Robot killing jellyfish

South Korean environmental engineers have created robots capable of capturing and destroying jellyfish, after many jellyfish attacked humans and other marine creatures.

JEROS is a device developed by researchers at the Korea Institute for Advanced Agricultural Science and Technology (KAIST), capable of capturing and destroying jellyfish, Discovery News reported.

Myung Hyun, a research professor of robotics, has begun using the human jaw-dropping system three years ago when jellyfish attacks along the southeastern coast of the country were uninterrupted. .

The JEROS robot floats on the water, using both the GPS and the camera to detect jellyfish when they appear. The robots automatically determine the direction and form of the catch. The propulsion system attached to each robot allows them to move in water. The submerged nets will guide the jellyfish towards the robot, where a piece of propeller is used to kill the jellyfish.

Engineers at KAIST said the first robots could kill about 400kg of jellyfish in an hour. Meanwhile the new version of the robot can do the same with 900kg of jellyfish in the same time.

Custard jelly can last nearly 2m. Venom in the tentacles is also one of the most lethal venom in the world. Jellyfish often clog up the water pipes needed for cooling in power plants. A nuclear power plant in Sweden closed on September 30 as a giant jellyfish attack.

Jellyfish cause a great deal of damage to the local fishing industry, where they clog fishing nets, eat fish eggs, and eat plankton that feed on fish.

Jellyfish also kill many marine species. In 2007, a jellyfish attack in Ireland killed as many as 100,000 salmon.
