Mister Krabs Has New Competition in Bikini Bottom: Meet Crabster

Nobody really know what is at the bottom of the ocean…and even coastal waters are hard for conventional submarines to search, given the tides and currents they must battle in most places. Well, a new era of undersea exploration may be here, with the crabster CR2000 being released into the ocean  This robot was created by the Korean Institute of Ocean Science and Technology to see if this machine can solve a longstanding mystery.

The body compartment of the Crabster is nearly eight feet long and wide, and just over four feet tall, weighing over half a ton.. The Crabster also rises to over six feet in the air on its legs when it stands up. It’s six legs contains 30 motors which gives the remote pilot ample control and dexterity. The Crabster adapts it’s posture to different current or even pressure conditions to a depth of 200 meters, conditions which are difficult for divers.

The designer of the craft envisions that it could be used for underwater inspection of cables and pipelines, as well as in possible mining or spill clean up.  Using sonar, the Crabster scans the landscape for objects of interest and can relay images through onboard cameras.  Although it is designed as an unmanned robot, it could also be used as a secure base for divers in rough areas.

The Crabster is ongoing final testing in aggressive waters. It’s first mission should be sometime in May in the Yellow Sea looking for ancient artifacts.  Assuming it is successful, this technology could be very useful even in freshwater environments.  There would seem to be obvious applications of this fascinating machine right here in New York, with many wrecks and even a sunken fort to explore right in the Saint Lawrence seaway.
