Use the P89C51RA as a key component, collecting the environmental information and controlling the intelligent carriage, a kind of obstacle avoidance system of intelligent carriage is designed. In this system, infrared obstacle avoidance sensors are used to detect the barries,which are front of distance between the intelligent carriage and the barriers. The systems 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.
