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.

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.
