Spain using similar robots that fish made of carbon fiber and iron to reduce pollution in the northern port of Gijon in the country.
Robot fish to use a battery that needs to be replaced every eight hours.
These robots are used to find out if there is contamination in these shallow waters.
“We want to take control of pollution so that if there is someone who dispose of chemicals or something is leaking, we can know it right away,” said Luke Speller, research scientist at BMT Group division, a technology consultant.
“We can find the cause of pollution and direct it,” he added.
The company is part ofa consortium Shoal, theEuropean Commission-funded group that has previously been developed underwater robot.
“At this time, in the ports, therobot is used to take samples once a month,” Speller said.
“If any ship entering the harbor and the resulting leakage of chemicals, it can spread to the coast.”
To change direction
“We put the robot fish in the harbor and we always check the level of pollution,” said Speller.
The robot is called the Fish, with a length of about 1.5 m, made in such a way as to resemble the movement of fish.
Ian Dukes of the University of Essex, other scientists in the consortium, said the inspirationto make this robot came from nature.
He said, “For millions of years, fish have evolved to the hydrodynamic shape, and we try to imitate it with this robot.”
“These robots swim like a fish, and can change direction quickly, even in shallow water though.”
Water pollution is an expensive business. Department of Environment and Rural areas (Defra) UK estimates that in England and Wales alone, the cost to deal with water pollution reached Euro 1.3 billion per year.
Robot fish per unit price of approximately Euro 20,000 (Rp280 million). But Luke Speller said the cost of making this will be reduced if more and more robotic fish produced.
