Robots are learning how to give you a sponge bath or scratch an itch by 'dreaming' about it after reading descriptions of how it feels.

The Takeaway
This bypasses the need for massive, dangerous, or impractical real-world datasets for physical human-robot interaction. By using generative models to build 3D training grounds, robots can learn complex social and physical skills entirely in virtual space.
From the abstract
Developing autonomous physical human-robot interaction (pHRI) systems is limited by the scarcity of large-scale training data to learn robust robot behaviors for real-world applications. In this paper, we introduce a zero-shot "text2sim2real" generative simulation framework that automatically synthesizes diverse pHRI scenarios from high-level natural-language prompts. Leveraging Large Language Models (LLMs) and Vision-Language Models (VLMs), our pipeline procedurally generates soft-body human mo
