テーパ付きローラを用いた旋回式UAV搭載型土砂サンプリングデバイスの開発と評価

抄録

We have developed UAV hanging type sampling device using rotating rollers to realize unmanned and quick sample-return for pyroclastic material. However, the device cannot obtain samples which are at depth of over 15 mm from the earth's surface. Therefore, we aim to improve the sampling depth of the device. In this research, a new method that is rotated the device using tapered rollers has been proposed, developed, and evaluated. As the result of the evaluation, the slight improvement of the sampling depth has been proved.
