Drones build rope bridge – video

Three quadcopter drones programmed by researchers self-assemble a bridge using ropes. The structure measures 7.4 metres long, consists of nine rope segments for a total rope length of about 120 metres and is able to hold an adult. It is hoped that the project, which took ETH Zurich three years to complete, will aide rescue efforts in natural disaster sites, reaching remote and inaccessible areas
