Enter the new fish-shaped "soft robot" developed by Andrew Marchese, a graduate student in MIT's Department of Electrical Engineering and Computer Science. It can execute an escape maneuver called a "C-turn" in about 100 milliseconds, matching the speed of fish in the wild. Such swiftness is one of the things that most sets this robofish apart.
Soft robots are machines that have gushy exteriors and move around through the use of fluids or gases pumping … Read more
