单片机系统课程设计 智能小车(避障及循迹的设计 Abstract Smart as a new product of modern society, it is an important direction of future development, it can be according to the predetermined pattern in a specific environment of automatic operation, without human management, can achieve expected goal. This design mainly reflects the multi-function car intelligent mode, the theory in the design of scheme, analysis method and special features and innovation point of intelligent robot, intelligent home appliances such as the design of automatic semi-automatic robot and popularity have certain reference significance. The smart car design mainly by the single chip processor as the core, through infrared remote control to realize the car moving around, as well as to the car function mode conversion; Through the infrared sensor, achieve the function of car obstacle avoidance and tracking function. Independent design USES contrast to choose, module, integrated processing methods. Combined with actual situation comparing scheme to design and choose the optimal solution. From the infrared remote control, infrared tracking and obstacle avoidance, are in strict accordance with the scientific rigorous attitude to complete. Through debugging test module, get the correct output signal, realize its function. Finally combine the modules of various debugging success on car body, combined with the program, through the single-chip microcomputer control, to effectively integrate various modules together, achieve the expected goals, complete the final design and production, can make the car intelligent operation in a certain environment.
