It was quite obvious from theory of gripping that geometric solutions using hand and finger anthropomorphy were one approach, just getting the grip done a different one.<\/p>\n

Now here is a universal robot vacuum gripper, very cool and versatile:<\/p>\n

When this hand comes in contact with an object, a small pipe sucks air from the sack, causing it to contract and mold to the object’s shape. The contraction is small\u0097a mere 1% change in volume\u0096but was enough to grab most objects the researchers tested. “It’s very simple to control,” notes Brown. “You don’t have all these joints.”<\/em><\/p>\n

DIY universal robot gripper<\/strong><\/p>\n

Our friend Carlos made the Flexible Robot Gripper shown above. It\u0092s based on the one made by a team at Cornell University, the University of Chicago and iRobot demonstrated in the video below. I wonder if this is the future of robot grippers? I worked in a company where the robot we were working with had the typical grippers and when programming them there was no room for error since a mm of error meant that the object was dropped. You can see the materials that Carlos used below, I am thinking that most of the build cost is tied up in the balloon.<\/p>\n
