针对机器人比赛和电子设计竞赛中机器人寻线行走的普遍要求，提出了一种通用的寻线行走机器人的设计方法。机器人的核心控制器包括实现控制算法的DSP和用于扩展功能实现的CPLD；对来自光电检测传感器的信号采用模糊控制规则进行综合，核心控制器根据模糊控制器输出调整机器人的行走路线，最终实现机器人寻线行走。-For robot competitions and robot design competitions in the electronic search request line walking in general, a generic search line design method of walking robot. Robot controller, including the realization of the core of the DSP and control algorithms for the extensions to achieve the CPLD　from photoelectric sensor signals using integrated fuzzy control rules, the core controller in accordance with the output of fuzzy controller to adjust the walking robot line, and ultimately realize hunting walking robot.
