Video | Drones build rope bridge

Swiss students studying aerial construction have used drones to build a rope bridge that can carry the weight of a person.

They released a video that shows that the small quadrocopters can build load-bearing structures. Except for the anchor points at each end of the bridge, the connections were all completed by the drones.

The bridge spans 7.4m between two scaffolding structures and consists of nine rope segments. Around 120m of rope was used and the bridge includes knots, links, and braids. The drones had a motorized spool that allowed them to control the role tension and plastic tubes are used to guide the role.

The work was a collaboration between the Institute for Dynamic Systems and Control and Gramazio Kohler Research at ETH Zurich.

    Shades of the Americans designing a no gravity ball point pen for their space programme while the Russians took pencils. You can cast a weighted throwing line 8 metres with ease.
