LoopWAM: Closed-Loop Generalist Policy Improvement from Deployment Rollouts

Scaling expert demonstrations alone does not enable generalist robot policies to improve from deployment. Real-world rollouts contain successes, suboptimal behavior, and failures: imitating every recorded action can reinforce poor behavior, while filtering out failures discards evidence of physical interactions and the...

SkillMemo: Expert-guided Skill Memory Framework for Compositional Embodied Manipulation

Skill-Based Memory (SkillMemo) framework is proposed that implicitly decomposes long-horizon demonstrations into latent atomic skills and integrates skill-level features into a dynamic episodic memory bank for solving compositional tasks and consistently enhances both DP and VLA backbones.
