RAG-Diff: Adapting Diffusion Policies to Dynamic Constraints with Retrieval-Augmented Guidance

RSS 2026poster

Robots operating in unstructured environments must satisfy dynamic constraints that can change across tasks and even within a single execution. While diffusion policies can learn multimodal behaviors from demonstrations, adapting a trained policy at runtime to newly encountered or evolving constrain…

REPeat: A Real2Sim2Real Approach for Pre-acquisition of Soft Food Items in Robot-assisted Feeding

IROS 2024poster

The paper presents REPeat, a Real2Sim2Real framework designed to enhance bite acquisition in robot-assisted feeding for soft foods. It uses ‘pre-acquisition actions’ such as pushing, cutting, and flipping to improve the success rate of bite acquisition actions such as skewering, scooping, and twirli…
