In recent years, research and development of unmanned aerial vehicles(UAV) has been active, and their use in various fields is attracting attention. However, since UAVs are small and lightweight, they are easily affected by wind. On the other hand, birds can fly with less flapping of their wings by using updrafts. This method of flight is called soaring. At sea, where there is little updraft, albatrosses perform dynamic soaring, flying upwind and gliding downwind with a tailwind, without flapping their wings for long period of time. In this research, aiming at the achievement of a flight robot that enables long-distance flight using a wind like birds, we firstly measured airflow in various directions using multiple flow sensors. Secondly, we estimated the upwind direction from sensor data. Finally, we performed steering control of the flying robot in the upwind direction.
