RGB-SQGrasp enables robust robotic bin picking by inferring local superquadric primitives from a single monocular RGB image, overcoming limitations of depth sensors and partial views. The framework achieves a 92% grasp success rate on a UR5e manipulator in cluttered, real-world environments.
Key insights
- Superquadric primitives offer a compact and interpretable shape representation that enables graspability-aware reasoning, which is crucial for synthesizing stable robot grasps.
- Strategic integration of vision foundation models with a monocular RGB camera can effectively generate robust depth maps and instance segmentations, mitigating sim-to-real gaps and real-world depth sensor limitations.
- A hybrid neural network architecture combining local (DGCNN) and global (PointNet-adapted) feature extraction is highly effective for accurately inferring superquadric parameters from partial point clouds.
