According to an article on New Scientist, a team comprising architects and roboticists at the Swiss Federal Institute of Technology is teaching UAVs how to build aerial webs.
Remarkably similar to how a spider would spin its web, the computer-controlled quadcopters spit out lines of plastic cable as they fly, interconnecting and weaving the material.
The vehicles are also being made to build structures from foam bricks. Ammar Mirjan, one of the architects, told New Scientist that a use for these vehicles “would be a structure like a bridge or a connection between existing buildings,” such as between two skyscrapers.
