AtomEgo: Exploring Ego-Robot Integration for Embodied Foundation Model Pretraining

Di Wu, Dongchen Zheng, Junhe Sheng +8

Embodied foundation models are constrained by the limited scale and diversity of robot demonstrations, motivating the use of large-scale egocentric human interaction data. However,…

PVI: Plug-in Visual Injection for Vision-Language-Action Models

Zezhou Zhang, Songxin Zhang, Xiao Xiong +8

VLA architectures that pair a pretrained VLM with a flow-matching action expert have emerged as a strong paradigm for language-conditioned manipulation. Yet the VLM, optimized for…
