Outline of Final Research Achievements |
In this study, we focused on swarm robot systems. Specifically, we focused on the implicit observer design, in which a swarm interacting with each other in a decentralized autonomous way uses sound and light devices to learn what information about nearby individuals is available, and how it can be integrated into the behavior of the swarm robot as a whole. Then, we analyzed and designed the information processing (resolution and filtering of information) for the implicit observer design through analysis and actual device verification. We presented a sound-based direction/orientation estimation method and a light-based direction estimation method, and confirmed that they can be applied to two patterns of swarm behavior.

Academic Significance and Societal Importance of the Research Achievements |
本研究の成果は,群システムに対して,各個体に設計する自律分散的な相互作用と群全体の行動の間をつなぐ技術を音や光によって具体的に提示したことである.本研究では,シミュレーション解析だけではなく,実世界実験を通じてその技術の妥当性や機能性を検証しているため,社会応用にもつなげやすい.また,本申請で設計を目指した自律分散システムは,現在の主流となっている中央集権的なシステムと比べて,計算コストや対故障性の面で優れ,生物のような群システムの設計法の解明にもつながることが期待される.
