A fish that finds pollution sends the data of the location to others.
“Each school will contain five fish,and they will constantly monitor for pollutants,”said Dr.Dongbing Gu,who is leading the research.
“When they find something,they will send a message to the rest of the school,who will then gather in the area to take readings.”
The fish move their bodies up and down like waves-driven by motors-and use fins and a tail to change direction.It is hoped they will travel at speeds of up to half a metre per second.
Working models could be available within 18 months.Different sensors will be fitted to hunt for different pollutants (污染物).The data could be used to build a “real time” 3D map of areas of pollution in the water,allowing operators to determine the best way to clean up the area.
The fish will initially be used in ports to monitor leaks from large ships,but Dr.Gu said the same system could be used in the Thames.Researchers hope the robotic fish will be able to spend up to 24 hours in the water before needing to be recharged.
1.The purpose of the robotic fish project is to________.
A.find out whether inbuilt GPS systems are useful

C.prove that robotic fish can be sent into the Thames
