The study of the deep sea will giant robot crab





Korean Institute of Technology and Oceanography (KIOST) the last two years working on a “Krabstera” – a giant robot crab, which in the very near future will be engaged in the study of the deep sea. His first dive to the bottom of the sea to be held this summer. The main task will be to study the underwater robot faults.

One of the key problems associated with traditional screw, remotely operated vehicles (ROV), as well as a fully autonomous underwater equipment (AUV), is to work with them in bad weather is not very convenient. Another problem is that the screw system often raises the bottom of the sludge, which seriously hampers the operator’s view of the underwater apparatus. To solve these two problems going Bonghuan Jun, a researcher from the KIOST, and his team, which is inspired by the natural structure of crustaceans, has created a six-legged robot crab.

In total, the six-legged robot crab used 30 bendy parts. As with a real live representative underwater fauna, two front claws of the robot have high mobility and can therefore be used as a sort of hands with which the robot will collect at the bottom of the objects of interest and store them in a container located on the front of the machine. For easy operation in low visibility provided by the presence of ten optical cameras and powerful sonar, which will scan the area at a distance of 200 meters around.



A computer simulation, scientists have created a robot body, which will not only protect the internal electronics, but also to stabilize its stability in bad weather conditions and underwater currents. Use of the six claws also beneficial not only for sustainability, but also the duty “Krabstera.”


The front paws grips for research and collection of underwater objects

For about a month, “Krabstera” and the control station will be taken to control water coast of South Korea . Then tap it descend to a depth of 200 meters and even then he will be able to take their first steps in the underwater world. The robot will be challenged to study geological underwater connectors and little-known places .

Scientists say that the robot is able to work well for more than 24 hours to obtain a power cable on the outside, but in the future we plan to make the robot fully autonomous and perhaps even learn to swim. Scientists are now studying the minds of the principles by which frogs, turtles and other species are able to move under water, using their hind legs. In the future, similar to gather and train “Krabstera.”

And the last interesting fact. Creating a “Krabstera” began with the construction of its miniature version, which has been successfully tested.
