Ephemeral Myographic Motion: Repurposing the Myo Armband to Control Disposable Pneumatic Sculptures

Abstract: This paper details the development of an interactive sculpture built from deprecated hardware technology and intentionally decomposable, transient materials. We detail a case study of "Strain" - an emotive prototype that reclaims two orphaned digital artifacts to power a kinetic sculpture made of common disposable objects. We use the Myo, an abandoned myoelectric armband, in concert with the Programmable Air, a soft-robotics prototyping project, to manipulate a pneumatic bladder array constructed from condoms, bamboo skewers, and a small library of 3D printed PLA plastic connectors designed to work with these generic parts. The resulting sculpture achieves surprisingly organic actuation. The goal of this project is to produce several reusable components: software to resuscitate the Myo Armband, homeostasis software for the Programmable Air or equivalent pneumatic projects, and a library of easily-printed parts that will work with generic bamboo disposables for sculptural prototyping. This project works to develop usable, repeatable engineering by applying it to a slightly whimsical object that promotes a strong emotional response in its audience. Through this, we transform the disposable into the sustainable. In this paper, we reflect on project-based insights into rescuing and revitalizing abandoned consumer electronics for future works.
