Abstract: In a method of manufacturing a highly stretchable three-dimensional (3D) percolated conductive nano-network structure, a 3D nano-structured porous elastomer including patterns distributed in a periodic network is formed. A surface of the 3D nano-structured porous elastomer is changed to a hydrophilic state. A polymeric material is conformally adhered on the surface of the 3D nano-structured porous elastomer. The surface of the 3D nano-structured porous elastomer is wet by infiltrating a conductive solution in which a conductive material is dispersed. A 3D percolated conductive nano-network coupled with the 3D nano-structured porous elastomer is formed by evaporating a solvent of the conductive solution and removing the polymeric material.

Abstract: A mobile robot control apparatus includes an online 3D modeler and a path planner. The online 3D modeler is configured to receive an image sequence from a mobile robot and to generate a first map and a second map different from the first map based on the image sequence. The path planner is configured to generate a global path based on the first map, to extract a target surface based on the second map and to generate a local inspection path having a movement unit smaller than a movement unit of the global path based on the global path and the target surface.

Abstract: A method for the large-scale synthesis of a zeolite-templated carbon (ZTC). The method includes the steps of: introducing a bed material comprising a zeolite to a fluidized bed reactor and heating the bed material to a temperature between 550° C. and 800° C.; fluidizing the bed material with a fluidizing gas and maintaining the temperature of the bed material between 550° C. and 800° C.; introducing an organic carbon precursor while fluidizing the zeolite for a period of time such that carbon is deposited on the zeolite by chemical vapor deposition to produce a zeolite-carbon composite; and treating the zeolite-carbon composite with an acid solution such that the zeolite template is dissolved and the ZTC is obtained.
