Here at Hackaday, we love it when people make home brew versions of elaborate, expensive, and technical equipment. By gathering up some coffee grounds, a balloon, some plastic tubing, and his lungs, [Carlos] has provided a good how-to on making your own coffee grounds robotic hand. Inspired by the U. Chicago, Cornell, and iRobot Collaboration we previously covered, he is one robot and a vacuum pump away from having their setup. Check out his blog for a list of components as well as a couple hints to help the build go smoothly. Be sure to check out the video after the break.

Picking up a raw egg is not something we’d think a robot gripper would be good at. But this model uses a bulbous tip instead of claw, which makes crushing the object less of a concern.
That tip is kind of like a balloon. It is stretched full with coffee grounds but air can also be pumped in and sucked out. When it comes time to grip an object, a bit of air is pumped in and the bulb is pressed down on its target. Once in place all of the air is sucked out, locking the coffee grounds around the object. Take a look after the break to see just how many things can be gripped with this technique.
Now the real question, can it bring me a beer?
