Implementation of Pan-Tilt System for Locating Based on ARM

The purpose of this paper was to implement a cheaper Pan-Tilt System than the traditional one which based on servo. The hardware platform consisted of the module of locating perception, the s3c2440 controller and the driver of stepper, and the Pan-Tilt System could stabilize at positions at arm/Linux circumstances controlled by software we programmed. The Pan-Tilt System had higher stability of dynamic under the condition of low frequency of pulse or high subdivision, and higher precise under high subdivision. This solution of Pan-Tilt System, suited for the place of low speed or loose real time, owns values of use and reference. The strategy was put forward for improving.
