The design of intelligent robot based on embedded system

The design of intelligent robot is based on ARM microprocessor and AVR microcontroller which control Four-wheel drive robot. The design of the intelligent robot includes system design, the hardware design and software design. The core of master controller is composed of the processor which is S3C2440A belonging to ARM9 series and peripheral equipments of master controller consist of tracing module, sensor detection module, CMOS camera module, Wi-Fi wireless module and so on. Driving circuit uses ATmega16L, which is high-performance and low-power AVR 8-bit microcontroller, to control DC motor for speed governing and steering. Intelligent robot, using the operating system of Linux and based on PID algorithm of the C programming language, has realized automatic tracing, intelligent obstacle avoidance, temperature detection, image acquisition, wireless communications, and other functions. Intelligent robot is characteristic of flexible design, accurate control and stable operation.
