coffee lends me a hand… litterally

I have seen many research projects concerned with how to create a gripping technology like an arUniversal gripper 2tificial hand. It is extremely difficult to do so. Tendrons, sense of feeling and many other factors needs to be taken into account before you can handle something without destroying it.

Sometimes though… there is a much simpler soloution. At Cornell University two guys have created a gripper, that can grap most things that the human hand can grab.. and it is made from… coffee… that is coffee grounds, a balloon and a vaccum pump. Stock items in most households… well at least two out three should be.

I t works by having the coffee wrap itself around the item you wish to pick up, and then remove the air in the balloon. Thereby causing the coffee grounds to become a solid structure instead of a semi liquid material. It is so simple it is close to genious.

In a previous post I wrote about a sweedish guy who had a robot hand as a replacement for his real hand which was destroyed in an accident… maybe in a not so distant future we can have prostetic hands build on this principle… that would be very practical, cheap and faster to implement – albeit not quite as pleasing to the eye. Nothing is said regarding the color of the balloon though, so you could choose a color that goes well with your outfit…
