Rather than sending divers into the Pacific to check for contaminants leaking from Fukushima, it would be great if we had an undersea robot that could safely do such a job. The SHOAL Robotic Fish may be exactly the solution the Japanese government has been looking for.
Created by scientists at Great Britain's Essex University, the robot fish is completely waterproof and swims through the water with amazingly accurate fish-like movements. Equipped with pollution detecting instruments and a WiFi module that sends the data back to its user, the robot will be available for about $29,000.
You can see the robotic fish in action in the video below.
