Crabster CR200 underwater walking in Ocean Engineering Basin of KRISO

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.
