Fold‐Cut Structures with Tunable Stiffness for Multimorphing Soft Robots

Versatile changes in shape and mechanical properties can take the adaptability and functionality of soft machines to the next level for operating in complex, inaccessible environments. Soft machines designed with origami or kirigami, the ancient paper art of folding or cutting, have been shown to perform remarkably in severe geometric conditions or situations through shape morphing. However, conventional origami‐ or kirigami‐inspired machines rely on a single, monotonous morphing pathway, thereby limiting their achievable functions. Recent designs integrate both origami and kirigami to enable multimorphing; however, they frequently require numerous actuators or inputs, increasing system complexity. Here, a highly deformable “ori‐kirigami” robotic structure is presented by operating both folds and cuts on a 2D tessellated sheet, possessing multiple morphing pathways and tunable mechanical…
