Harvard's robot arm traps delicate sea animals without harm
Researchers at Harvard's Wyss Institute have developed a robotic arm which uses an origami-inspired design that can trap delicate sea animals without risking any harm. Called RAD (Rotary Actuated Dodecahedron), it has petal-like fingers which form a ball shape around an animal in less than a second. The action is directed by the design and shape of the fingers.
