Autonomous Flying Robotic Bees Build Tower in France
People sometimes raise their eyebrows at the claim that bricks are green, because of the energy needed to fire them. But they use a lot less energy than they used to, they last almost forever, they are recyclable, they have great thermal mass and are very low maintenance. Unfortunately the craft of bricklaying isn't what is was, and Eladio Dieste or Antonio Gaudi would have trouble finding trades today.
Fabio Gramazio and Matthias Kohler have been doing important work to change all that, developing robots that can lay bricks in ways that would impress Eladio. They even got their portable robot to build a wall in Manhattan two years ago. But robots weren't innovative enough for them; now, with Raffaello D’Andrea, they are building a twenty foot high tower with little robotic helicopter bees.
It is in fact a scale model of a much larger project, a 600 meter high "vertical village".
Just imagine, no more big trucks carrying building materials through the city, just millions of little busy bees carrying materials to the site and assembling a complicated building all by themselves. Just be sure to wear your hardhat when you go outside. More at Dezeen and Gizmag
