Abstract

This paper presents the development and testing of a robot designed for automated inventory and 3D localization of items in high-density shelving systems. To enhance accuracy in locating UHF-RFID tagged objects by using synthetic aperture-based methods, rotating antennas are installed on the robot. This allows more degrees of freedom in antenna trajectory, by reaching large synthetic apertures that may deliver high-performance localization. The robot can navigate complex environments by utilizing a depth camera and a visual odometry system, and it can effectively avoid obstacles with the help of a Laser Imaging Detection And Ranging system. Extensive testing is conducted in a realistic shop-like scenario where tagged products are placed on either wooden shelves or hung on metal racks. The robot navigation capabilities are verified together with its inventory and localization performance for different visibility conditions of the tagged items.

带旋转天线的先进 RFID 机器人，用于高密度货架系统的智能盘点

本文介绍了一种机器人的开发和测试情况，该机器人专为高密度货架系统中物品的自动盘点和三维定位而设计。为了利用基于合成孔径的方法提高 UHF-RFID 标签物品定位的准确性，机器人上安装了旋转天线。这样，天线轨迹的自由度更大，合成孔径也更大，可以实现高性能定位。该机器人可利用深度摄像头和视觉里程测量系统在复杂环境中导航，并可在激光成像探测和测距系统的帮助下有效避开障碍物。在类似商店的真实场景中进行了广泛的测试，将贴有标签的产品放在木制货架上或挂在金属架上。测试验证了机器人的导航能力，以及在不同可见度条件下标记物品的清点和定位性能。
