StenoVLA-3D: 3D-Aware Reasoning VLA for Navigation Through Gastrointestinal Stenoses

Autonomous endoscopic navigation requires the policy model to predict actions from texture-poor monocular observations, make safe control decisions, and retain evidence of lesions after they leave the field of view. Existing vision-language-action (VLA) models primarily rely on visual appearance and short-term context,...

EndoWAM: A Grounded World-Action Model for Generalizable Endoscopic Navigation

EndoWAM is presented, which is, to the authors' knowledge, the first WAM for generalizable robotic endoscopic navigation and introduces future grounding, which predicts task-relevant target regions in future observations from intermediate denoising features of a video world model.
