    "body_text": "Most reinforcement-learning exploration spends actions moving through empty space. TacEx instead decomposes a robot model's uncertainty by sensing channel and rewards uncertainty in touch. The authors report that this tactile curiosity discovered contact dynamics for grasping and manipulation without task rewards or expert demonstrations during exploration; its resulting data then supported offline pick-and-place policies and post-training of vision-language-action models. These are preprint results on the reported systems, not evidence that touch alone solves sample-efficient manipulation in every setting.",
