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 into 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. The article includes a video of the hand in action."
The most difficult thing in the world is to know how to do a thing and to
watch someone else doing it wrong, without commenting.
