Abstract

The advent of construction robotics (CR) has been rendered technically and economically viable by the proliferation of microprocessors and a decline in costs. A captivating epoch in CR has emerged, and it defies conventional interpretation. We ask how to extract the frontier research topics from patents, which countries are driving innovation in CR, and what policies are contributing to the current situation. This paper uses patent analysis and text mining to study 1831 C R-related patents and finds four clusters from the Derwent Innovations (DI) database. The patent remaining life impact (PRLI) index is calculated. The results show an increase in the number of CR-related patents annually. China leads in the number of patent publications, while the US and other patent organizations have played critical roles in the field. An improved technology evolutionary path tracing visualization identifies several hotspots. Additionally, the policy strategy matrix (PSM) analyzes the industrial stimulation policies of the two countries with the most considerable proportion, providing an explanation for predicting future technology research and development (R&D) and the direction of optimization.

建筑机器人技术的技术现状和发展趋势：专利分析

随着微处理器的普及和成本的下降，建筑机器人技术（CR）的出现在技术和经济上都变得可行。建筑机器人技术出现了一个迷人的时代，它打破了传统的解释。我们的问题是，如何从专利中提取前沿研究课题，哪些国家正在推动 CR 创新，以及哪些政策促成了目前的局面。本文利用专利分析和文本挖掘研究了1831项C R相关专利，并从德文特创新（DI）数据库中发现了四个集群。计算了专利剩余寿命影响（PRLI）指数。结果显示，与 CR 相关的专利数量逐年增加。中国在专利出版物数量上遥遥领先，而美国和其他专利组织则在该领域发挥了关键作用。改进后的技术演进路径追踪可视化方法确定了几个热点。此外，政策战略矩阵（PSM）分析了比例最大的两个国家的产业激励政策，为预测未来的技术研发（R&D）和优化方向提供了解释。
