When we remote control the robot in the Fukushima Daiichi Nuclear Power Station reactor building, in addition to the environmental conditions narrow, stairs, rubble, such as high temperature, high humidity, there is a problem which we have not experienced. One is the radiation resistance of the robotic system, and the other is a matter of remote communication. Robot must be active under a hight radiation in behalf of person, a method that can reduce the exposure a radiation is only shielding. It causes increase of the weight of the robot, shielding worsen the exercise performance of small robot. In addition, thick concrete structures to block reactor building is the failure of the radio communications.
