Actuation Characteristics of Basic Body Plans for Soft Modular Pneubotics in Architecture

The article examines the actuation characteristics of different basic structural schemes—basic body plans—for soft modular pneubotics in architecture are investigated. Eight basic body plans are translated from abstract expressions into their corresponding modular structures and (re)constructed in their physical form using up to 12 soft unit elements in the shape of a cube. Reconstructed basic body plans are then examined through a qualitative analysis of their ability to actuate and change the shape of the structure. Through adaptive manual inflation of an individual element, a group of elements, or all elements at once, motions and transformations are produced and evaluated. The results show that five out of eight basic body plans have higher actuation capacity while three show a less pronounced capacity to change shape. Based on the most pronounced characteristics of the examined basic body plans, design opportunities for potential architectural applications are proposed. These include structures that can self-erect, lift, tilt, bend, change thickness, curvature, etc. What is also shown is that basic body plans could be combined into one complex structural body.
