Training Vision-Language-Action Models with Dense Embodied Chain-of-Thought Supervision

Haoyang Li, Guanlin Li, Youhe Feng +9

Cross-embodiment transfer in vision-language-action (VLA) models remains challenging because low-level state and action spaces differ fundamentally across robot platforms. We obser…
