Abstract

Tunable, soft, and multifunctional robots are contributing to developments in medical and rehabilitative robotics, human-machine interaction, and intelligent home technology. A key aspect of soft robot fabrication is the ability to use flexible and efficient schemes to enable the seamless and simultaneous integration of configurable structures. Here, we report a strategy for programming design features and functions in elastomeric surfaces. We selectively modified these elastomeric surfaces via laser scanning and then penetrated them with an active particle–infused solvent to enable controllable deformation, folding, and functionality integration. The functionality of the elastomers can be erased by a solvent retreatment and reprocessed by repeating the active particle infusion process. We established a platform technique for fabricating programmable and reprocessable elastomeric sheets by varying detailed morphology patterns and active particles. We used this technique to produce functional soft ferromagnetic origami robots with seamlessly integrated structures and various active functions, such as robots that mimic flowers with petals bent at different angles and with different curvatures, low-friction swimming robots, multimode locomotion carriers with gradient-stiffness claws for protecting and delivering objects, and frog-like robots with adaptive switchable coloration that responds to external thermal and optical stimuli.
