Inspired by nature, where organisms adapt their shapes to navigate complex challenges, engineering systems can benefit from reconfigurable designs that move beyond rigid, conventional strategies. Reconfiguration offers a promising solution for systems to adapt dynamically to changing operational requirements. Origami, known for its ability to transform from simple 2D sheets into intricate 3D structures, provides a powerful framework for designing adaptable and reconfigurable systems. In this study, a waterbomb origami-based (WOB) crawler is proposed featuring reverse movement without changing actuation. The unfolding and folding process of the WOB enables motion due to the friction between the vertex and the ground, whereas the reverse movement is achieved by leveraging the local bistability of one WOB crease.
