^论文字数:20520,页数:54 基于RFID的助盲寻物机器人设计与实现 关键词: 射频识别 移动机器人 栅格法 路径规划 贪心算法 Physical defects for the blind, study to help the blind to find the necessary items a mobile robot. The UP-Magic2410 as its main chip, embedded Linux as the operating system, and uses multiple threads, with integrated radio frequency identification module, ultrasonic distance measuring module, motor driver module and voice voice module. Which, through radio frequency identification module determines the target position, while the ultrasonic module for obstacle avoidance function. In this paper, grid method for modeling the environment, and the establishment of a global Cartesian coordinate system and the robot itself, the local polar coordinates. By adjusting the radio frequency identification module to read and write distance to the target dichotomy way to determine where the grid. Meanwhile, from the target and the robot Path Planning as the basis, the use of greedy algorithm, and gradually approaching the target. In addition, the robot can be in a dynamic unknown environment, found not know in advance the specific location of the target. Finally, the mobile robot simulation test to verify that the robot path planning algorithm has higher convergence, robustness and Environmental adaptability.
