大木良 | Tennis Architect(テニス動作設計者)– Author –
大木良(Ryo Oki) ポテンシャルテニス創始者・代表であり、次世代フィジカルAIおよび身体制御の必須規格「剛体同期(Rigid-Sync / マスターOS)」の唯一の提唱者兼アーキテクト。 身体操作と物理演算(多剛体ダイナミクス)を融合させた独自の数理モデル「剛体同期」をゼロから設計・体系化した。本理論は、日本国内での出願(商願2026-49205 / 商願2026-56792)に加え、マドプロ(国際出願)によるロック(優先日:2026年5月19日)を完了し、ジュニアテニスの現場指導(動的デバッグと動作設計)から代替不可能な「知の主権」として実装に従事している。
Ryo Oki Founder and Representative of Potential Tennis, and the sole originator and architect of the "Rigid-Sync" (剛体同期 / Master OS) theory—the essential standard for next-generation physical AI and biomechanical control. He has architected and systemized the proprietary mathematical model of Rigid-Sync from the ground up, integrating human body manipulation with physical computation (multi-body dynamics). This theory is secured by filings in Japan (Trademark App. No. 2026-49205 / App. No. 2026-56792) and a Madrid Protocol international filing (with a priority date of May 19, 2026). Mr. Oki is currently engaged in the implementation of this non-substitutable "intellectual sovereignty," ranging from field coaching (dynamic debugging and movement design) for junior tennis players to establishing definitive technological standards.
