Abstract: In this paper, a mobile robot with transformable wheel-legged mechanism is proposed to effectively cope with unstructured terrain in the work environment, especially steps. By using the combination of ratchet-crank-pilot ...

Abstract: Spacecraft are subjected to various dynamic loads due to shock from stage and fairing separations, resonant burn of the rocket motor, pressure oscillation in liquid engines, wind and gust, etc. These dynamic loads are very ...

Abstract: The existing regular hexagonal cellular substrate for stretchable electronics minimizes the disruptions to the natural diffusive or convective flow of bio-fluids. Its anisotropy is insignificant, which is not ideal for ...

Abstract: Vibrational microplatforms that exploit complex three-dimensional (3D) architectures assembled via the controlled compressive buckling technique represent promising candidates in 3D micro-electromechanical systems (MEMS), ...
