"A number of robotic fish are going to be used in an experiment in the port of Gijon in Spain in order to evaluate how effectively and cost-efficiently they can detect water pollution. The carp-shaped robots are part of a three-year research project of Huosheng Hu and his robotics team at the School of Computer Science and Electronic Engineering, University of Essex. The robot fish could be used to inspect rivers, lakes and seas. The life-like creatures, which mimic the undulating movement of real fish, are 1.5 meters (5 feet) long and will be equipped with tiny chemical sensors. These sensors are used to find sources of potentially hazardous pollutants in the water, such as leaks from vessels in the port or underwater pipelines. When they recharge their batteries via a “charging hub” they will be able to transmit the information to the port’s control center. This will enable the authorities to map the source and scale of the pollution virtually in real time."
