During the 20th annual Barcelona Building Construmat last May, the Institute for Advanced Architecture of Catalonia (IAAC) demonstrated its On Site Robotics project to show how 3D printing, drones and robotics mesh together in construction.
The On Site Robotics project uses cable-driven robots, similar to those used to record football games, to do the 3D printing. The drones are fitted with cameras that monitor the construction site to measure how quickly the printed structures are drying.
It's an elegant process. Watch it here:
