WALLS BUILT BY AN ARMY OF FLYING ROBOTS!

I am lost for words! this is possibly the best way to build walls, I think that this should be the way all walls are built in the future, it takes away the mess of inaccuracy out of wet trades. An army of flying robots place hundreds of blocks perfectly to build a complex undulating structure that was built over a few days. The flying robots were engineered by ETH Zurich, the project was conceived and designed by architects Fabio Gramazio and Matthias Kohler of Gramazio & Kohler. The installation was named Flight Assembled Architecture.
