Progress Probes : Lightweight Runtime Monitoring for Vision-Language-Action Models
Atiksh Bhardwaj, Edward W. Duan, Junwon Seo +4
Vision-Language-Action (VLA) models can perform diverse manipulation tasks directly from visual observations and natural language instructions, but they remain prone to mistakes an…
Decoding Task Progress from VLA Representations
Atiksh Bhardwaj, Edward Weiyi Duan, Prithwish Dan +2
Vision-language-action models (VLAs) are moving rapidly towards deployment as general-purpose manipulation policies, but we currently lack basic tools for understanding what these…
X-Diffusion: Training Diffusion Policies on Cross-Embodiment Human Demonstrations
Maximus A. Pace, Prithwish Dan, Chuanruo Ning +5
Human videos are a scalable source of training data for robot learning. However, humans and robots significantly differ in embodiment, making many human actions infeasible for dire…
X-Sim: Cross-Embodiment Learning via Real-to-Sim-to-Real
Prithwish Dan, Kushal Kedia, Angela Chao +4
Human videos offer a scalable way to train robot manipulation policies, but lack the action labels needed by standard imitation learning algorithms. Existing cross-embodiment appro…
