TRACT: Temporally Routed Action Chunks with Chronological Phase Authority for Contact-Rich Manipulation

Jiahao Liu, Kento Kawaharazuka, Tasuku Makabe, Kei Okada

Action chunking shortens the effective decision horizon of robot imitation learning by predicting multiple future actions, while conventional phase conditioning describes the current control instant. When a predicted horizon crosses a procedural boundary, assigning the current ph…

MDIR: A Task-Manifold Impedance Retargeting Method for Contact-Rich Teleoperation

Liu Jiahao, Kento Kawaharazuka, Tasuku Makabe, Kei Okada

Fixed Cartesian impedance makes contact-rich teleoperation demonstrations practical, but gains that secure progress and contact support also determine impact and force variability. We study single-demonstration controller-to-controller impedance retargeting. Given one fixed Carte…
