From power plants on land to bridges over the sea, safety-critical built environments require periodic inspections for detecting issues avoid functional discontinuities of these installations. However, navigation paths in are usually challenging as they often contain difficult-to-access spaces (near-millimetre and submillimetre-high gaps) multiple domains (solid, liquid even aerial). In this paper, we address challenges by developing a class Thin Soft Robots (TS-Robot: thickness, 1.7 mm) that can access narrow perform cross-domain multimodal locomotion. We adopted dual-actuation sandwich structure with tuneable Poisson's ratio tensioning mechanism TS-Robots driven dielectric elastomers, providing them two types gaits (linear undulating), remarkable output force ( ~ 41 times their weight) speed (1.16 Body Length/s 13.06 Thickness/s).
