Submission + - Robotic hands grip without fingers (sciencemag.org)

sciencehabit writes: Physicists have designed a robotic hand that doesn't have fingers, yet can still serve drinks and draw pictures. The hand is a thin rubber sack filled with coffee grains or small glass spheres. When it comes in contact with an object, a small pipe sucks air from the sack, causing it to contract and mold to the object's shape. As long as the gripper can fold about one-fourth of the object's surface, it can pick up just about any shape thrown in its path. (video included)
