针对基于光电传感器组寻迹的自动导引机器人，设计了传感器阵列的布置方式。根据此布置方式，提出了三个处理规则结合而成的轨迹识别算法。即使在导引线复杂的情况下，用此算法也能得出行进方向，控制机器人沿轨迹运动。甚至遇到干扰走错时，机器人也能自动纠错。

-Photoelectric sensor group based on tracing the automated guided robot designed layout of the sensor array. Under this arrangement, three rules deal with a combination of trajectory recognition algorithm. Even in the guide lines of complex cases, using this algorithm can also come to the road direction and control of robot movement along the trajectory. Encounter interference or even wrong, the robot can automatically correcting.
