LOG KNOT: Robotically Fabricated Roundwood Timber Structure

Abstract

LOG KNOT is a robotically fabricated architectural installation which aims to expand and optimize the use of entire trees and irregular timber geometries in construction. LOG KNOT creates an infinite loop of roundwood, curving three-dimensionally along its length. The project borrows strategies from tradi¬tional wood building and manufacturing, while implementing contemporary technologies to achieve precision and mass customization. By utilizing robotic fabrication processes and 3D scanning, it is possible to create complex timber curvature that requires minimal formwork for assembly, thus reducing waste and optimizing the use of valuable timber resources. LOG KNOT’s design is based on naturally existing timber geometries found in mature ash trees infested by the Emerald Ash Borer. Furthermore, the installation capitalizes on the idiosyncrasies of such irregular roundwood components. In a reciprocal design process, the project fosters synergies and feedback between material, fabrication, digital form, and full-scale construction.
