Digital Twin in Computational Design and Robotic Construction of Wooden Architecture

Abstract

This study proposes a cyber-physical interconnection method for computational design and robotic construction in a wooden architectural realm. It aims to provide a highly efficient, flexible, and adaptive design-construction approach by continuously updating digital models and physical operations according to the locally sourced materials. A perception-modeling system to scan the source materials on-site and send their data simultaneously to design software was developed by using physical sensors and computational technologies in an innovative manner. The data was used for architectural programs to generate design outcomes and guide the robotic construction. The novelty of this study is to establish a real-time, bidirectional interaction mechanism between digital design and physical construction. The design outcome is no longer a fixed, predefined geometric model but a dynamic, data-driven model which would be updated by material conditions on-site. The construction robot is able to make synchronous adjustment automatically in coordination with the dynamic design. The success of the iterative perceiving-simulating-updating loop was demonstrated by building two pavilions.

Artificial Intelligence Driven Promotion of Cultural Heritage Protection in the Context of Harmony Rural Construction

“…Firstly, in the form of questionnaire, a survey questionnaire was distributed to 80 root carving craftsmen, root carving market merchants and root carving collectors, with a recovery rate of 100% and an effective rate of 100%. Because of the innovative application of resin materials in this paper, the acceptance of traditional root carving art practitioners is highly uncertain, so it is evaluated and the acceptance table of resin/nylon and other 3D printing materials by root carving industry practitioners is obtained [19]. Synthesize the contents of other investigations related to this root carving product, sort out and analyze the data, and get the basic identification degree, artistic evaluation, commodity evaluation and other data of this product as shown in Table 1.…”

Digital Twins for Construction Assets Using BIM Standard Specifications

“…Almost all of these studies were based on on-site case studies, except for [174][175][176], which fully or partially focused on the off-site production of modular pre-fabricated building components. The studies in this field were divided into the following groups: robotics in construction [177][178][179][180], safety management [52,[181][182][183][184][185][186][187][188][189][190][191][192][193][194][195][196], and project performance monitoring [45,126,[174][175][176]180,189,[197][198][199][200][201][202][203][204][205][206][207][208][209][210][211][212][213]…”

Implementation of a Robotic System for Overhead Drilling Operations: A Case Study of the Jaibot in the UAE

“…To solve this problem, updating the robot with real-time information of the construction site is necessary; thus, we can rely on digital twin construction (DTC) such as real-time updated BIM models. For example, Ye et al [18] established a real-time interaction mechanism between digital design and physical construction. The design outcome is a dynamic, data-driven model, which would be updated by material conditions on-site.…”
