Augmented Reality Assistance in Assembly Tasks – DigitalTWIN

Short Introduction

DigitalTWIN is a completed research project focused on developing digital tools and technologies for the construction industry’s entire value chain. Funded by the German Federal Ministry for Economic Affairs and Climate Action, the project aims to bring small and medium-sized construction companies into the digital age. By integrating technologies like 3D printing, augmented reality, and cloud-based data analysis, DigitalTWIN enables more efficient and automated construction processes, streamlining coordination and decision-making from planning through to building operation. This approach simplifies coordination and decision-making across all project stages, from planning to operation, helping companies optimize building lifecycles and stay competitive in an increasingly digitized global market.

Description

The demonstrator showcases an efficient and streamlined assembly process using advanced digital tools, particularly in complex construction environments. Augmented Reality (AR) glasses provide workers with real-time instructions and essential data, replacing traditional paper-based manuals. The demonstration focuses on assembling a lattice shell structure, where workers follow step-by-step sequences, identify and locate components, and document key tasks like verifying part positions or tightening bolts to the correct torque. Remote access enables engineers to conduct live inspections, comparing the progress with structural models in real-time. 5G technology supports the process by offering high-speed communication and precise localization, improving both the safety and flexibility of the assembly process.

Use-Case

The demonstrator is a groundbreaking aid in the construction industry for building complex structures. From 2018 to 2021, workshops analyzed market conditions, technologies, and standards, exchanging experiences across various disciplines. Three use cases were developed addressing the interfaces between planning, manufacturing, and building operation. These three use cases are: Building Operation Monitoring, Quality Assurance and AR Assembly Support.
