You heard and saw correctly. Flight assembled architecture is a video showing small scale flying robotic agents assemble a wall over time by lifting bricks one by one and placing them in correct orientation due to pre programmed logic. It was part of an exhibit and installation covered by various outlets including but not limited to DeZeen, and Arch Daily. Imagine a swarm of robots attacking a site over a day and leaving a fully functional building behind much like an insect hive or birds nest. The project is an experiment by Swiss architects Gramazio & Kohler and Raffaello D’Andrea. Very exciting, they are using mouse traps to carry out their experiment.
