Robotic Fish To Fight Pollution In Sea

Scientists have designed a robotic fish capable of detecting pollution in water.

Robotic fish: the latest weapon in the fight against water pollution

The life-like creatures, which will mimic the undulating movement of real fish, will be equipped with tiny chemical sensors to find the source of potentially hazardous pollutants in the water, such as leaks from vessels in the port or underwater pipelines.

Thanks to Wi-Fi technology, they will then be able to transmit the information to the port's control centre via a "charging hub" where the fish can charge their batteries. This will enable the authorities to map in real time the source and scale of the pollution (see attached graphic).
