Swiss architects Gramazio & Kohler and Raffaello D’Andrea are a fully automated construction project at the FRAC Centre in Orléans, France that uses flying robots to assemble a six meter high tower constructed of 1500 polystyrene foam bricks. The exhibit lasts from up to February 19, 2012. The same team previously used a robot called "R-O-B" to build a looping wall in New York and the award-winning Structural Oscillations installation at the 2008 Venice Architecture Biennale.
