Coffee-filled roboTIc gripper becomes a commercial product
The Versaball grasps a shock absorber

Back in 2010, we first heard about a clever device known as the roboTIc universal jamming gripper. With its business end composed of a party balloon filled with coffee grounds, it could form a secure grip around objects of varying sizes and shapes. Device has been commercialized – although incorporaTIng higher-tech materials than balloons and coffee.
Created in a collaboraTIon between the University of Chicago and Cornell University, the new version of the gripper is called the Versaball, and it's being produced by spin-off company Empire Robotics.
It utilizes the "jamming transition" phenomenon, in which granular objects remain loose and almost liquid ordinarily, but jam together to form a solid when vacuum-packed. It's the same process by which a package of vacuum-packed coffee feels rock-hard when Sealed, but becomes soft and pliable once opened.
In the case of the Versaball, a granular material is packed into a rubber ball on the head of the device. That ball has a bean bag-like consistency when initially pressed onto an object, letting it conform to the shape of that item. A Vacuum is then applied inside the ball, drawing out the air and causing it to "harden" around the object. The Versaball can then pick the item up (as long as it weighs no more than 20 lb/9 kg), move it, Then release it simply by releasing the vacuum.
Although the first version will be aimed at industrial applications, it is hoped that subsequent models could find use in assisted living devices, prostheses, and military robots.
The team that designed the initial prototype apparently had had plans to commercialize the technology, but changed their minds after receiving inquiries from a number of companies. Empire is now taking orders for the device, which should begin shipping later this month. It can be seen In action in the video below.

Back in 2010, we first heard about a smart device called the universal jamming clip for robots. Its commercial terminal consists of a party ball filled with coffee grounds that creates a safe grip around objects of different sizes and shapes. The device is now commercialized, although it contains higher technical materials than balloons and coffee.
Founded between the University of Chicago and Cornell University, it is known as the collaboration between the new version of the Versaball gripper, and it is being produced. Detach the company's Imperial Robot.
It takes advantage of the "interference transition" phenomenon in which the granular objects remain loose and almost liquid normally, but when the jams together form a solid, they are vacuum packed. This is the same process in which a pack of vacuum-packed coffee feels hard when it is sealed, but becomes soft and pliable once it is opened.
In the case of Versaball, the particulate material is loaded into a rubber ball to the head of the device. The ball has a bean-like consistency when initially pressed onto an object to conform to the shape of the item. The vacuum is then applied by the ball, drawing air out and "hardening" around the object. Then, Versaball can choose the item (as long as it weighs no more than 20 pounds)
9 kg), move it, then release the vacuum to release it at all.
Although the first version will target industrial applications, it hopes that subsequent models will find life aids, prosthetics, and military robots.
The team that designed the initial prototype apparently did not plan to commercialize the technology, but the companies that were surveyed changed their minds. The Empire is now accepting orders for equipment, and it should start shipping later this month. It can be seen in the action in the video below
