Description

国内の宅配便取扱個数は年間50億個に迫る．効率化や人員不足対策の新しい手段として，ラストワンマイルを担う自動配送ロボットの利活用は重要な課題である．その一方で，予測が困難な自動配送ロボットに対する衝突が懸念されており，ロボットと人が快適に共存するための仕組みについて検討することが喫緊の課題である．そこで本研究では，自動配送ロボット周辺の歩行者の不安低減を目的とし，Augmented Reality（AR）を活用した情報提示について提案する．実験では，提案手段の有効性を検証するために自動配送ロボットが屋外を走行する筑波大学に5Gアンテナを施設し，スマートフォン上に9種類のARコンテンツを表示するシステムを構築した．実験の結果，パーソナルスペースの侵害や物体の近接を事前に可視化するARコンテンツが周辺歩行者の不安感を低減することを確認した．

The number of parcels handled in Japan is approaching 5 billion per year. Utilization of automatic delivery robots, which are responsible for the last mile, is an important issue as a new means of improving efficiency and countermeasures against staff shortages. On the other hand, there is an urgent need to study a mechanism for comfortable coexistence between robots and people, because of concerns about collisions and accidents that may occur when automated delivery robots run in unpredictable directions. In this study, we propose an Augmented Reality(AR) based information presentation system to reduce the anxiety of pedestrians around an automated delivery robot. In order to verify the effectiveness of the proposed method, a 5G antenna was installed at the University of Tsukuba, where the automated delivery robot runs outdoors, and a system was constructed to display nine types of AR contents on the smartphone. As a result of the experiment, we confirmed that the AR contents that visualize the invasion of personal space and the proximity of objects in advance reduce the sense of anxiety of pedestrians in the vicinity.
