Description

<p>We developed a compliant underactuated mechanism composed of a skeleton layer with diagonal pre-folding lines functioning as joints and a sliding layer made of polymer sheet. This configuration allows the sheet to softly coils around an object in a three-dimensional helical shape. Inspired by the origami, this mechanism is designed from a single polymer sheet. In this paper, we describe the motion principle and geometric model of the proposed mechanism, followed by its implementation and preliminaly evaluation.</p>
