MetaWorld-X: Hierarchical World Modeling via VLM-Orchestrated Experts for Humanoid Loco-Manipulation
Learning natural, stable, and compositionally generalizable whole-body control policies for humanoid robots performing simultaneous locomotion and manipulation (loco-manipulation) remains a fundamental challenge in robotics. Existing reinforcement learning approaches typically rely on a single monolithic policy to acquire multiple skills, which often leads to cross-skill gradient interference and motion pattern conflicts in high-degree-of-freedom systems. As a result, generated behaviors frequently exhibit unnatural movements, limited stability, and poor generalization to complex task compositions. To address these limitations, we propose MetaWorld-X, a hierarchical world model framework for humanoid control.
Executive Impact & Key Metrics
MetaWorld-X's innovative hierarchical control framework significantly advances humanoid loco-manipulation by integrating world models, human motion priors, and semantic-driven expert composition. This leads to unprecedented performance gains.

Semantic-Driven Expert Orchestration for Robust Loco-Manipulation
MetaWorld-X's innovative approach, leveraging a VLM-supervised Intelligent Routing Mechanism (IRM), effectively mitigates multi-skill conflicts and significantly enhances compositional generalization. This allows for the dynamic and adaptive execution of complex loco-manipulation tasks, leading to more natural, stable, and versatile humanoid control policies compared to traditional monolithic or purely model-based methods.
