Retriever: Composing Closed-Loop Asynchronous Robot Programs

Linfeng Zhao, Haojie Huang, Jiayuan Mao, Weiyu Liu, Mykel Kochenderfer, Lawson L. S. Wong

Building long-horizon robot agents requires composing closed-loop pipelines -- perception, belief update, planning, and control -- whose components run at different clocks and with variable latency. Today, these systems are often assembled with ad-hoc concurrency and pub/sub conv…

Understanding and Mitigating the Video-Action Generalization Gap via Temporal Ratio

Utkarsh A. Mishra, Yongxin Chen, Danfei Xu, Yang Liu, Xi Chen, Jiayuan Mao

Generative video foundation models exhibit strong compositional priors, yet world-action models (WAMs) and video-action models (VAMs) often lose these priors after finetuning on robotic action data. We refer to this discrepancy as the video-action generalization gap. In this pape…
