About this paper
Jun Wan, Xing Liu, Yunlong Dong
DexReMoE presents a robotic manipulation framework utilizing a Mixture-of-Experts architecture for in-hand reorientation of objects with complex geometries. The method achieves an average of 19.62 consecutive successes on training objects and maintains robust performance on out-of-distribution objects, significantly enhancing worst-case success rates for challenging shapes.
Key insights
- A Mixture-of-Experts architecture can effectively enhance robustness and generalization in dexterous manipulation tasks, especially for objects with intricate and diverse geometries.
- Combining learned point-cloud features with object category information provides a potent and low-dimensional representation that effectively guides both policy learning and expert routing.
- Dynamic, shape-dependent expert selection via a soft gating network allows for improved performance on challenging objects that typically cause failures in generalist policies.
