are likely to blame for massive outbreaks of jellies– which could be the new normal. Jellyfish blooms have been a major problem in northern Asia, specifically, costing the fishing industry in Korea alone $280,000 per year.

The JEROS, or Jellyfish Elimination Robotic Swarm, are programmed to work in formation to scour a defined  area using a camera to pinpoint jellyfish. The bots automatically determine a route and can motor forward or backward and rotate 360-degrees. When groups of jellies are detected they are suctioned in and ground up at a rate of approximately 33 pounds per minute.

While jellyfish are an integral part of a healthy ocean, the relationship between them and fish is complex and an overabundance of jellies can cause a marine ecological meltdown by depleting fish populations. For human activity, not only do an influx of pesky jellies force beach closures but they can easily block cooling intake pipes at coastal power plants and cause full blown nuclear reactor shutdowns, which happened just this week in Sweden.

All of that aside, let’s be real, they sting like hell. And as advanced as some of this ocean technology has come, why are we still peeing on ourselves to stop the pain?
