Research questionHow can direct vision-language-action robot policies capture multi-timescale dynamics without learning undesirable behavior from mixed-quality deployment trajectories?Behavior cloning may reuse trajectories with very different outcomes without separating useful dynamics from undesirable behavior. Its representations may also fail to preserve how scenes and tasks evolve across multiple time horizons.

It adds training-time predictive objectives and a value critic over deployment trajectories, with evidence reported on three simulation benchmarks; these auxiliary components are not used during online action generation.research paper · Sep 2, 2026
