PhyFilter: Physics-Based Feedback Lets Robots Generalize Without Massive Data

Researchers from Beihang University and NTU propose PhyFilter, a plug-and-play physics-informed filter that corrects neural network errors using real-time robot state feedback and known differential structures, enabling zero-shot generalization across quadrupeds, drones, aerial manipulators, and acceleration estimation with only flat-ground simulation training.
