ONLINE COVER Robot on the Wall. Terrestrial robots that can operate on horizontal and vertical surfaces will enable more opportunities for their application in the real world. Hong et al. have developed a fast-climbing legged robot that can scale ferromagnetic walls and ceilings, maneuver over small obstacles, and carry payloads. The quadruped robot called MARVEL (Magnetically Adhesive Robot for Versatile and Expeditious Locomotion) climbs using specially designed feet based on electro-permanent magnets and magnetorheological elastomers. This month's cover is a photograph of MARVEL climbing on a ferromagnetic surface.

A DNA framework nanomachine enables single-vesicle quantification of resting pH values during vesicle fusion.

Abstract

Biomimetic machines that can convert mechanical actuation to adaptive coloration in a manner analogous to cephalopods have found widespread applications at various length scales. At the nanoscale, a transmutable nanomachine with adaptive colors that can ...

A foot design with electro-permanent magnets and magnetorheological elastomers enables dynamic legged climbing.

Abstract

A climbing robot that can rapidly move on diverse surfaces such as floors, walls, and ceilings will have an enlarged operational workspace compared with other terrestrial robots. However, the climbing skill of robots in such environments has been limited ...

The geometry of multisegmented thermo-responsive gel robots was manipulated to break symmetry and support locomotion.

Abstract

Reversible thermoresponsive hydrogels, which swell and shrink (deswell) in the temperature range of 30° to 60°C, provide an attractive material class for operating untethered soft robots in human physiological and ambient conditions. Crawling has been ...
