AMBIT: Anticipatory Multimodal Body Recruitment for Bimanual Tracking on a Humanoid

A humanoid with 5-DoF arms cannot track generic bimanual end-effector trajectories with its arms alone; pelvis and waist motion must be recruited, but which motion, and when, is not uniquely determined. On a Unitree R1 in fixed double support, the set of dynamically valid recruitment strategies (pelvis pose and waist t...

SignFLIP: A Unified Model for Sign Language Translation and Generation via Stage-wise Alignment at Scale

Sign language translation and generation share the goal of bidirectional alignment between text and sign representations. However, existing approaches either treat them as isolated tasks or are only verified on limited datasets, limiting effective modeling between modalities. In this paper, we propose SignFLIP, a unifi...
