iTeach: 実環境での失敗駆動型ロボット知覚適応のためのインタラクティブ教示

原文アブストラクト

Robotic perception models often fail when deployed in real-world environments due to out-of-distribution conditions such as clutter, occlusion, and novel object instances. Existing approaches address this gap through offline data collection and retraining, which are slow and do not resolve deployment-time failures. We propose iTeach, a failure-driven interactive teaching framework for adapting robot perception in the wild. A co-located human observes model predictions during deployment, identifies failure cases, and performs short human-object interaction (HumanPlay) to expose informative object configurations while recording RGB-D sequences. To minimize annotation effort, iTeach employs a Few-Shot Semi- Supervised (FS3) labeling strategy, where only the final frame of a short interaction sequence is annotated using hands-free eye-gaze and voice commands, and labels are propagated across the video to produce dense supervision. The collected failure-driven samples are used for iterative fine-tuning, enabling progressive deployment-time adaptation of the perception model. We evaluate iTeach on unseen object instance segmentation (UOIS) starting from a pretrained MSMFormer model. Using a small number of failure-driven samples, our method significantly improves segmentation performance across diverse real-world scenes. These improvements directly translate to higher grasping and pick-and-place success on the SceneReplica benchmark and real robotic experiments. Our results demonstrate that failure-driven, co-located interactive teaching enables efficient in-the-wild adaptation of robot perception and improves downstream manipulation performance.
