Development of ROV for limestone cave investigation

Abstract

We are developing a compact ROV aimed at surveying survey of Ryusendo cave Underground Lake. Since it is said that the inside of Ryusendo cave is narrow and complicated, and it is said that the total length is 15 km, ROV is small and it is required to be able to search long distances. Therefore, we propose a method of connecting multiple small fuselages connected. In addition, it was found from the field survey that land transportation is necessary, and as a new function, ROV with amphibious thruster was designed. In the lecture, We will present the design of amphibious ROV.
