Abstract Self‐oscillation phenomena observed in nature serve as extraordinary inspiration for designing synthetic autonomous moving systems. Converting self‐oscillation into designable self‐sustained locomotion can lead to a new generation of soft robots that require minimal/no external control. However, such is typically constrained single mode dictated by the constant surrounding environment. In this study, liquid crystal elastomer (LCE) robot capable achieving multimodal locomotion, with specific motion being controlled via substrate adhesion or remote light stimulation presented. Specifically, LCE mechanically trained undergo repeated snapping actions ensure its rolling gradient thermal field atop hotplate. By further fine‐tuning adhesion, exhibits reversible transitions between and jumping modes. addition, be manipulated real time through perform other diverse motions including turning, decelerating, stopping, backing up, steering around complex obstacles.
