Design of Ultrasonic Obstacle Avoidance System of Fruit-Transportation Gyrocar Based on ARM

The pilotless fruit-transportation gyrocar works in the economic forest, avoiding the obstacle on the rail is the prerequisite of its safe working. An ultrasonic obstacle avoidance system of fruit-transportation gyrocar based on ARM embedded system is introduced in this article. The functions of the system are implemented. It could make the gyrocar stop when detect an obstacle and sends the information of obstacle to the monitoring client through GPRS. Through the test, the ultrasonic obstacle avoidance system performs well and reliable.
