این ماهی رباتیک در آب شناور شده و با نمونه گیری از آب دریا در صورت برخورد با آلودگی ها و لکه های نفتی، موارد رو به پایگاهی در خشکی مخابره میکنه. و جالب اینکه حتی میتونه محل منبع آلودگی رو پیدا کنه.

از این ماهی به زودی قراره که در بنادر اروپایی استفاده بشه.

ROBOTIC FISH might soon be patrolling Europe's harbours

This robotic fish is to detect pollution in Spanish ports

Funded by the European Union, the trials are designed to find out if the autonomous swimming machines can detect harbour contamination and, in some cases, trace it to its source.

The approximately 1.5m long carbon fibre and metal robots look and swim like fish, and they sample the water constantly, periodically relaying findings to shore. Constant water sampling is one of the major goals, since harbours presently take samples only about once a month according to Luke Speller, a senior scientist at consortium member BMT consultancy.

"The idea is that we will use robot fish, which are in the harbour all of the time, and constantly checking for pollution," he said.

Ian Dukes of Essex University, another consortium member, said that the fish design is a natural fit for the robotic harbour sleuths. He explained, "Over millions of years, fish have evolved the ultimate hydrodynamic shape, and we have tried to mimic that in the robot.

"They swim just like fish; they are really quite agile and can change direction quickly, even in shallow water."

The robotic fish also don't get tangled up or clogged by weeds as easily as other designs that use propellers or thrusters.
