“…We analyzed the acquired sonar image from the HEMIRE [ 23 , 24 ] remotely operated vehicle (ROV) operation in turbid water in 2010 and the vertical/horizontal image acquired by tripod and pole-mount deployment from the sonar test conducted at the pier of the South Sea Research Institute of KIOST (Korea Institute of Ocean Science and Technology), collected from 3 April to 6 April 2012, to determine the limitations of sonar operation.…”

In this paper, we discuss underwater walking robot technology to improve the quality of raw data in sector-scanning sonar images. We propose a strategy for an efficient and precise sector-scanning sonar image acquisition method for use in shallow, strong tidal water with a curved and sloped seabed environment. We verified the strategy by analyzing images acquired through a sea trial using the sector-scanning sonar installed on the CRABSTER (CR200). Before creating this strategy, an experiment was conducted to acquire the seabed image near a pier using a tripod and vertical pole. To overcome the problems and limitations revealed through image analysis, we established two technical strategies. In conclusion, we were able to achieve those technical strategies by using the CR200, which is resistant to strong current, and its six legs provide freedom of movement, allowing for a good sonar attitude.

“…In future, research and development for integrated comprehensive real-sea experiment processes should be carried out from the point of view of a manager of the wave power test-bed. The KRISO has carried out performance tests on ISiMI 100 (AUV) (Jun et al, 2009), ISiMI 6000 (Lee et al, 2012), Hemire (ROV), and Crabster (ROV) at the SSRI in the aid of various research vessels. Up to two individuals worked to test the relatively small ISiMI 100 weighing approximately 20 kg in the air by using a small fishing boat (Fig.…”

Of late, demand for sites and platforms to test the performance of marine equipment and underwater and surface robots during the development process has been increasing in South Korea. The Korea Research Institute of Ships and Ocean Engineering(KRISO) has performed unit performance and overall performance tests at the Jangmok wharf in Geoje-si, where the South Sea Research Institute (SSRI) of the Korea Institute of Ocean Science and Technology (KIOST) is located, and engaged in the development of a deep-sea remotely operated vehicle (ROV), Hemire, and an autonomous underwater vehicle (AUV), ISiMI 100 (Baek et al., 2008; Jun et al., 2009). Tests for the location estimation performance of underwater vehicles were also performed in the inland environment of Jangseongho in Jeollanam-do (Choi et al., 2019a). Defense industry companies carried out experiments for motion characteristic modeling of AUVs for underwater reconnaissance and hydrodynamic coefficient adjustment and experiments for performance verification in the real sea at the South Sea Research Institute wharf (Park et al., 2015; Lee et al., 2015). Other experiments, mostly for the development performance verification of individual maritime unmanned vehicles, are being carried out in the coastal sea of the Jinhae Naval Academy in Gyeongsangnam-do, the Korea Maritime and Ocean University wharf in Busan, the coastal sea of Pohang, Gyeongcheonho in Mungyeong, and Bangdongho in Daejeon (Jeollabuk-do, 2019). The sites mentioned above need to separately provide facilities required for test preparation, including space for maintenance and repair of test equipment on land including wharf facilities. The need and demand for performance verification in real sea environments is also increasing with the increasing levels of technology and equipment being developed. The Ministry of Maritime Affairs and Fisheries is building a 5 MW
