- Data Sources and Analytical Methodology: A Foundation for Insight
The research draws upon two primary academic databases to ensure a robust and representative data foundation: the China National Knowledge Infrastructure (CNKI) database and the Web of Science (WOS) core collection. These platforms are recognized for their extensive coverage and strong academic representation, capable of comprehensively presenting research progress and outcomes in related fields globally.
For the CNKI database, the professional search was configured for the time period from January 2015 to June 2025. Filters were applied to include only full-text articles, online first publications, and synonym expansion. This initial search yielded 358 results. After removing documents without authors and those irrelevant to the theme, 193 usable articles remained for analysis.
Within the WOS core collection, an advanced search was conducted for the period from January 2015 to July 2025. After refinement processes, the literature count stood at 567 articles. Following a manual removal of off-topic publications, 446 articles were retained. Subsequent deduplication using the CiteSpace software resulted in a final count of 411 articles for international analysis.
The core of the methodology involved employing CiteSpace software, version 6.1R6, for visual analytics. This tool transforms vast literature data into clear and intuitive knowledge maps. By combining qualitative research with quantitative analysis, the study constructed a knowledge map for the household service robot domain, thereby revealing the current state of research and developmental dynamics. This approach is instrumental in tracing the evolution of the China robot research ecosystem.
- Research Findings and Detailed Analysis: Mapping the Global and China Robot Landscape
The application of CiteSpace’s country co-occurrence module for analyzing publishing nations revealed a network of 58 nodes and 199 links. In the national co-occurrence map, China emerged as the leading contributor with 114 publications, followed by the United States with 61, Japan with 58, and Italy with 55. This indicates that China holds a position of considerable strength in terms of publication volume within the household service robot research field, a positive signal for the underlying China robot innovation base.
Keyword cluster analysis, a method that groups thematically similar keywords based on their co-occurrence relationships, was applied to both domestic and international datasets. This technique helps distill representative thematic structures and highlight research hotspots.
Based on the CNKI literature from the past decade, a keyword cluster knowledge map was generated in CiteSpace. The network comprised 11 clusters and 275 nodes. The clusters from the domestic (CNKI) data were largely interpretable, reflecting research interests within the China robot academic community.
A parallel keyword cluster knowledge map was constructed from the WOS data. The results showed clear cluster structures with high overall clustering quality. For a synthesized view, the fifteen identified clusters from the international data were further consolidated into three major categories: Robot Technology and Application, Artificial Intelligence and Human-Computer Interaction, and Quality of Life and Healthcare. This categorization aligned with the keyword taxonomy, validating the accuracy of the analytical approach.
The analysis reveals that the primary research hotspots in household service robots over the past decade, both internationally and within the China robot context, include robot technology, human-computer interaction, and artificial intelligence. However, a distinct divergence is observed in emerging focus areas. Internationally, recent years have seen a surge in research on social robots developed in the human-computer interaction field, assistive devices for people with disabilities, rehabilitation robots, and robots focused on aging populations—specifically in elderly healthcare, daily living assistance, and caregiving.

Many enterprises within the China robot sector face urgent needs to enhance their core technology patent reserves, brand recognition, and product differentiation. This necessitates a synergistic advancement of technological innovation and brand strategy to drive industrial upgrading.
- Analysis of Research Frontiers: Tracing the Evolution of Focus
Burst keywords—terms whose frequency increases sharply over a specific period—hold significant value in analyzing research frontiers. Due to the limited volume of domestic research literature, extracting burst keywords from the CNKI database was not feasible for this analysis. Therefore, the examination focuses solely on burst terms identified from the WOS core collection.
After removing keywords unrelated to the research theme, the burst analysis of WOS literature data shows a clear temporal evolution in research focus. In the period from 2015 to 2019, international research was comparatively more concerned with foundational robot hardware and performance technologies, such as mobility, recognition operations, knowledge representation, and tracking. From 2020 onwards, the research frontier shifted markedly. Assistive robots for the elderly and people with disabilities, social robots, elderly care robots, along with subjective robotic domains like deep learning, perceptual systems, and artificial intelligence, have become prominent research hotspots. This shift underscores a global trend towards human-centric and application-specific robotics, a trend that the China robot industry must closely monitor and integrate.
| Aspect | International Research (Based on WOS) | China Robot Research (Based on CNKI) |
|---|---|---|
| Primary Research Strength | High maturity in quality of life & healthcare applications (e.g., elderly care). | Strong publication volume, active in foundational technology research. |
| Core Hotspots | Robot Technology, AI & HCI, Quality of Life & Healthcare. | Robot Technology, AI & HCI (aligned with global trends). |
| Emerging Frontiers (Post-2020) | Assistive/Social/Care Robots, Deep Learning for subjective tasks. | Less distinct burst detection; focus may be broadening. |
