Knifefish Will Execute Dangerous Operations For The U.S. Navy
The U.S. Navy plans to introduce by 2017 robots for different operations, like defending harbors, retrieving sunken equipment and even identifying mines for deactivation. Currently the trained dolphins and sea lions engaged into the Marine Mammal Program are doing this work, but unlike a robot, animals are expensive to train and maintain. Bluefin Robotics has designed the Knifefish, a robot that can operate continuously underwater for up to 16 hours (a usual dolphin stays underwater less than an hour before it needs to breathe). The Knifefish will use sonar to look for mines and could be joined by other bots.
