US Navy unveils robotvis




The US Navy has recently demonstrated a robotvis which should be used for various studies from next year. The structure is about 1.5 meters long, weighs 45 kilograms and can be used up to 90 meters below the surface.

The robotvis must be by way of moving distinguished. Where such structures are often driven by propellers, called Ghost Wimmer can by natural body movements move in a more realistic way through the water. The robotvis can therefore move almost silently through the water and is also less visible for a sonar, as writes The Virginian-Pilot.

Ghost Wimmer is about 1.5 meters long and weighs about 45 kilograms. With these dimensions, the drone is compared with a tuna. The robot can be controlled with a remote controller, but the Navy can also program the structure. The fish can therefore own power through the water swimming. This can to a depth of about 90 meters, thus The US Navy can use these robots to explore ports or to explore enemy territory. In addition, the state of a sea mine, or the hull of a vessel can be examined. Human divers need is therefore unable to go more in dangerous situations.

The project is part of the Silent Nemo program. The robot has been developed by the Office of Naval Research. It currently goes to a demonstration model, but the Ghost Wimmer should be operational within a year.
