Research on the development status of AGV parking robot based on patent analysis

Abstract

With the increasing severity of parking problems, intelligent parking garages are gaining popularity. By the application in intelligent parking garages, AGV robot has opened a new application scenario after industrial and logistics fields. Dozens of enterprises have developed related products. Based on patent analysis method, the development trend, key technologies, regional distribution, advanced agencies and technology roadmap of AGV parking robot are clarified, to provide intelligence support for further development of related technologies and products. Research results indicate that AGV parking robot related technologies are booming. China exhibits great R&D enthusiasm towards this field in recent years, and has applied a large number of patents. In terms of vehicle exchange technologies, mechanical arm-based exchange and board based-exchange are key R&D types. In terms of vehicle guidance schemes, laser navigation, magnetic navigation, electromagnetic navigation and visual navigation are mainstream. Moreover, the improvement of driving mechanism, actuating mechanism and positioning mechanism of AGV parking robot, and the integration of AGV parking robot with stereo garage are the development trends of this field. Thus, countermeasures and suggestions are presented for the enterprises to further develop AGV parking robot related technologies.
