We study view-invariant imitation learning by explicitly conditioning policies on camera extrinsics. Using Plücker embeddings of per-pixel rays, we show that conditioning on extrinsics significantly improves generalization across viewpoints for standard behavior cloning policies, including ACT, Diff…
The contact-rich nature of manipulation makes it a significant challenge for robotic teleoperation. While haptic feedback is critical for contact-rich tasks, providing intuitive directional cues within wearable teleoperation interfaces remains a bottleneck. Existing solutions, such as non-directiona…
Abstract: Shared autonomy is an enabling technology that provides users with control authority over robots that would otherwise be difficult if not impossible to directly control. Yet, standard methods make assumptions that limit their adoption in practice—for example, prior knowledge of the user’s…
Deep Reinforcement Learning (DRL) has achieved remarkable advances in sequential decision tasks. However, recent works have revealed that DRL agents are susceptible to slight perturbations in observations. This vulnerability raises concerns regarding the effectiveness and robustness of deploying suc…
Reinforcement learning (RL) has achieved some notable accomplishments in robotics. However, one of the major challenges when applying RL in the real world is that unexpected disturbances in local dynamics could lead to failures of policies at test time. It is necessary to learn a model capable of ad
