  • 본 논문에서는 수중에서 광과광센서를 이용하여 AUV의 도킹스테이션에의 도킹에 대한 새로운 연구를 하였다. 이를 위해 LED를 유도광원으로 사용하는 도킹스테이션과렌즈, 광 변위센서, 신호처리기, 연산처리기로 구성된 센서시스템 무인잠수정에 장착한 무인잠수정의 종단유도장치 시스템을 제안하였다. LED 복사광을 이용해 정밀한 상대각도 측정 정밀도를 얻을 수 있도록 집광렌즈 및 광센서 시스템의 원리해석과 이를 검증하기 위해 집광렌즈와 광센서 시스템을 직접 제작하고 기초실험을 수행하였으며 제작한 광학센서를 이용한 AUV와 도킹시스템을 제작하고 수조에서 기본적인 도킹시험을 수행하여 새로운 도킹 방법으로의 가능성을 검증하였다.

  • The more deeply the researches make progress in ocean researches including the seabed resource investigation or the oceanic ecosystem investigation, the more important the role of UUV gets. In case of study on the deep sea, there are difficulties in telecommunications between AUV and ships, and in data communication and recharging. Therefore, docking is required. In AUV docking system, the AUV should identify the position of docking device and make contact with a certain point of docking device. MOERI (Maritime & Ocean Engineering Research Institute), KORDI has conducted the docking testing on AUV ISIMI in KORDI ocean engineering water tank. As AUV ISIMI approachs the docking device, there is some cases of showing an unstable attitude, because the lights which is on Image Frame are disappeared. So we propose the docking algorithm that is fixing the rudder and stem, if the lights on image frame are reaching the specific area in the Image Frame. Also we propose the new docking device, which has a variety of position and light number. In this paper, we intend to solve the some cases of showing an unstable attitude that were found in the testing, which, first, will be identified the validity via simulation.

  • According to Ocean Korea 21, a basic plan established by the Ministry of Maritime Affairs and Fisheries (MOMAF) of Korea in May 2000, Korea Research Institute of Ships and Ocean Engineering (KRISO) proposed a program for the development of a deep-sea unmanned underwater vehicle (UUV) to explore deep sea for scientific purpose. KRISO has launched a project in May 2001 under the support of MOMAF. The deep-sea unmanned underwater vehicle will be applied to scientific researches in deep-sea as well as in shallow water. For operation of underwater vehicles in shallow water near the Korean Peninsula, a special design is required because of strong tidal current. In addition, MOMAF requires the vehicle to be designed for the purpose of long range survey, a long-term observation, and precise works in a specific area. Thus, KRISO has planned to design the system with the functional combination of both ROV and AUV. This paper presents the design of the deep-sea unmanned underwater vehicle.
