Abstract This work introduces a novel composite film actuator with dual actuation mechanisms, responsive to four distinct stimuli, and featuring infrared stealth as well amphibious locomotion capabilities. By encapsulating nanoscale VO 2 phase‐change materials PMMA coating them onto thin of micrometer‐scale Ti 3 C T x MXene, the achieves efficient photothermal conversion, high electrical conductivity, humidity‐responsive actuation. The is integrated into millirobots capable crawling, grasping, oscillating, achieving unrestricted movement on water surfaces. These demonstrate rapid response, stability, outstanding performance in both terrestrial aquatic environments, 90° angular change s, crawling speed 10 mm min −1 land, swimming 174 water. Additionally, this proposes mechanism based moisture absorption contraction properties further expanding application potential millirobots. advancements enable navigate confined spaces transport sensitive items without being detected by sensors. represents substantial leap forward soft robotics science, paving way for exploration advanced tailored complex applications.
