Coffee Ground Filled Balloon Gripper Holds Promise

The age-old problem of creating a robotic gripper capable of grasping unusually shaped objects has advanced one more step with this interesting development from researchers at Cornell, the University of Chicago and iRobot Corp. The Universal Gripper as they call it consists of a balloon filled with a jam-able particulate. When the balloon comes in contact with an object it conforms easily, then when a vacuum is applied, the particulates interlock providing the grasping action. Early material included rice and ground-up tires, but coffee seems to work really well. Video
