Researchers have developed a new type of robot griping system, which is able to handle objects of any shape, by utilizing a complete different system than usual robot grippers. The system is based on a totally new concept of filling a flexible container, such as a party balloon, with granular material and removing the air in the balloon after the object is contacted. The researchers surprisingly found that regular coffee grains have suitable properties for this task. Removal of the air in the balloon causes coffee grains to solidify around the contacted object, which ensures a strong grip. This type of grippers might find many practical applications, the researchers say. For original story, and to watch a video of the gripper, please visit here.
