Dexterous Robot Manipulation from Human Demonstrations via Contact-Anchored Retargeting and Residual Policy Learning

Learning dexterous manipulation from demonstrations is bottlenecked by data: the contact forces that determine whether a grasp succeeds are absent from every scalable source of human demonstrations. This paper builds on two observations. First, what survives the change from a human hand to a robot hand is the contact s...

Robust Deep Reinforcement Learning via Adversarial Data Augmentation for Robotic Control Under Observation Uncertainty

Observation uncertainty can drive a deep reinforcement learning (DRL) controller to select inappropriate actions even when its nominal policy performs well. This issue is especially pronounced in robotic systems deployed outside controlled laboratory conditions, where sensing and communication are affected by noise, bi...
