Outline of Research at the Start

計測系が人に干渉しない運動解析システムの実現により、ロボットが人の細やかな技能運動を模倣できるようになることを実証する。まずロボットを介さない運動解析装置を実現するため、作業用の道具にセンサを埋込む力覚検知技術を開発する。次に道具使用中の力加減を力覚センサから取得し、位置情報をモーションキャプチャから取得する運動解析システムを開発する。そして本システムを用いて力と位置の情報に基づく接触状態の特徴量を抽出し、その情報を入力として人の高度な技能運動を再現する模倣学習を実現する。

Outline of Final Research Achievements

We developed a new motion analysis technique to capture the nuances of human skilled movements without mechanical interference. Key achievements include: (1) A compact, high-performance force sensor comparable to commercial sensors. (2) A segmentation algorithm using time derivatives of force/torque signals, effectively segmenting skilled motions. (3) Imitation learning utilizing frequency information from force sensor responses, enabling accurate force detection and real-time force control during skilled tasks.

Academic Significance and Societal Importance of the Research Achievements

既存の運動解析システムが持つ力学的な干渉の問題を克服し、人の繊細な技能運動を正確に解析・再現できる新しいシステムを提案した。小型で高性能な力覚センサと、力・位置情報から動作を分節化する手法、力センサの周波数情報を活用した模倣学習技術によって、これまで困難であった繊細な力加減を伴う高度な技能動作の解析と再現が可能になった。人の技能の解析はロボット工学のみならず認知科学や理学療法学、スポーツ工学等に応用しうる技術であり、学術的意義が大きい。
