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.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.
