摘要:

多指机器人抓取的最新进展已实现快速的6自由度(DOF)单物体抓取。然而,杂乱场景中的多指抓取在很大程度上仍未得到充分探索,因为需要对障碍物进行推理,这显著增加了生成高质量无碰撞抓取所需的计算时间。在本工作中,我们通过提出DDGC来解决这些局限,它是一种快速的生成式多指抓取采样方法,能够仅根据单张RGB-D图像在杂乱场景中生成高质量抓取。DDGC被构建为一个网络,对场景信息进行编码,以生成由粗到细的无碰撞抓取位姿和构型。我们在1200个仿真杂乱场景和7个真实世界场景上,将DDGC与GraspIt!中的模拟退火规划器进行了实验基准比较。结果表明,DDGC在合成高质量抓取和清除杂物方面优于基线,同时速度快5倍。这进而为在实际应用中使用多指抓取打开了大门;迄今为止,由于其他方法需要过多计算时间,这类应用一直受到限制。

英文摘要:

Recent advances in multi-fingered robotic grasping have enabled fast 6-Degrees-Of-Freedom (DOF) single object grasping. Multi-finger grasping in cluttered scenes, on the other hand, remains mostly unexplored due to the added difficulty of reasoning over obstacles which greatly increases the computational time to generate high-quality collision-free grasps. In this work we address such limitations by introducing DDGC, a fast generative multi-finger grasp sampling method that can generate high quality grasps in cluttered scenes from a single RGB-D image. DDGC is built as a network that encodes scene information to produce coarse-to-fine collision-free grasp poses and configurations. We experimentally benchmark DDGC against the simulated-annealing planner in GraspIt! on 1200 simulated cluttered scenes and 7 real world scenes. The results show that DDGC outperforms the baseline on synthesizing high-quality grasps and removing clutter while being 5 times faster. This, in turn, opens up the door for using multi-finger grasps in practical applications which has so far been limited due to the excessive computation time needed by other methods.
