• Abstract summary: We present an effective end-to-end network, CMG-Net, for grasping unknown objects in a cluttered environment. We create a synthetic grasp dataset that consists of five thousand cluttered scenes, 80 object categories, and 20 million annotations. Our work significantly outperforms the state-of-the-art for three-finger robotic hands.

• Abstract: In this paper, we propose a novel representation for grasping using contacts between multi-finger robotic hands and objects to be manipulated. This representation significantly reduces the prediction dimensions and accelerates the learning process. We present an effective end-to-end network, CMG-Net, for grasping unknown objects in a cluttered environment by efficiently predicting multi-finger grasp poses and hand configurations from a single-shot point cloud. Moreover, we create a synthetic grasp dataset that consists of five thousand cluttered scenes, 80 object categories, and 20 million annotations. We perform a comprehensive empirical study and demonstrate the effectiveness of our grasping representation and CMG-Net. Our work significantly outperforms the state-of-the-art for three-finger robotic hands. We also demonstrate that the model trained using synthetic data performs very well for real robots.

  LLMs can now act as autonomous agents that interact with digital environments and complete specific objectives. accuracy is still far from satisfactory, partly due to a lack of large-scale, direct demonstrations for digital tasks. We present Synatra, an approach that effectively transforms this indirect knowledge into direct supervision at scale.
