Design and Fabricate of Reconnaissance Robots for Nuclear Power Plants that Underwent Accidents

Abstract

This paper presents a robot developed for reconnaissance at a nuclear power plant that had an accident. When an accident occurs, such as the Fukushima Daiichi Nuclear Power Plant disaster, rubble is scattered on the premises, increasing the radiation dose. Consequently, it is nearly impossible for humans to enter the plant and assess the situation. Therefore, a robot that performs reconnaissance is required. In this study, we designed and fabricated a reconnaissance robot to be used in a nuclear power plant that has undergone an accident. The inaccessibility of the scattered on-site rubble and high radiation dose can be addressed by employing an airship-type design that does not use electronic devices.
