We were pretty impressed by the potential of these flying robots when we first covered this story in late November. Now the FRAC Centre in Orléans, France has released a video of the robot swarm in action during its current exhibition. Titled "Flight Assembled Architecture," the live installation showcases a fleet of quadrocopters building a six meter-high tower made up of 1,500 prefabricated polystyrene foam modules.

Each quadrocopter is fitted with custom electronics and onboard sensors to allow for precision vehicle control, whilst also providing the opportunity for pre-programmed flight paths, which could include arcs and spirals. Furthermore, the fleet management technology helps avoid collisions by taking over when the flying robots get too close to each other. The same technology is also used for automating routine take-offs, landings and vehicle calibration and charging.

The exhibition was developed by Swiss architect Gramazio & Kohler and Italian robot designer Raffaello D'Andrea.
