Опубликована: Май 27, 2022

Wireless soft-bodied robots at the millimeter scale allow traversing very confined unstructured terrains with minimal invasion and safely interacting surrounding environment. However, existing untethered soft millirobots still lack ability of climbing, reversible controlled surface adhesion, long-term retention on three-dimensional (3D) surfaces, limiting their use in biomedical environmental applications. Here, we report a fundamental peeling-and-loading mechanism to climb 3D surfaces by using both soft-body deformation whole-body motion robot under external magnetic fields.
