Have you ever heard robot fish? Scientists will
put some robot fish into the sea near Spain. These robot fish will help people to
detect (探测) the pollution in the
water. If the robot fish are able to finish their work successfully, the scientists
hope to put them into rivers, lakes and seas around the world.
The fish are about 1.5 meters long. There will
be a detector in their bodies. They can find the sources (来源) of pollution in the water, and then the robot fish will eat
part of it. Unlike other robots, they don't need to be controlled by people far
away. The robot fish all have an eight-hour battery (电池). They can "swim" in the sea freely and send back information
to people on the beach. After their batteries die, they will return by themselves.
There are five robot fish altogether now. Each
costs about 29,000 dollars. They are part of a three-year project between engineering
company BMT Group and Essex University in southeastern England.
"We invented the robot fish creatively.
We hope them can find the changes in the sea water and report back the information,"
said Professor Hu of Essex University. His team is developing the fish.
