3D Gaussian Digital Twins for View-Robust 3D Visuomotor Policy Learning on Articulated Objects

Single-view 3D visuomotor policies based on point-cloud observations, such as 3D Diffusion Policy, often suffer from limited viewpoint generalization due to partial observability and occlusion. This is particularly challenging for articulated objects whose internal motion induces geometry changes. To address this probl...

Recursive Self-Improvement of Visuomotor Policies through Local Recovery Supervision

Visuomotor policies can execute familiar tasks yet lack the corrective behavior needed after their own mistakes. We present a framework for recursive self-improvement through local recovery supervision. Each round audits the current policy, generates corrective demonstrations at supported failure states, and uses them...
