    "body_text": "Robot policies are normally treated as the output of training, not as objects with a distribution of their own. This study compresses the parameters of Unitree G1 control networks into a latent space, then trains a Diffusion Transformer to model and generate those latents. The authors report that sampled networks can be deployed for real-world motions including walking and dancing. They also identify a repeated structure in first-layer weights that tracks the robot's kinematic prior, appearing in policies produced by both reinforcement and imitation learning. The result does not mean arbitrary robot intelligence can be summoned from noise, and the abstract supplies no broad safety or reliability guarantee. It does suggest that a family of trained controllers may contain learnable regularities tied to embodiment—patterns that can be generated and inspected rather than rediscovered from scratch each time.",
