Agentic RSR: Real-to-Sim-to-Real through Scene Reconstruction and Execution-Grounded Robot Policies

A simulation of a real robot workspace must preserve task-relevant interactions, while policies developed in it must operate on observations available to the real robot. Yet scene reconstruction and policy development are often treated separately. We present Agentic Real-to-Sim-to-Real (Agentic RSR), a framework that l...

Credit-Guided Policy Improvement for Test-time Adaptive Vision-Language Navigation

Credit-Guided Policy Improvement (CGPI), which recovers signed, reference-relative decision credit from action-induced observation transitions without external outcome feedback from action-induced observation transitions without external outcome feedback is proposed.

Unordered Landmark Visual Navigation

Unordered Landmark Visual Navigation (ULVN) is proposed, a unified RGB-only framework free from temporal and odometric priors that constructs a robust 2D topological map directly from unstructured images via calibrated geometric verification and maximum spanning forest refinement.
