Swimming Robot to investigate Fukushima reactor

Toshiba and researchers from the Japan based International Research Institute for Nuclear Commissioning (IRID) have developed the ‘little sunfish’ swimming robot which will be used to investigate flooded areas of the damaged Fukushima reactor.  The robot is the size of a loaf of bread, weighs 2kg and carries lights, two cameras and a dosimeter to measure radiation. It manoeuvres with tail propellers and connects to a team of scientists via a data cable so that pictures and information can be used to inspect the damaged plant .  Previous robots have got stuck or ‘died’ but everyone hopes that ‘little sunfish’ will have better luck when it’s sent into the reactor this summer.
