The Oceanographic Institute of Science and Technology of Korea (KIOST, for its acronym in English) is preparing for release into the sea Crabster a mechanical crab the size of a car designed to explore the ocean floor in difficult conditions.

The center has more than two years developing this prototype equipped with six-legged autonomous and more than 30 joints. The first prototypes of smaller scale were used to develop balance and drive system.

The traditional submersible vehicles have trouble staying stable in places where underwater currents are strong. On the other hand the drivers tend to lift dirt from the bottom, which impairs vision. Crabster is designed to withstand strong underwater currents, moving steadily at a slow but steady three miles per hour, without picking up sand or mud.

Equipped with a sonar,  with an effective range of 200 meters, and 10 spotlights cameras, Crabster also has two retractable multipurpose clips that hides in its first pair of legs, and a container in which you can save samples.

The vehicle will debut within a month to 200 meters deep. For now, Crabster not completely autonomous. A cable connected to its mother ship provides power and communications. Its creators are now studying how the real crustaceans swim for the vehicle to come off the seabed and move by itself without cables.

เกาหลีใต้เตรียมส่งปูหุ่นยนต์ยักษ์ Crabster ช่วยงานนักประดาน้ำ

วันนี้(23 เม.ย.) สำนักข่าวต่างประเทศ รายงานข่าวเปิดเผยว่า เกาหลีใต้เตรียมส่งหุ่นยนต์ปูยักษ์ชื่อ Crabster CR200 ช่วยนักประดาน้ำปฏิบัติภารกิจค้นหาผู้สูญหายจากเหตุการณ์เรือเซวอล

Crabul-robot a fost creat de cercetatorii sud-coreeni si chiar testat in apele Marii Galbene.

Poate ca spatiul este ultima frontiera, dar sunt destule teritorii neexplorate si in adancuri. In ajutorul celor care vor sa stie mai mult despre ce se afla sub nivelul marii au sarit cei de la institute of Ocean Science and Technology din Coreea de Sud.

“Crabul” este dotat cu 11 camere de luat vederi,…

Designed at the Korean Institute of Ocean Science and Technology (KIOST) with help from five South Korean universities, the Crabster CR200 as its officially known was aimed at overcoming the challenges posed by strong tidal currents in shallow waters. Propellor-equipped ROVs and automatous underwater vehicles are adept at swift movements and deep diving, but the technology doesn’t bode well in rough conditions. Current tidal strengths of 1.5 meters per second are enough to rip the scuba mask off a human explorer, explains Jason Falconer for IEEE Spectrum.

That’s why the KIOST ditched fins with propulsion for a more crustacean approach that allows the robot to walk on the sea floor via six legs interconnected with 30 joints. The resulting structure will kick up less obtrusive debris than standard propellers.
