チェックバルブを用いたクジラ用投下吸着型ロガーの性能評価

In recent years, zoologists have been used bio-logging approach to study the ecology of wild animals. The bio-logging is a method to record the ecology of animals by attaching a measuring instrument called a logger. Sperm whale is one of the targets. Previous bio-logging studies have revealed some ecological facts about the sperm whales. However, the scene where the sperm whale preys on the giant squid has not been photographed yet. We’re developing a system that uses drones to attach a camera logger to the whale. However, in order to use this system, it is necessary to adsorb logger to the surface of the whale body just by dropping it. To tackle the problem, we proposes a drop-type adsorption logger combining multiple bellows suction cups and original check valves. In this paper, several experiments were conducted to verify the performance of the developed drop-type adsorption logger.
