When an active volcano erupts, typically, a restricted area is set around the crater for safety. However, it is important to observe inside of the restricted area for a forecast of disasters, such as debris flow. There are some proposals of visual observation methods in restricted areas, e.g. a tele-operated mobile ground robot with cameras. However, there is no sample-return method for obtaining volcaniclastic materials from such restricted areas. Therefore, in this research, we developed a sample-return device, called strawberry, which was hanging down from a multi-rotor UAV. In this video clip, we introduce our developed devices, and report indoor and outdoor experiments.
