Abstract：In this paper,a kind of obstacle avoidance mobile robot was designed.It adopted the STC89C51 MCU as the control core,the rotation of the robot was controlled by two four-phase six-line stepping mo-tors,which were driven by the special driving chip L293D.Four pairs of reflective infrared sensor were used in the obstacle avoidance module to detect obstacle position.The collected signals were processed by PID control algorithm,and the robot alarmed by the voice chip ISD1420.The experimental results show that the system is stable,the robot is able to avoid obstacles intelligently and give voice alarm automatically.
