论文摘要
快速通过机器人抓住机器人会导致许多应用程序，这些应用利用了快速，动态的拾取和放置对象。传统上用于空中操纵器中的刚性抓地力需要高精度和特定的物体几何形状才能成功抓握。我们提出了猛禽（Raptor），这是一个四轮摩托车平台，结合了自定义的鳍射线抓地力，以实现具有不同几何形状的物体的更灵活的抓握，利用软材料的特性来增加抓地力和物体之间的接触表面。为了减少通信延迟，我们提出了一种基于快速DDS（数据分配服务）的新的轻型中间件解决方案，作为ROS（机器人操作系统）的替代方案。我们表明，猛禽在现实环境中平均达到了83％的抓地力，用于四种不同的物体几何形状，同时在握紧过程中平均以1 m/s的速度移动。在高速设置中，与以前的作品相比，Raptor最多支持有效载荷的四倍。我们的结果突出了自动化仓库中航空无人机的潜力以及其他在难以到达的地方运行时速度，迅速和鲁棒性至关重要的操作应用。
Rapid aerial grasping through robots can lead to many applications that utilize fast and dynamic picking and placing of objects. Rigid grippers traditionally used in aerial manipulators require high precision and specific object geometries for successful grasping. We propose RAPTOR, a quadcopter platform combined with a custom Fin Ray gripper to enable more flexible grasping of objects with different geometries, leveraging the properties of soft materials to increase the contact surface between the gripper and the objects. To reduce the communication latency, we present a new lightweight middleware solution based on Fast DDS (Data Distribution Service) as an alternative to ROS (Robot Operating System). We show that RAPTOR achieves an average of 83% grasping efficacy in a real-world setting for four different object geometries while moving at an average velocity of 1 m/s during grasping. In a high-velocity setting, RAPTOR supports up to four times the payload compared to previous works. Our results highlight the potential of aerial drones in automated warehouses and other manipulation applications where speed, swiftness, and robustness are essential while operating in hard-to-reach places.
