Excerpt from intersystem comm logs, 2025
Eric Brown and co-workers at the University of Chicago have just published their design for an entirely non-anthropomorphic robot gripper based on the “jamming” principle. The gripper consists of a spheroid balloon, filled with dry coffee grounds, which can be filled with air or evacuated through the arm. Adding air expands the balloon and lets the coffee grounds flow freely around an object; withdrawing it contracts the balloons and “jams” the grounds in place around that object.
