Abstract Magnetic soft robots with multimodal locomotion have demonstrated significant potential for target manipulation tasks in hard‐to‐reach spaces recent years. Achieving universal between and their targets requires a nondestructive easily switchable interaction broad applicability across diverse targets. However, establishing versatile dynamic interactions robotic systems remains challenge. Herein, series of magnetic millirobots capable magnetically adhesion is reported. Through two‐photon lithography‐assisted molding, double‐reentrant micropillar arrays liquid repellency are fabricated on the robots. These can serve as units to effectively manipulate various geometries (0D, 1D, 2D, 3D) both air water. As proof‐of‐concept demonstrations, these adhesive perform complex tasks, including circuit repair, mini‐turbine assembly, high‐speed underwater rotation turbine machine. This work may offer approach non‐magnetic objects through amphibious adhesion, emerging new paradigm manipulation.
