The Design and Research of Obstacles Testing

System Based on Ultrasonic

Abstract

In practical work, there are many environments which not suitable for human to work in, then using intelligent robots to finish these works instead of human is a very good choice, however these environments are often very complex, the Intelligent-Robots-Automatic-Obstacle-Avoidance-System will become a key technology, ultrasonic have extremely strong anti-jamming ability to electric field, magnetic field, light signals, etc, so it can be used in very complex environment, the principle of ultrasonic testing obstacle is and it easy to be applied, so it was widely used in Robot-Obstacle-Avoidance-Systems, this topic designed a kind of ranging circuit using ultrasonic and test and ysis of the circuit, realizing the function of obstacle detection the distance and displayed by LED, and puts forward a method of using software fixed voice speed, it is more and more accurate than using sensors.

Key words: Ultrasonic ranging; Obstacle detection; Robot obstacle avoidance
