Outline of Final Research Achievements

The research was mainly concerned with the proposal and evaluation of wireless communication within robots. It was found that the propagation of radio waves in robot arms and legs depends greatly on the frequency, and that there are some frequencies that are very difficult to propagate. We constructed an environment that simulates the actual robot as much as possible and succeeded in acquiring the propagation in a more realistic environment. The research was accepted for publication in IEEE journals and international conferences, received the Best Presentation Award at international conferences, and was highly evaluated both domestically and internationally.

Academic Significance and Societal Importance of the Research Achievements

ロボット技術は革新的な新譜を遂げ、今や様々な応用分野を生み出そうとしている。ロボット内には多くの配線が存在し、重量、動きの制約、信頼性など多くの問題が存在する。　研究ではロボット筐体内のハーネスを無線化することで、より柔軟性の高いロボットを構築するもので元々有線接続であったものを無線化することになるので、品質としては無線でありながら有線の品質や遅延、信頼性が求められる。研究では超低遅延、超高信頼を実現する無線通信方式の開発と、ロボット筐体内の伝搬伝搬を合わせて考察することで、実用的な無線化ロボットシステムの実現が可能となった。
