Developed by researchers at the Korean Institute of Ocean Science and Technology (KIOST) and supported by MLTM(Ministry of Land, Transport and Maritime Affairs) of Korea, is to inspect the seabed structure and shipwrecks off the coast of Korea Peninsula. The robot will explore wrecks despite the powerful surge of tidal current.
A test took place at KIOST’s South Sea Research Institute, located in Geoje City, South Korea.
I was very excited, but on the other hand I was nervous during the test. There are many mechanical and electrical parts inside the legs, such as the electrical motors, reduction gears, amplifiers, and interface boards. If even one sealing is faulty, seawater will enter the container which could cause shorts and corrosion. Any single minor problem would require a long time to fix.
