MIT researchers revive 40-year-old triangular zipper concept now made possible by 3D printing, creates shape-shifting robots and deployable structures — 3D-printed 'Y-Zipper' turns floppy tentacles into rigid beams in seconds
MIT researchers have revived a 40-year-old triangular zipper concept using 3D printing, creating shape-shifting robots and deployable structures. The "Y-Zipper" can turn floppy tentacles into rigid beams in seconds, offering potential applications in adaptive robots, fast-deploying shelters, and medical devices. The design, originating in 1985, was made possible by advancements in 3D printing technology and computational design tools. The system allows for customizable behavior, forming various structures like rods, arches, coils, or screw-like shapes. The researchers demonstrated the technology in a robotic quadruped with legs that can adjust height and stiffness, showcasing its potential in robotics and deployable systems.
