近年来，随着科学技术和人工智能的不断发展，智能机器人、智能小车得到了越

In recent years, with the continuous development of science and technology and artificial intelligence, smart robots and smart cars have been more and more widely used. As a product of the progress of the times, artificial intelligence is the future direction of development. It can complete corresponding actions in a specific environment according to a preset pattern. It does not require human management. It can be applied to archaeology, robots, medical equipment, scientific exploration, etc. use. Especially intelligent robots (smart cars) based on wireless transmission can play a special and important role in applications such as daily life, scientific research, and operations in dangerous and complex environments. The smart car is a comprehensive system integrating environmental perception, planning and decision-making, automatic driving and other functions. It intensively uses computer, sensing, information, communication, navigation and automatic control technologies. It is a typical high-tech complex. . The smart car can display time, speed, and mileage in real time. It has the functions of automatic tracking, light finding and obstacle avoidance, programmable driving speed, accurate positioning and parking, remote image transmission and other functions. In addition, with the development of the Internet, computer technology, multimedia, electronic technology and wireless communication technology, because of people’s urgent need to obtain and exchange information anytime and anywhere, wireless communication has begun to play an increasingly important role in people’s lives. People and the information network are inseparable. Wireless communication technology has a development trend of integration, low power consumption, and easy operation. At present, some wireless communication modules composed only of microcontrollers and integrated radio frequency chips continue to introduce this kind of micro-power short-distance wireless data transmission technology that is widely used in the field of Internet of Things. As one of the most promising information technologies in this century, radio frequency technology has received great attention from the industry. The technology uses radio frequency for non-contact two-way communication to automatically identify the target object and obtain related data. It has many advantages such as high accuracy, strong adaptability to the environment, strong anti-interference, and fast operation. This design is based on the design and implementation of a single-chip smart car. The main function of the car is to autonomously identify the black guide line and realize fast and stable line-finding according to the direction of the black line. The trolley system uses a single-chip microcomputer as the control core, and uses infrared sensors to obtain external information from the environment to control the direction and speed of the trolley, thereby realizing the expected functions of the trolley.

In recent years, with the continuous development of science and technology and artificial intelligence, intelligent robots and intelligent cars have been more and more widely used. Artificial intelligence, as the product of the progress of the times, is the future direction of development, which can be set in accordance with the pattern in a specific environment to complete the corresponding action, do not need artificial management, can be used in archaeology, robotics, medical equipment, scientific exploration and other purposes. In particular, wireless transmission-based intelligent robots (smart cars) can play a special and important role in daily life, scientific research and operation in hazardous and complex environments. Intelligent car is a comprehensive system which combines the functions of environment perception, planning decision-making and automatic driving. Smart car can display time, speed, mileage in real time, with automatic tracking, light-seeking and barrier-avoidance functions, program-controlled driving speed, accurate positioning parking, remote transmission of images and other functions. In addition, with the development of Internet, computer technology, multimedia, electronic technology and wireless communication technology, because of the urgent need for information to be accessed and exchanged anytime, anywhere, wireless communication began to play an increasingly important role in people's lives, people and information networks have become inextricable. Wireless communication technology has the trend of integration, low power consumption and easy operation. At present, some wireless communication modules consisting only of microcontrollers and integrated RF chips are constantly introducing this micro-power short-range wireless data transmission technology, which is widely used in the field of Internet of Things. Radio frequency technology, as one of the most promising information technologies in this century, has been highly valued by the industry. The technology uses radio frequency to make contactless two-way communication, which can automatically identify the target object and obtain the relevant data with high precision, strong adaptability to the environment, strong anti-jamming, fast operation and other advantages. This design is based on the design and implementation of the small-chip intelligent car, the main function of the car is to be able to independently identify the black guide line and according to the direction of the black line to achieve fast and stable line-finding. The car system takes the single-chip machine as the control core, uses the infrared sensor to obtain the external information of the environment, to control the direction and speed of the car, and then realizes the expected function of the car.
