    "body_text": "Robot demonstrations are usually segmented by hand or by feeding expensive multi-camera video into multimodal models. KiRoSe instead learns a discrete vocabulary of localized kinematic events from joint and motion trajectories, then trains an open language model to interpret those token sequences. Against human labels, the authors report higher F1 than baseline segmentation methods, zero-shot transfer to unseen robot bodies and egocentric human motion, plus progress tracking and reversal detection on an unseen robot. The abstract does not provide a universal margin, and the vocabulary learns from available subtask annotations. It is a compact companion to video, not evidence that motion alone captures every semantic boundary.",
