Flying robots build tower

Four small quadcopters are building a six-meter-high tower from concrete foam blocks. It is worth noting the independent navigation, high accuracy and strict compliance with the work of a given plan.

This project is the fruit of the collaboration of Raffaello D'Andrea, a robotics specialist from Zurich Swiss High School of Engineering, and architects Fabio Gramazio and Matthias Kohler. Previously, they taught flying robots to juggle a ping-pong ball .
