Social Implementation and Application Potential of a Signage-Integrated Autonomous Guidance Robot

Abstract

UGO Co., Ltd. develops the robot "ugo," which supports not only security and inspection tasks but also customer service and guidance activities. To date, we have equipped the robot with a multilingual dialogue system powered by large language models (LLMs), combining speech recognition, response generation, retrieval-augmented question answering, and conversation summarization to enhance service quality. Building upon this, in the current year we introduced a new function that integrates with digital signage to display supplementary information and product images. By presenting related content on signage according to user queries, the system aims to improve customer experience. Since April 2025, this signage-integrated system has been deployed in commercial facilities, public institutions, and international events such as Expo 2025 Osaka, conducting over 5000 dialogue sessions. In this presentation, we will discuss the challenges identified through real-world operation and explore future possibilities for application.
