"智能多功能小车设计与制作：以智能模式为核心的创新技术应用"。

Intelligent robots are the new products of modern society and represent the future development direction. They can operate automatically in a specific environment according to pre-set patterns, achieving expected or even higher goals without the need for human intervention. This design focuses on the intelligent mode of a multi-functional robot car, with theoretical schemes, analysis methods, features, and innovative points that have significant reference value. The robot car can also serve as a development target for toys, helping to improve the technological content of the Chinese toy market, generate economic benefits, and create commercial value. The entire robot car platform is primarily controlled by a 51 single-chip microcomputer, enabling automatic control of forward movement, stopping, and driving. Through infrared sensors, the car can autonomously cruise and avoid obstacles. The design adopts a research method of comparative selection, independent modules, and comprehensive processing. By reviewing a large amount of related literature, analyzing and organizing relevant information, different solutions are proposed and compared, followed by selecting the optimal solution based on practical considerations for design. Finally, each successfully debugged module is integrated into the car body, combining with the program. Through the control of the microcontroller, the modules are effectively integrated to achieve the expected goals, completing the final design and manufacturing process to enable the robot car to operate intelligently in a specific environment. Keywords: intelligent, infrared sensor, automatic tracking, comprehensive processing.
