Not Finding Nemo

Kitted out for "low-visibility intelligence, surveillance, and reconnaissance missions, the Navy's latest unmanned vehicle looks and swims like a large fish.

GhostSwimmer is the latest in a series of science-fiction-turned-reality projects developed by the chief of naval operations' Rapid Innovation Cell (CRIC) project, Silent NEMO.

In a bid to find out the kind of struggles fish that live near hydroelectric power plants face, scientists have designed "sensor fish" — plastic tubes filled with technology that can measure the stresses and strains put on salmon swimming through dam machinery.

Autonomous, self-contained soft robotic fish at MIT

Soft robots — which don't just have soft exteriors but are also powered by fluid flowing through flexible channels — have become a sufficiently popular research topic that they now have their own journal, Soft Robotics. In the first issue of that journal, out this month, MIT researchers report the first self-contained autonomous soft robot, a "fish" that can execute an escape maneuver, convulsing its body to change direction, in just 100 milliseconds, or as quickly as a real fish can.

Noodlers Beware

CIA's Office of Advanced Technologies and Programs developed the Unmanned Underwater Vehicle (UUV) fish to study aquatic robot technology. The UUV fish named Charlie contains a pressure hull, ballast system, and communications system in the body and a propulsion system in the tail. It is controlled by a wireless line-of-sight radio handset.
