The research group of the Institute for Dynamics Systems and Control, led by Raffaello D’Andrea at the ETH of Zurich, in collaboration with a team of architects led by Fabio Gramazio and Matthias Kohler, presented an installation in which a swarm of quadcopters autonomously pick up sequentially 1500 foam bricks (500 gr each) and position them at the right place to build a 6-meter tall tower with a sophisticated shape.
