Abstract

Origami engineering is a promising approach to transforming structures and machines due to its potential for geometric, kinematic, and mechanical complexity. However, actuating this transformation can be expensive, slow, and unreliable. In this paper, we demonstrate repeatable and reversible transformation of a two-vertex origami string between different configurations using a stacked-Miura cell as an actuation system. We characterize the snap-through behavior of the cell and show how the cell can be coupled to the string to generate drive repeatable transformations between different configurations. We then show how gravity can affect this process. The results indicate that bistable origami cells are a promising method for lightweight, repeatable transformation.
