Abstract

On March 11, 2011, a massive earthquake and tsunami hit Tohoku area, eastern Japan. Since then, the Fukushima Daiichi Nuclear Power Station has been facing a crisis because of loss of all power, and resulting in meltdown accidents. Three reactor buildings were seriously damaged because of hydrogen explosions, and one building was also out of control. It was too dangerous situation for human to inspect inside the buildings because of radioactive material release. To respond to this crisis, we considered using our rescue mobile robots for surveillance missions. Before delivering one of our robots to TEPCO (Tokyo Electric Power Company), we needed to solve some technical issues, such as hardware reliability, communication function, and radiation hardness of the electric components. Furthermore, we needed to add some sensors and functions to respond to this crisis. Therefore, we began a redesign project to equip the robot for disaster response missions. Finally, one of the robots was delivered to the Fukushima Daiichi Nuclear Power Plants on June 20, 2011, and it performed some important missions inside the buildings. In this talk, we will introduce the requirements for the exploration mission in Fukushima Daiichi Nuclear Power Plants, report how we fulfilled them, and report some recent mission results.
