How to Build Rope Bridge using Quadrocopters / Flying Machine

Civil Engineering Tips

A rope bridge is a bridge constructed chiefly of rope. In its simplest form of bridge. It can be made of one or two ropes and is bridged over a river. A traveler is enable to cross the river by being supported by the bridge and does not get swept away with the flow. One rope above another, for feet and hands, may be referred to as a commando bridge.

In this video shared by Federico Augugliaro, shows how to build a rope bridge using the flying machines, quadrocoptersin the ETH Zurich Flying Machine Arena.

Aquadcopter, also called aquadrotor, is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors.

In this video, it can be seen that simple and structures can be built using the small flying machines. The rope used here is of Dyneema, a material having low weight-to-strength ratio and is suitable for aerial construction. The full erection of bridge is done with autonomous drones which are controlled by algorithms run on computers.

The drones are equipped such that it allows control on tension during the rope deployment while building. The external forces and torques exerted by the rope during deployment are accounted to achieve compliant flight behaviour.

The videos shows that small ?ying machines are capable of autonomously realizing load-bearing structures at full-scale and proceeding a step further towards real-world scenarios. Several computational tools are being developed to take this technology further, specifically addressing the characteristics of the building method. The design tools allow to simulate, sequence, and evaluate the structure before building.
