South Korea Develops Jellyfish Shredding Robots

October 7, 2013


Because apparently jellyfish are becoming a serious problem, South Korea has developed a swarm of aquatic robots designed to detect and "pulverize" jellyfish using spinning propellers. When reached for comment, Poseidon had this to say, "NOW YOU GONNA PAY, HUMANS!" before stabbing my intern with his trident to attract sharks. Now I need a new intern.

Known as the Jellyfish Elimination Robotic Swarm (or JEROS) the sea-bound robots use a combined GPS and camera system to detect jellyfish before catching them in nets.

"Once caught, the jellyfish are pulverized using a special propeller,"

The researchers also experimented with arranging their killer ' bots into swarms, with a video showing a group of three individuals controlled as one.

The team has been led by Professor Myung Hyun, who has been working in response to the growing danger to businesses and individuals from swarms - or blooms, as they are technically known - of jellyfish.

Writing in the journal of Advances in Intelligent Systems and Computing , Hyun describes jellyfish as "a great menace to the oceans ecosystem, which leads to drastic damage to the fishery industries.

There's a video of a jellyfish getting "pulverized" after the jump, but it's kind of graphic. One minute there's a jellyfish, and the next there's like, just a bunch of wispy pieces of jellyfish. You'd think there would be a better way, but what do I know? "Dick jokes and dinosaurs." That was meant to be rhetorical.

Keep going for the video in case you ever wondered what a jellyfish in a blender would look like.

Thanks to Lavious, who agrees if you think a jellyfish shredding robot is going to spare you if you got caught in its net you're dead wrong.

  • Not very well thought out...the speculations about the jellyfish debris are spot on. I'm certain there is an ecological imbalance that nature needs to address here. No disrespect to the scientists. However, it seems to be the same pattern of not really looking at the source of the problem to get a real fix. They seem to be creating a bigger problem. The consensus here shows that, as well. Duh?!

    Sooooo...the jellyfish that are out there on their own, naturally, are the menace to the ecosystem? Monster blooms have been around since way way way before man. Also, giant ships have been cripple by them for a century, so this is hardly a new, man-made phenomenon. To say that the jellyfish blooms are the unnatural part, then immediately reference the human fishing industry is quite stupid. I hope that scientist gets stung. Not to death because that's a bit harsh, but enough that he pees a little every time he sees a gelatinous blob.

  • Ha Ha Ha Ha Ha8-)

  • After reading about some of the issues we have with blooms along coasts, of jellyfish and other sea life, this might not be a bad idea.

    The blooms themselves are actually responses to human changes elsewhere so I'm sure there's no harm in fixing an issue we introduced (see the cane toad).

    The machine they "developed" seems to be two boat propellers next to each other. Not exactly what I'd call a marvel of engineering.

    I can't wait to see this video used in a North Korean propaganda video. Something about trained jellyfish attaching enemy submarines I hope.

    Not to worry. Once this thing dices a few dolphins, Greenpeace will have a cow and they'll shut them down.

    It doesn't seems very fast. Only slow brainless jellyfish would be caught by that. But I bet that trash can easily clog it.

  • Closet Nerd

    Where do we send our resumes to be your next intern?!

  • Matt D

    some animals were harmed in the making of this film

    I'm pretty much anti-jellyfish, so this is kinda cool. But I'd also be okay if some South Korean scientists developed robot-shredding jellyfish, not gonna lie.

  • So instead of full sized jellyfish that would sting you, there is now jellyfish soup that will still have stinging particles floating around that could potentially sting you anyhow?

    Maybe they don't know this but tentacles that become separated from the jellyfish can still sting so this is an incredibly bad idea.

  • disqus_k2QxOV9H7Z

    I don't think they are worried with that. They want to reduce their numbers because jellyfish blooms harm the fishing industry.

    But some say that shredded jellyfish releases substances that stimulate their colleagues to reproduce, if that is true them it is still a bad idea.

    I think they should promote them as food instead.

  • bigalosu

    These were both immediately what I thought. The nematocysts are still active and some species do release chemicals that promote reproduction when destroyed.

    I think it is also because of situations like this:

  • cruel... stop the killing robots now!!!

  • baal

    Kill the killing robots!
