| summary |
The architecture and construction industries have been developing methods to integrate Augmented Reality (AR) and Mixed Reality (MR) workflows into the building industry for 1-to-1 scale design, visualization, and paperless fabrication. While these AR workflows have been primarily focused on mono-material assemblies, this paper investigates the potential of AR and MR for multi-material fabrication, combining various materials and structural components throughout each phase of the construction of the Unlog Tower. The installation uses infested and dying ash trees to construct a 36-foot-tall triangular, lightweight timber structure. The Unlog Tower leverages bending active elastic kinematics to stretch robotically kerfed logs braced by threaded rods and tube steel. Three extended reality (XR) workflows were explored for the construction of this bespoke timber struc- ture: (1) fiducial marker coordinated AR instruction, (2) multiple QR code AR instruction, and (3) gesture-based MR instruction. These XR workflows incorporate feedback-based construction notation and animation for the assembly of non-standard natural materials and standardized parts through three construction phases: materials to parts, parts to prefab modules, and onsite assembly. The research highlights the potential of AR and MR workflows for human-machine interaction in robotic fabrication, analog means of making, prefabrication, onsite construction, and coordination. The result of this investigation has demonstrated many advantages and disadvantages of varying AR/MR workflows in facili- tating the construction of multi-material and multi-phase structural assemblies. |
