Japanese robot probes Fukushima's nuclear reactor

A Japanese robot has begun probing the radioactive water at Fukushima's nuclear reactor. The marine robot, nicknamed the'little sunfish', is on a mission to study structural damage and find fuel inside the three reactors of the devastated plant. Experts said remote-controlled bots are key to finding fuel at the dangerous site, which has likely melted and been submerged by highly radioactive water.
