An unlisted video demonstration (from May 2010) of a robotic gripper. Unlike most robotic hands, which are modelled after a human/animal hand, this robot hand is made of a rubber bag that is filled with ground coffee.
The gripper is placed over objects, and deforms around them. The air in the bag is then sucked out, causing the coffee granules to pack tightly together.
The video shows the gripper pick up a wooden hemisphere, an LED, a spring, some plastic tubing, a playing jack, a tetrahedron, a foam ear plug, a small light bulb, a shock absorber, a raw egg (without breaking it), and then picks up a glass of water and pours it, and then picks up a pen and draws a square.
The hand was developed as a collaborative effort between University of Chicago, Cornell University, and US firm iRobot.
