There’s a new king crab on the market! The Crabster CR200 is a giant crab-like robot created to explore the ocean floor for ship wreckage and buried treasure. For the last three years, researchers at the Korean Institute of Ocean Science and Technology (KIOST) have worked on this enormous crab, which is about the size and weight of a smart car. The bright red and yellow egg-shaped frame – made from glass and carbon fiber composites – has six fiberglass coated aluminum legs attached. Each leg is six feet in length.
Not only can this crab “claw” its way through the ocean, it can also swim using its hind legs as thrusters – much like a sea turtle. According to Bong-Huan Jun, leader of the research team, the design concept of Crabster is focused on overcoming strong currents and turbid water. “So we looked to the nature of creatures living in similar environments. Crabs and lobsters! CR200 mimics them both,” he said.
The Crabster is equipped with a Doppler radar-based navigation system to guide it through the deep dark ocean waters. There’s also a HD camera on board that’s capable of zooming in on interesting objects. The Crabster’s claws can pick up almost anything and store it in its mouth-like compartment.
