How to build a better future: high-tech Jenga at the Soane Museum
December 21, 2018 | Financial Times | Simon Ings.

Suspended from four wires, this digitally controlled cable robot is building something out of hand-size wooden blocks. It’s a slow beast. Hours must pass before its construction becomes recognisable: a dome, of the sort that John Soane produced for the Bank of England and Dulwich Picture Gallery.

Polibot does not look like a game changer. But according to Arthur Mamou-Mani, whose architectural practice built it, Polibot’s children are going to change the world.......in the early 2000s, computer-generated design was a fairly dry topic. Patrik Schumacher, principal of Zaha Hadid Architects, dubbed it “parametricism”, reflecting the way programmes evolve forms according to a set of parameters........Through experiments in robotics, Mamou-Mani’s practice is out to develop new ways of building that will make architecture, engineering and construction merge into single field. The point is not what Polibot is, but what it could become. It’s not just a pick-and-place machine. It’s the early prototype of a universal builder.....There have been many experiments in the large-scale 3D printing of buildings. But the kinds of industrial robot arms that are usually employed for this work are far too cumbersome and delicate to wheel on to a building site....Gigantic robot arms will never spew out skyscrapers at a single sweep, Mamou-Mani says, for the simple reason that it would make construction less, not more efficient....construction is mostly about bringing big chunks of stuff together,” he says. “Currently, concrete is still the material of choice for the construction industry, but we’re slowly switching to timber, and this will be a massive revolution, because once you start working with timber, you’re no longer casting anything on site. You’re thinking entirely in terms of prefabrication and assembly.”Mamou-Mani dreams of building simple towers from elements (“prefabricated properly, by robotic arms, like cars”) assembled on site by gigantic Polibots....Mamou-Mani explains his vision of buildings that can expand and contract, depending on the economy....Why do we think that permanence is necessary?” Elsewhere in the show, the wall text proclaims that “the best cities are the ones that don’t leave ruins”....All great advances in industrial culture are prefigured by model-making.
