According to the Korean Advanced Institute of Science and Technology (KAIST), the growing population of jellyfish is causing great harm to the fishing industry. Accidents and fishing losses are adding up to over 300 billion won per year, or roughly 27 billion dollars.
In an effort to fend off swarms of jelly marauders, KAIST has developed autonomous jelly shredding robots. These robots, called JEROS, are floating platforms that can funnel the jellies into their drive propeller, effectively shredding the jellies into so much mincemeat. Not only are they capable of destroying them, they are equipped with a vision system that can locate and target them.
A recent enhancement to the platoon of JAROS units is the ability to swim in formation, allowing for a more efficient mincing of dangerous intruders. KAIST notes that these developmental platforms also hold potential for other uses such as waste detection and removal as well as monitoring oil spills.
