Four reflectinginfrared sensors were used to detect black lines and to keep the object moving along the black line. Stepping motors’s turning and rotating speed were controlled by the drive circuit, which are constituted by GAL16V8 and L298. Based on the reliable hardware design and the precise software algorithm, the object has successfully fulfilled circular movements, movements on a certain point and arbitrary curvy movements shown on the board. In order to make the design more intelligent, LCD320240 was employed as display interface, indicating the location of the painting brush intuitionistically. By bining the keyboard and DS1302 LCD, this design has also achieved coordinate points setting and movement manner selecting. The additional function of radio data transmission which is controlled by AT89C51,made available the longdistance control of the system. CPU AT89C55 and AT89C51 are separated by IDT7132 to ensure data stability and security. Key word: stepping motor, reflectinginfrared sensors, dualport RAM evaluat ion of scient if ic developm ent .
