Outline of Final Research Achievements

We have developed an all-weather multi-rotor propulsion robot system that can move in the air, water and under-water as an all-round mobile robot system that can be operated remotely and has high accessibility regardless of the surrounding environment. As a result, we have developed an all-weather quad tilt-rotor multicopter that can be operated in rainy weather and strong winds, attitude control using thrust vectoring technology, and a under-water / air multi-copter that can be maneuvered in air and under-water.
In the future, using the developed robot system, we will carry out inspection surveys on infrastructure structures, such as inspections under part of bridges, disaster investigations such as tunnel collapses, disaster situation investigations at the time of flood, etc.

Academic Significance and Societal Importance of the Research Achievements

強風や雨天でも安全に運用できるマルチコプタは、災害発生時などの緊急事態における迅速な情報収集だけでなく、平時における定期的な情報収集でも役立つ機材である。また、水空両用マルチコプタは、水中機動でダムや堰堤の水中部分の観察・調査も迅速に行えるようになる。特に、推力偏向技術による強風化での安定した飛行や、水中での安定した移動により悪天候での運用も可能であり、迅速な情報収集が実現できる。
