Robotic hands made quickly and easily out of plastic have loads of benefits over the traditional metal hands.

Aaron Dollar, an assistant professor of mechanical engineering at Yale, has invented a robot with a soft touch. His plastic hand is deft enough to grasp a wide variety of objects without damaging them. What’s more, it’s cheaper and requires less processing power than the metal hands typically used in robots.

Dollar’s design uses plastic fingers that can lightly brush against an object–whether it’s a wine glass, beach ball, or telephone–before firming up their grip…
