Rapid Object Onboarding for Autonomous Humanoid Manipulation via Foundation Models
Pipeline Architecture
The proposed pipeline achieves rapid deployment of humanoid grasping tasks by integrating three foundational perception modules: (1) Roboflow-assisted annotation with YOLOv8 for object detection, (2) 3D mesh reconstruction via Meta SAM 3D, and (3) zero-shot 6-DoF pose estimation using FoundationPose. These components form a perception stack tightly coupled with a Unity-based control pipeline and the Unitree SDK, facilitating fast, data-efficient onboarding for new objects and manipulation tasks.
The three-stage deployment workflow consists of offline asset preparation, high-frequency online perception, and a sim-to-real execution loop. Offline, images are rapidly annotated leveraging SAM-based automation, YOLOv8n is fine-tuned on this lightweight dataset, and a high-fidelity object mesh is reconstructed from a single RGB photo. Online, RGB-D frames feed through YOLOv8 for detection and FoundationPose for pose tracking, with pose output made available over HTTP at 30 Hz. The Unity-based manipulation planner consumes these estimates, generating joint command streams transmitted to the physical robot via a C++ bridge.

Perception System Assessment
YOLOv8n, trained using minimally supervised Roboflow annotation, consistently achieves [email protected] of 0.995, [email protected]:0.95 of 0.858, precision of 1.0, and recall of 0.997 on held-out validation data. The total model size is 3M parameters, with a 32 fps single-frame inference rate on CPU. Training time is approximately 11 minutes for 50 epochs, and model deployment overhead (including auto-annotation and mesh reconstruction) is minimal. These results confirm that foundation-model-powered pipelines can supplant decades-old, labor-intensive dataset curation and calibration techniques for object detection, even when constrained to commodity hardware.

FoundationPose, using SAM 3D-generated meshes as templates, achieves sub-millimeter precision (σxyz​=1.05 mm) in static conditions and maintains 100% tracking success under both dynamic and partial occlusion conditions. Rotation error is dominated by object-axis ambiguity, which does not adversely affect grasping. End-to-end tracking throughput is maintained at >15 FPS (debug mode) and scalable to 30 FPS, meeting the closed-loop control rate needs for real-world bimanual manipulation.
End-to-End Robotic Execution
In a series of five grasping trials distributed through a workspace grid, the Unitree G1 demonstrates robust 6-DoF object grasp execution without any pipeline-specific retraining, as the pipeline accurately transfers perception outputs to a Unity-optimized IK-based motion planner and ultimately to the hardware execution stack. The sampling of joint-angle sequences from Unity simulation, without explicit sim-to-real fine-tuning or domain randomization, translates to stable grasp acquisition even with subtle real-world variation. The demonstrated extension to a window glue-application scenario, involving only class/model refinement and revised waypoint trajectories, substantiates the task-general applicability of the architectural paradigm.

Pipeline Generality: Glue-Application Extension
Task generality is rigorously tested via deployment on an automobile window glue-applicator task, replacing only the mesh and class definitions. The pipeline’s unchanged architecture proves sufficient for robust execution in a substantially altered manipulation context, with validation occurring first in Unity simulation and then in real hardware.

Numerical Outcomes and Deployment Efficiencies
The complete onboarding pipeline, from initial image capture to deployment-ready grasping, is accomplished within approximately 30 minutes per object. This includes 5 minutes for data acquisition, 5 minutes for annotation, 10 minutes for YOLO training, 5 minutes for mesh reconstruction, and minor overhead for Unity scene configuration. These metrics represent an expedited alternative to traditional procedures, which typically require days for manual annotation and laser-scanning workflows. The pipeline achieves strong perception and manipulation metrics without per-object or task-specific model reengineering.
Limitations and Future Directions
The pipeline's main limitations include the suboptimal mesh quality obtained by SAM 3D for reflective and transparent objects, which sometimes necessitates fallback on manual CAD modeling. Tracking robustness, although strong under partial occlusion, degrades upon prolonged or complete occlusions exceeding three seconds, due to the simplistic YOLO-triggered tracker reset mechanism. Precise quantification of the sim-to-real discrepancy, beyond empirical success rates, remains for future work. Promising directions include enhanced mesh reconstruction for challenging materials, multi-view pose reasoning, and analytical metrics for sim-to-real fidelity.
Theoretical and Practical Implications
This modular, data-efficient approach challenges vision-language-action model paradigms by decoupling perception and control, leveraging interpretable, foundation-model-based stacking for real-world deployment. The results indicate that practical, rapid robot deployment in unstructured environments can be achieved without heavy handcrafted datasets or specialized sensors, marking a theoretical advance in methods integration and practical reduction of barriers to robot manipulation in industrial and service domains.
Conclusion
The pipeline details a tightly integrated foundation-model-based strategy for rapid, high-reliability deployment of humanoid robotic manipulation, validated in grasping and assembly tasks on real hardware. Its robustness, speed, and minimal resource requirements set a new standard for practical robot adaptation, while open limitations invite further investigation into mesh quality and occlusion recovery. The modular structure invites extension to diverse manipulation contexts, positioning it as a reference platform for foundation-model-driven robotics research and industrial application.
