果蔬采摘机器人自主定位与导航设计——基于RFID和WSN信息融合

将RFID与WSN技术的信息融合后应用于采摘机器人的自主定位与导航中,结合两者的优势,使采摘机器人在与外界交互上更加精准快速。RFID射频识别技术是一项新兴技术,对于采摘机器人在复杂及障碍物比较多的环境,采用RFID模块对物体的识别具有使用寿命长、识别标签多等优点,但同时也存在抗干扰性差、通信距离过短、过于依赖读写器采集信号且成本高等缺点。WSN技术能感应周围各种的信号,具有辐射范围广、可无人值守且成本低等优点,但对于识别传感器标节点、使用寿命及能耗上不太理想。两项技术之间的完美互补使智能识别与定位更上一个台阶,必将推动RFID和WSN在智能采摘机器人方面的应用和发展。

Autonomous Positioning and Navigation Design of Fruit and Vegetable Picking Robot-Based on Information Fusion of RFID and WSN

The RFID and WSN technology of information fusion to together used in picking robot self localization and navigation, by combining their advantages, the picking robot in and outside interaction of more accurate and rapid. Ra-dio frequency identification ( RFID) is an emerging technology, for picking robot in the environment more complex and obstacles, the RFID module of object recognition is the use of long life, identification tags, etc. . But there are also poor anti-interference, communication distance is too short, too dependent on the read and write device signal acquisition and cost advantages and shortcomings. WSN technology can sense a wide range of signals, with a wide range of radiation, no one on duty and low cost advantages, but for the identification of sensor nodes, the use of life and energy consumption is not ideal. The perfect complementarity between the two technologies enables intelligent recognition and positioning of a higher level, and will certainly promote the application and development of RFID and WSN in the intelligent picking ro-bot.
