    Crabster CR200 underwater walking in Ocean Engineering Basin of KRISO

    Published on Apr 5, 2014

    Crabby (Crabster CR200) weighs nearly 700kg with all equipment in air. It is too heavy to walk with tripod gait. So Crabby walks with pentapody or tetrapod gait in air. However, Since Crabby weighs about 200kg in water, it can walk more easily in water. Crabby walks with tripod gait which is fastest static gait of six-legged robot.

    This work was conducted by KRISO with funding from MOF Korea.

    Article "Meet Crabster, the robotic CRAB that could revolutionise underwater exploration and reveal an almost entirely unknown world"

    The Korea Institute of Ocean Science and Technology will test the robot in the Yellow Sea where Crabster will help archaeologists explore shipwrecks
    The 1,400lbs (635kg) robot is designed to scuttle along the sea floor like a real crustacean and can endure strong underwater currents
    Engineers have fitted the mechanical crab with 11 cameras so it can be used in exploration projects and fixing pipelines
