    "body_text": "PolyUMI combines a wrist camera, optical tactile finger, microphone and proprioceptive sensing in a wireless gripper for collecting demonstrations. Its transferable sensing finger and VisTA dataset are meant to preserve more contact information than vision alone. In the paper's experiments, touch and audio added useful signals and matched or exceeded existing policies on selected tasks; the evidence remains bounded to those demonstrations and hardware.",
