Between delivering packages and even successfully catching fish, it seems as though there is little that drones – or quadrocopters – can’t do these days. But what about building a bridge that can support two humans…autonomously?

In a new video YouTube video uploaded by programmer Federico Augugliaro, two drones use a high-precision motion capture system, a wireless communication network, and custom software executing sophisticated algorithms for estimation and control to build a rope footbridge without the aide of humans.

The experiment, which is just one of many performed by Augugliaro and a team of researchers at the Institute for Dynamic Systems and Control and Gramazio Kohler Research at ETH Zurich in Switzerland, is part of a larger body of research in aerial construction – field that “addresses the construction of structures with the aid of flying machines”:

“Spanning 7.4 m between two scaffolding structures, the bridge consists of nine rope segments for a total rope length of about 120 m and is composed of different elements, such as knots, links, and braids,” explains Augugliaro. “The rope used for these experiments is made out of Dyneema, a material with a low weight-to-strength ratio and thus suitable for aerial construction. Of little weight (7 g per meter), a 4 mm diameter rope can sustain 1300 kg.”

In order for the flying vehicles to feed the rope as they need it without getting tangled, they are each equipped with a spool that allows them to control the tension of the rope while deploying it.
