Crabster CR200 on-land walking with full fabrication
Published on Apr 1, 2014
Crabstrer CR200 on-land walking with full fabrication before dive into the Ocean Engineering Basin of KRISO, KIOST.
Pentapody, tetrapod, discrete and continuous(wave) gait walking.
This work was funded by Ministry of Oceans and Fisheries (MOF) of R. of Korea
Crabster CR200 manipulation mode with full fabrication(KRISO)
Published on Apr 4, 2014
CR200 has two arms in its forward legs. For underwater manipulation, CR200 supports its body with four legs and deploy its two arms, and push its tool-sled. In this video, the forward arms' motion are replayed 4 times faster than original video.
This work was conducted in Korea Research Institute of Ships & Ocean Engineering (KRISO) by funding of Ministry of Oceans and Fisheries (MOF)
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
