Cables are critical in engineering structures for load‐bearing, electronic connection, and mechanical transmission. Various cable‐crawling robots (CCRs) have been developed to perform scheduled inspection or convey supplies. Most existing CCRs often actuated by motors used large‐scaled structures. The heavy bodies of these can cause damage even casualties once slippage drop occurs. A small lightweight CCR that crawl on thin cables is highly demanded safety narrow confined inner spaces...
Structural coloration in biomimetic nanostructures has remarkable application potential vivid display devices, but their color change effect is still insufficiently competitive towards biology. Inspired by the feather of a hummingbird, new methodology for proposed. A structure-colorable flexural artificial muscle (FlexAM) developed integrating view-angle dependent photonic diffraction grating pattern and voltage-actuated dielectric elastomers as an electroactive entity via laminated object...
Cable-Crawling Robots In article number 2300828, Bo Li, Guimin Chen, and co-workers report a centimeter-scaled cable-crawling robot for thin cables by utilizing multilayered dielectric elastomer actuators. The miniaturized (2.1 g, 43 mm long) can quickly crawl on extremely with different orientations, transport objects, locomote across the water–air interface. Benefit from excellent locomotion performance, be applied to perform inspection maintenance tasks along pre-built inside some...
Cephalopod skin is capable of fast color changing enabled by tunable transparency as well structure color. Under this inspiration, herein, a flexible surface with unique hierarchical that integrates both change in chemical (optical scattering) and coloration interfering) developed harnessing wrinkling instability, thanks to the interfacial Au catalysis soft lithography. As result, terms wrinkled film overlaid nano‐dome array obtained flexile surface. Experiments find subject biaxial strains...
A soft bistable actuator can generate high-speed motion between two prescribed stable positions, which is very useful for boosting the actuation of robots. Generally, stroke such an completely determined once design finalized, prohibits its applications in robots that perform multiple tasks. In current work, a with adjustable characteristics proposed by exploring strain energy landscape, barrier manipulatable via electroactive twisted and coiled polymer fibers. As such, operate either or...
Coexisting micro-/nanostructures on a stretchable substrate offer localized functionality with programmability and dynamic regulation. Yet, the combination of different fabrication techniques is challenging. In this paper, one-step methodology for such surface proposed by harnessing wrinkle instability at targeted area selected mechanical constraint during soft lithography. Partly covered patterned constraints, nanostructures that replicate template obtained while unconstraint part wrinkles...
