The proposed method builds upon Vision-Language-Action (VLA) models, which typically attach an action module to a Vision-Language Model (VLM) backbone and optimize the full policy jointly. However, this design leaves the action module to learn physical motion almost from scratch, resulting in a lack of explicit motion prior. The authors argue that this limitation forces early optimization to simultaneously discover temporal action dynamics and cross-modal alignment, a challenge that is further amplified in cross-embodiment settings. To address this issue, the researchers propose to pretrain the action module with motion priors, which can provide a more effective and efficient way to learn cross-embodiment robot manipulation. The pretraining process allows the action module to learn from a large dataset of motions, enabling it to develop a strong prior for motion generation. This prior can then be fine-tuned for specific tasks, allowing the model to adapt to new environments and embodiments more effectively.
