CoRe-MoE: Contrastive Reweighted Mixture of Experts for Multi-Terrain Humanoid Locomotion with Gait Adaptation
TL;DR
Humanoid robots struggle to adapt their walking and running gaits across varied terrains due to conflicting task requirements. CoRe-MoE, a two-stage reinforcement learning framework, was developed to separate gait generation from terrain adaptation, enhancing expert specialization.
✦ Why It Matters
Engineers can leverage CoRe-MoE to enhance humanoid robot locomotion across diverse terrains, improving adaptability and stability.
Key Takeaways
- Utilize CoRe-MoE for improved humanoid robot locomotion.
- Implement a two-stage reinforcement learning framework.
- Focus on separating gait generation from terrain adaptation.
- Test on diverse terrains to validate performance.
How It Works
CoRe-MoE operates in two stages: first, it learns a stable locomotion policy for natural walking and running. Then, it introduces a terrain-aware MoE branch that uses a contrastive objective to enhance expert specialization, allowing the robot to adapt its gait based on terrain characteristics.
