Smart shape-changing structures in aerospace applications are vulnerable to damage harsh environments. Balancing high mechanical performance with self-repair capabilities poses a challenge due inherent trade-offs between strength and flexibility. To address this challenge, an asymmetric bilayer-structured actuator was fabricated using commercially available continuous carbon fiber tows (CFs) as the passive layer dynamic cross-linked epoxy vitrimer active layer. The construction of vitrimer-CF involves simple scalable hot-pressing process, resulting tensile 234 MPa interfacial bonding 405 N·m–1. This exhibits remarkable deformation capability (210°/7 s) efficient ability under various stimuli, including thermal (60–160 °C), light (0.4–1.0 W·cm–2), electric (2–4 V), solvent (acetone). By adjustment orientation angle CFs, complex left-handed right-handed curling can be achieved. Leveraging insights from photothermal/electrothermal actuation mechanisms, quadruped crawling robot is developed capable 4 cm single illumination. lift objects 45 times its weight when subjected stimuli. Additionally, flap constructed achieve change 63° within 10 s stimulus, enabling remote control over aircraft flight angle. These results demonstrate potential for advanced intelligent structures.

Abstract Currently, numerous biomimetic robots inspired by natural biological systems have been developed. However, creating soft with versatile locomotion modes remains a significant challenge. Snakes, as invertebrate reptiles, exhibit diverse and powerful abilities, including prey constriction, sidewinding, accordion locomotion, winding climbing, making them focus of robotics research. In this study, we present snake-inspired robot an initial coiling structure, fabricated using MXene-cellulose nanofiber ink printed on pre-expanded polyethylene film through direct writing technology. The controllable fabrication structure (ICSBot) has achieved theoretical calculations finite element analysis to predict analyze the ICSBot, programmable ICSBot designed fabricated. This functions gripper capable grasping objects complex shapes under near infrared light stimulation. Additionally, it demonstrates multi-modal crawling in various environments, confined spaces, unstructured terrains, both inside outside tubes. These results offer novel strategy for designing fabricating coiling-structured highlight their potential applications smart multifunctional robotics.
