SLA: Can Spatial Pretraining Improve VLA Robot Manipulation?
Can a robot policy learn better three-dimensional control without running a geometric model every time it acts? This episode of *Embodied AI 101* examines how SLA uses spatial supervision during continual pretraining and downstream adaptation. We cover three questions: how OmniVGGT features become training targets for a VLA; why the alignment-on versus alignment-off scaling experiment matters; and what the RoboDojo-Real leaderboard establishes about the resulting system. The discussion spans simulated bimanual manipulation in RoboTwin, perturbation testing in LIBERO-Plus, and physical…
