Abstract
We describe the design and implementation of a robotic interactive shape-changing display. Our shape-changing display is comprised of custom-built actuators and sensors made possible by advances in 3D printing technology, which makes our display substantially less costly and more scalable than other shape-changing displays. Specifically, the pixelated surface of our display is formed by the termini of a large number of linear actuators of our own design and fabrication, where each linear actuator is essentially a linear potentiometer. The robot display’s surface is made tangible by way of low-density foam embedded with electrically conductive polyurethane fibers. Presented in this paper are details of the design and implementation of our display, use cases (including gesture control of the surface and its capacity for transporting heavier loads), and a cost comparison with existing displays.
