Multibody kinematic dimensional synthesis of a novel passive ankle exoskeleton with biomimetic kinematic response containment

Abstract To address uncertainty-induced kinematic response fluctuations in passive ankle exoskeletons, a bioinspired passive compliant ankle-exoskeleton structural concept is proposed. The design integrates four biomechanical subsystems: (I) a soleus muscle-inspired elastic-dampi...

3D cuboid: Research on spatial geometric similarity scaling in conformal mapping

Abstract: This paper investigates the problem of self‑similar fractal proportions in three‑dimensional space and derives the unique aspect ratio (approximately 1.5874:1.2599:1) for a cuboid that satisfies the property of "shape invariance after bisecting the longest edge." Cuboid...
