Flying Robots Build Structure
Videos for Engineers

Flying Robots Build Structure - RF Cafe Video for EngineersIs this the future of construction? In this video, wirelessly controlled flying robots carry building blocks to the work site and, after precisely positioning the block, plunks it into place. It then flies off to pick up and place the next block. Multiple builder bots are in operation simultaneously. A 20-foot tall model (1:100) of a modularized human habitat structure - a "vertical village" - was constructed automatically using 1,500 polystyrene blocks. A sophisticated algorithm defined not just the construction sequence and geometry, but also handled traffic patterns, collision avoidance with other vehicles and the structure itself, and maximized system efficiency. ETH Zurich roboticist Rafaello D'Andrea and architects Fabio Gramazio and Matthias Kohler are the progenitors and implementers of this amazing demonstration. BTW, the hissing sound in the background is a painter spraying the blocks white.
