CRABSTER, CR200, is a multi-legged seabed walking robot
which has been developing in Korea Institute of Ocean Science and Technology (KIOST)
since 2010. CR200 is inspired from legged sea creatures such as crabs and
lobsters so that the appearance and function are similar to that of our inspiration.
Also, the name Crabster originated from adding
crab and lobster together. The most obvious difference between
conventional ROVs and CR200 is the LEGs. CR200 has six legs which allow it to walk
and crawl on sea floor. Furthermore, two hidden
clawlike manipulators inside each front leg give Crabster an ability to work
underwater.
The CR200 measures 2.42 meters long, 2.45 meters wide and
1.3 meters high and the height rise until 1.8 meter at its stand-up position. The
robot weighs 650kg including the payloads and has operable depth of 200 meters.
In order to operate CR200 in underwater, the robot is fitted with Ultra- short
baseline(USBL), acoustic Doppler current profiler(ADCP), several optic cameras,
High resolution scanning sonar, acoustic camera and so on.
