When both the objects and the scene change, a policy trained on LEGS-AUG data re-rendered for that target maintains task success, while the teleop baseline fails entirely.

This research presents LEGS, a hybrid simulator that combines a mesh foreground with a photorealistic 3D Gaussian Splatting background to train vision-language-action (VLA) policies for humanoid loco-manipulation without human teleoperation. The method uses a procedural motion-primitive generator to synthesize labeled demonstrations and a two-stage color calibration to align renders with the deployment camera. Policies trained on LEGS data match or exceed those trained on human teleoperation demos and outperform mesh-only baselines. The approach enables cost-effective re-rendering of demonstrations for new scenes and objects.

This research presents HERO, a modular loco-manipulation system for humanoid robots that combines large vision models for scene understanding with simulated training for accurate end-effector control. The system achieves a tracking error of 2.44cm, outperforming prior methods by 5.5x, and operates in diverse real-world environments, reliably grasping various objects.

This research introduces HumanVerse, a 500-hour dataset of open-world human loco-manipulation, and presents $\lambda_0$, a humanoid foundation model for whole-body loco-manipulation. The dataset pairs egocentric video with synchronized body and hand motion, and the pipeline aligns camera viewpoints and arm appearance while refining motion references and controller inputs to reduce end-effector errors. The model achieves 90.0% success on SIMPLE and 62.5% on real-world loco-manipulation tasks without target-task robot demonstrations.
