- 요약To achieve human-level dexterity, robots must master contact-rich interactions with the physical world. The crux of contact-rich manipulation is making contact in the right places, at the right times, and with the right forces. Advancing contact-rich robot manipulation requires designing methods that focus on these most fundamental elements of contact. Towards this claim, this thesis presents novel grasp prediction, trajectory optimization, and imitation learning methods designed specifically for contact-rich interactions. We show that, compared to baselines, our methods improve the contact-rich manipulation capabilities of robots because they explicitly consider how to make contact in the right places, at the right times, and with the right forces. First, we consider the contact-rich task of interacting with articulated objects, where robot motion is constrained by the moving parts of objects. We design a grasp prediction model that centers on making contact with articulated objects in the right places. We show how combining our grasp prediction model with compliant control enables robots to robustly interact with articulated objects that have varied local geometries, articulation axes, and joint states. Next, we consider dexterous manipulation, where robots must apply precise and coordinated forces across multiple contact points. Within this setting, we explore both analytical and data- driven methods. On the analytical side, we show how discrete contact planning can be used to enforce making contact at the right places and times within contact-implicit trajectory optimization (CITO). Our method plans more robust dexterous manipulation trajectories than a general CITO baseline. On the data-driven side, we present a method that leverages force sensing to compute robot actions for policy learning that apply the right forces. These force-informed actions improve policy learning for precise and coordinated dexterous manipulation tasks like opening an AirPods case and unscrewing a nut. Together, these contributions show how tailoring grasp prediction, trajectory optimization, and imitation learning methods to focus on precise contact brings robots closer to human-level dexterity. Still, many challenges remain for robots to achieve the same levels of generalization and robustness as people, particularly in contact-rich settings. To conclude, we share some future directions for continuing to improve contact-rich robot manipulation.
