Watch two drones build a rope bridge

Strong enough to walk across

Engineers at the Swiss Federal Institute of Technology in Zurich have developed a pair of quadcopters that can collaboratively assemble a rope bridge that's sturdy enough for a person to walk across.

The drones used Dyneema rope - a material with a notably low weight-to-strength ratio - to connect two scaffolds about seven metres apart in ETH Zurich's Flying Machine Arena. The robots use several rope techniques - including knots, links and braids - to make the bridge possible. Here are the drones in action:

Real World Scenarios

What's harder to see in the video above is that the whole room is equipped with a motion capture system that tells the drones their position relative to the scaffolds and each other. That data is processed through a computer that then sends commands out to the flying drones.

The researchers behind the feat said in an online description of the project: "The rope bridge acts as a demonstrator, showing for the first time that small flying machines are capable of autonomously realizing load-bearing structures at full-scale and proceeding a step further towards real-world scenarios."
