摘　　要：避障是自主移动机器人应具备的功能之一,以TI公司生产的DSP芯片TMS320VC5402为核心,采集环境信息并对智能小车进行控制,选用四组超声波传感器检测智能小车前方的障碍物,设计了智能小车的自动避障系统,并阐述其工作原理.该系统设计简单、成本低、实时性好,在室内环境中取得了预期的实验结果,使智能小车无碰撞到达目的地.The obstacle avoidance is one of the main functions that an independently mobile robot should be provided. Using DSP chip-TMS320VC 5402 manufactured by TI Company as a key component, collecting the environmental information and controlling the intelligent carriage, a kind of obstacl avoidance system of intelligent carriage is designed. In this system, four groups of ultrasonic sensors are used to detect the barries,which are front of distance between the intelligent carriage and the barriers. The system＇s design is simple, and has lower cost and better real time features. And at the same time, this system has obtained anticipated experimental results in the indoor environment. That is： the intelligent carriage can arrive at the destination without any collision.
