Thread:Comments:Japan suggests dumping Fukushima waste at sea as radiation hits lethal levels/Why dont the japanese use robots?

Why don't they use radio controlled robots (something like bomb-squad robots) to perform tasks that would be harmful/deadly to humans to accomplish? The robots could weld and do all kinds of things if they where constructed right. I mean they have built advanced robots like ASIMO before, they should be able to build a custom robot that can do what they need.
