This research for the first time investigates the deployment dynamics of fluidic origami tubular structures, driven by internal pressurization using working liquid or air. Utilizing fluidics is attractive given that it is readily available in many engineering systems and is easy to realize and control, and embedding it in tubular origami is an effective innovation to create various advanced functionalities, which are not achievable in traditional origami even with adaptive materials. Despite fluidic origami’s potential as a promising inflatable deployable structure, the dynamics of its deployment have not been explored. This research advances the state of the art with intriguing new findings that have not been observed in previous studies and cannot be derived with traditional quasi-static analysis. In this investigation, the origami tube is constructed using the Miura origami pattern with the ends of the tube sealed and fluidic pressure …
