Align-Then-stEer: Adapting the Vision-Language Action Models through Unified Latent Guidance
In
International Conference on Learning Representations (
ICLR
)
, 2026
We propose Align-Then-stEer (ATE), a framework that adapts VLAs to novel robots and tasks through unified latent guidance. ATE can handle significant domain shifts without compromising performance and compatible to Pi0, RDT, and etc.
