Shark Robot US Navy Bashny.Net

The device looks and swims like a real fish




The US military continues to emulate the very nature of their design robots. In fact, use the result of hundreds of millions of years of evolution is very logical.

The final result of the implementation of this principle became GhostSwimmer or Silent Nemo, testing which ended last week. This drone swims under water and so similar to the real fish that he can scare unwary swimmer.

Shown robot has a length of five feet and weigh about 45 pounds. It is similar to the size of an adult albacore tuna, but from a distance it can be mistaken for a shark. The robot was created as part of an experiment to study the possibility of borrowing the principles of construction of living organisms to create unmanned underwater vehicles.

Working on a project CRIC (Chief of Naval Operations Rapid Innovation Cell) at a military base JEBLC-FS (Joint Expeditionary Base Little Creek-Fort Story) in Virginia.

Like a real fish, for traffic control and direction of the robot uses its tail. Photos and videos captured ( 1 , 2 ), as GhostSwimmer floats on the surface, but it can and dive to a depth of approximately 90 meters. The robot is able to operate in shallow water 25 cm.

Fish controlled by cable length of 150 m, but may also float itself periodically returning to the surface for communication. The device has a dorsal and pectoral fins.

The robot moves in fish, so it is very difficult to distinguish, or at least separated from the background real marine life. In addition, the sound of the fin is more difficult to fix than the noise of the propeller.

Purpose of the project - reconnaissance and surveillance, as well as a much more peaceful purposes, for example, the study of the state of the body-friendly ships. It is possible that there is a goal to appease activists for animal rights through the transfer of the functions of existing robots programs a > by training dolphins to find underwater mines.

GhostSwimmer - not the first project of the US military, in which borrow principles of the movement of animals. Before him were cheetah Cheetah , which can reach speeds of ≈45 km / h, robot Stickybot , able to climb due to imitation fabrics gecko paws, and cockroach iSprawl, covering 2, 28 meters per second. US Army создают robot bird Maveric.

There is a similar fish and other US government agencies: the Department of Homeland Security is working on BIOSwimmer .

On the cost and the approximate timing of the start of operation GhostSwimmer has not reported.
