PneuSeries: 3D Shape Forming with Modularized Serial-Connected Inflatables
summary
A serial inflatable system that forms 3D shapes using modular cubical, cuboidal, tetrahedral, prismatic and custom units connected with embedded bidirectional check valves and fast screw connectors, allowing one pump controls all modules through stage‑by‑stage inflation/deflation. Prototypes use cardboard-reinforced folding skins; experiments measure flow rates and cracking pressures and show cracking pressure tuning speeds late-stage inflation. A simulator predicts timing and the results simulation matches experiment. Examples: 3D arrays with overhangs, a programmable-tilt holder, a collapsible shelf, and a sword-to-ball transform.
