초록/해제  
요약Robot learning has made significant strides in enabling complex manipulation skills across a variety of tasks. Yet, a central challenge remains: achieving generalization. Current methods often falter when faced with unseen objects, novel embodiments, or varying environments. This dissertation addresses this challenge through data-centric approaches to enhance the generalization of robot manipulation policies, focusing on three pillars: the combined use of simulation and real-world data, training-time data augmentation, and test-time adaptation. The core thesis is that strategically leveraging and augmenting data leads to robot systems that are more data-efficient, robust, and adaptable.The first two parts investigate training-time strategies using simulation and data augmentation to build robustness into the policy. This includes bridging the reality gap through self-supervision and co-training across simulated and real-world domains, augmenting data to simulate varied robot morphologies and camera viewpoints, and leveraging simple single-arm demonstrations to train coordinated bimanual policies.The third part introduces test-time adaptation techniques that avoid costly retraining. I present methods for adapting to new objects, transferring policies across diverse robot arms, rapidly imitating novel tasks with transformers, and enabling zero-shot grasping via multi-modal models-allowing robots to handle novelty in tasks, objects, and embodiments.Through extensive simulation and real-world experiments, this dissertation shows that data-centric methods-simulation, augmentation, and adaptation-can enhance generalization across tasks, objects, and embodiments, while making robot learning more robust and efficient.
