## 3 Analysis and Results
### Visualization Analysis of Journal Distribution  
Based on the journal co-occurrence diagram and the data from the top ten most productive journals, it can be seen that research in the field of construction robotics is primarily concentrated in a few key journals, exhibiting a clear trend of domain clustering. As shown in Table 5. _Automation in Construction_ (AUTOMAT CONSTR) is the journal with the highest number of publications, with 160 articles, which far surpasses other journals. This journal focuses on automation technologies in the construction process, including construction robots, building automation systems, and more, making it a leading platform for theoretical research and technical applications in this field. The large number of articles published in this journal reflects the broad attention construction robotics research is receiving, especially in areas such as automated construction, smart buildings, and BIM. \begin{table}

Table 4: Top 10 countries by number of publications. _Advanced Engineering Informatics_ (ADV ENG INFORM) ranks second, with 75 articles published, highlighting its importance in the construction robotics and related fields. This journal covers topics in engineering informatics, including data analysis, the application of information technology in engineering, and more. As a high-tech application, construction robotics is widely studied in this journal. With the growing demand for digitization and informatization in the construction industry, this journal provides a significant platform for the integration of advanced technologies in construction. _Journal of Construction Engineering and Management_ (J CONSTR ENG M) ranks third, with 72 articles published. This journal focuses on the management and practice of construction engineering, covering aspects such as construction management and the coordination and scheduling of building projects. As the construction industry transitions toward smarter management, the application of construction robotics is gradually penetrating construction management, further emphasizing the importance of automation and robotics in this area. In summary, research in the field of construction robotics is mainly concentrated in areas such as automation, robot control, construction management, and information technology. High-impact journals in these fields provide essential platforms for the exchange and development of these technologies. As shown in Figure 4. The distribution of journals and publication trends show that research in construction robotics is moving toward more efficient and intelligent solutions, gradually integrating with practical application areas such as engineering management and construction [37]. With the continuous advancement of technology, future research is likely to focus more on the integration of construction
