水中ロボットを用いた養殖網清掃システムにおける充電ステーション活用に関する基礎的研究

In aquaculture and fixed-net fishing, fishing nets need to be fixed in the water for a long period of time. Therefore, attached organisms such as shellfish, algae, and parasite eggs easily stick to the nets, making periodic cleaning indispensable. A common method is for divers to dive into the water and clean the nets directly with their hands. However, this method is dangerous because it can be fatal to divers due to high water pressure and low water temperature. Therefore, this study considered the possibility of using underwater robot to clean fishery nets in place of divers to avoid these dangers. A mobile mechanism that can move freely along the sides of fixed fishery net in the water has already been developed in this laboratory. In this study, we propose the cleaning system using autonomous robots that automatically cleans aquaculture nets underwater and the charging station using coils for wireless power supply. This robot and a charging station will be installed on the aquaculture nets, and the robot will be driven periodically to clean the nets underwater with less labor and in a safe manner.
