We investigate the extreme wave event in mechanical metamaterials composed of Triangulated Cylindrical Origami (TCO). Specifically, we focused on realizing rogue waves by employing a homogeneous one-dimensional chain constructed from the TCO unit cells. In association with data-driven methods, our numerical simulation suggests the wave focusing on a very limited number of unit cells, which can be potentially realized in the experimental setup. The mechanism of the wave localization using the TCO can be leveraged for efficient energy harvesting purposes in engineering applications.
