Building a rope bridge with flying machines
Watch quadrocopters weave a rope bridge strong enough to walk on. Made at the ETH Zurich Flying Machine Arena in Switzerland, the bridge joins two scaffolds, and is the first full-scale load-bearing structure autonomously built by flying machines. Except for the metal scaffolding at both ends of the structure, the bridge consists exclusively of Dyneema rope, a tensile material with low weight-to-strength ratio which makes it ideal for aerial construction. The project was developed at a research and demonstration platform for aerial robotics. The arena is equipped with a motion capture system that provides vehicle position and attitude measurements for the small custom quadrocopters. An offboard computer runs the algorithms and sends commands out to the drones via a customized wireless infrastructure.
