Introduces the design of an intelligent tracking and drawing system based on the Freescale MCU MC9S12DG128.By using infrared photoelectric sensors,system can detect real-time route information.Then system steering angle and running speed can be effectively adjusted by combination of proportional control and fuzzy control methods,which realizes the dynamical control of the whole system.Based on the communication between PC and RF wireless modules,remote control is effectively realized and accurate drawing is obtained.Finally,experiment results are given to show the effectiveness of the proposed system.
