Ori-Pixel, a Multi-DoFs Origami Pixel for Modular Reconfigurable Surfaces

摘要: Reconfigurable surfaces using robotic pixels can produce discretize 3D contours, shapes and motion patterns. In existing devices, the rendering resolution richness of patterns are limited by use linear that only single DoF (only change their extrusion/ height). Challenges in designing compact yet modular mechanisms scaling manufacturing have development more complex but versatile multi-DoFs pixels. Utilizing an origami approach, we designed, prototyped controlled Ori-Pixel , a 3-DoFs parallel robot control its height, pitch roll angles. These additional DoFs allow greater variety primitives, replicating curved contours accurately, manipulating objects smaller than actual pixel size. The folding joint design, multi-layer discussed letter. workspace, stiffness, power consumption communication rate Ori-pixel experimentally characterized confirmed with prototype platform. We also report Ori-Pixels applications two case studies: (i) interactive flag consisting 5 × 5 matrix reacts to users’ gestures; (ii) set 33 morph surface concept car.
