Five years ago, a magnitude 9.0 earthquake triggered a massive tsunami that hit the northeastern coast of Japan.
The robots were sent to locate some of the harder-to-reach rods.
But as soon as the robots got close, the radiationdestroyed their wiring.
It is unclear whether a more resistive technology can be developed.
Reactors 2 and 3 are thought to have suffered partial meltdowns.
But Reactor 3 has been a different story.
The radiation levels are much higher and the sensitive electronics and wires inside the robots couldnt handle it.
Unfortunately, a new robot cannot be sent inside to complete the job.
There appear to be no understudies waiting in the wings.
And in fact, a robot capable of withstanding the high levels of radiation environment doesnt exist.
