Chenggang Shan · Computer Technology and Development · 2009
Focuses on the ultrasonic sensor principle, the realization of measuring system software and hardware and the software flow of mobile robot.The problem of detecting ultrasonic echo is settled by means of software under S3C2410 microprocessor system.Develops the system of unknown environment obstacle avoidance and navigation for wheeled mobile robot based on ARM9 and embedded Linux system.Multi-ultrasonic measuring system is realized by circulation in embedded Linux system driver modules.Implements robotic monitoring and obstacle avoidance in uncertain circumstance with driver procedures and robotic platform system is to motion perfectly in uncertain circumstance.
