Have you everheard Robot fish? Scientistswill put some robot fishes into the seas nearSpain. These robot fishes will help people detect(探测) the pollution in the water. Ifthe robotfishes are able to finish their work successfully, the team of scientists hopes to putthefishesinto rivers,lakes and seas around the world.
The fishes are about 1.5 meters long and look like carps(鲤鱼). There will be a detector intheir bodies. They canfind the sources of pollutionin the water, and then the robot fisheswilleat part of it. Unlike other robots, they don’t need to be controlled by people faraway. Therobots all have an eight-hour battery. They can “swim” in the sea freely and send backinformation to people on the beach. After their batteries die, they will return by themselves.
There are five robot fishes altogether now.Each costs about 29,000 dollars. They are partof a three-year project between engineering company BMT Group and Essex University insoutheastern England.
“We designed the fishes creatively. We hopethe robot fishes can find the changes in the seawater and report back the information,” said Professor Huof Essex University. His team isdeveloping the fishes.
