UMI-3D: Extending Universal Manipulation Interface from Vision-Limited to 3D Spatial Perception
Summary: arXiv:2604.14089v1 Announce Type: cross
The Universal Manipulation Interface (UMI) has revolutionized the way data is collected in the field of embodied manipulation. However, its dependence on monocular visual SLAM (Simultaneous Localization and Mapping) has presented significant challenges, particularly in environments where occlusions, dynamic scenes, and tracking failures occur. In response to these limitations, we are excited to announce UMI-3D, a cutting-edge multimodal extension of UMI that incorporates 3D spatial perception capabilities.
Overview of UMI-3D
UMI-3D is designed to enhance the robustness and scalability of data collection by integrating a lightweight and cost-effective LiDAR sensor into the wrist-mounted interface. This integration facilitates LiDAR-centric SLAM, which allows for accurate metric-scale pose estimation even in challenging real-world conditions.
Key Features of UMI-3D
- LiDAR Integration: The inclusion of a LiDAR sensor significantly improves the system’s ability to navigate and map environments that are prone to occlusion.
- Multimodal Sensing Pipeline: UMI-3D features a hardware-synchronized multimodal sensing pipeline that aligns visual observations with LiDAR point clouds.
- 3D Representation: The system produces consistent 3D representations of demonstrations, enhancing the quality and reliability of the collected data.
- End-to-End Pipeline: UMI-3D supports a comprehensive pipeline for data acquisition, alignment, training, and deployment while maintaining the portability of the original UMI.
- Open Source: All hardware and software components are open-sourced, promoting large-scale data collection and accelerating research in embodied intelligence.
Performance and Applications
Extensive real-world experiments have demonstrated that UMI-3D achieves high success rates in standard manipulation tasks. Moreover, it enables the learning of tasks that posed challenges or were infeasible for the original vision-only UMI setup. Notably, UMI-3D excels in:
- Large deformable object manipulation
- Articulated object operation
This advancement signifies a substantial leap forward in the capabilities of robotic systems, allowing them to perform more complex and varied tasks in dynamic environments.
Conclusion
UMI-3D represents a significant advancement in the field of embodied manipulation, extending the capabilities of the Universal Manipulation Interface from vision-limited to a robust 3D spatial perception system.
