Pollutant sniffing robotic fish with sensors and GPS
After humans failing to keep waters clean, polluting them to the core in contrary, some wise hooded scientists from the University of Essex have created a school of robotic fish to monitor the polluted waters. Moving about all autonomously, the pollutant sniffing robotic fish equipped with chemical sensors will swim in seas and rivers recording and then relaying the collected information to the control centers.

Connected with a wireless network (Wi-Fi) to each other, the fish have embedded in them artificial intelligence software which allows for an independent and hinder-free movement all the while. Mimicking a real fish, the robotic fish costing $30,000 each could make expensive baits for the sea predators, unless of course the sensors also impart knowledge to these robotic fish to evade such dangers.
Following the routine completion the robot fish can reach back to its center for charging, with help of an integrated GPS navigation system. To be tested in the river Thames initially, how real help these fish can be, only time will tell.
