Microscale digital twinning of rubble stone masonry walls using robotic assembly

2025

Abstract

This paper presents a novel method for generating microscale digital twins of rubble stone masonry walls using a robotic construction pipeline. The pipeline integrates stone stock digitalization, stone layout planning, robotic stone assembly, and a dynamic digital twinning process. To validate the approach, a 0.7 × 0.7 × 0.4 m3 wall was physically constructed in the lab alongside its digital twin, which provided a precise representation of the wall’s microstructures. The results show that the proposed pipeline achieved accurate stone assembly with an averaged ±1.2 cm tolerance, producing walls comparable to traditional masonry in terms of compressive strength.

Robotics

Robotics is an interdisciplinary branch of electronics and communication, computer science and engineering. Robotics involves the design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics engineering, electronics, biomedical engineering, computer engineering, control systems engineering, software engineering, mathematics, etc.

Robotic arm

A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand.

Industrial robot

An industrial robot is a robot system used for manufacturing. Industrial robots are automated, programmable and capable of movement on three or more axes. Typical applications of robots include welding, painting, assembly, disassembly, pick and place for printed circuit boards, packaging and labeling, palletizing, product inspection, and testing; all accomplished with high endurance, speed, and precision. They can assist in material handling.
