New 3D-printing method lets soft robots bend and grasp on command

Harvard engineers embed motion directly into soft robots with a rotational multimaterial 3D‑printing process that creates hollow pneumatic channels inside flexible filaments. When inflated, these channels cause the structures to bend, twist, or grasp in preprogrammed ways, removing molds and assembly steps and enabling rapid design changes. Demonstrations include a flower-like actuator and a hand-shaped gripper, with potential applications in surgical robotics and delicate-object handling.
