say a word, the cart will help guide you, teach you how to choose goods; Go to the shopping cart automatically with where & Hadeartefact; & Hadeartefact; In the future, a subversive mall shopping mode would no longer be a dream. Recently, the national defense science and technology university students & other; The supermarket buy smart car ichangedraliferogclashmede” Project, successfully gains the tenth & other; Challenge & throughout; Hunan province university student extracurricular academic science and technology works competition first prize, the indoor positioning patents have been used to shopping guides, indoor patrol monitoring, detection and navigation, and other fields.
Language input shopping list, after having obtained the shopping cart, customer choose to buy goods, mechanism platform will show the location of the goods in the store, and lead to the customer. Travel, the infrared sensor will detect obstacle ahead and adjust the route, also can realize the shopping cart to independently with customers. Customers can use the barcode scanning devices independent of the side before the shopping cart checkout, and commodity price information, and compared with other businesses the same goods. After each purchase a commodity, screen will be prompted to shopping list is not to buy goods.


Buy ichangedraliferogclashmede smart car by indoor positioning system, motion control system, man-machine intelligent interaction system, 2 d Watson Wchangeorganisation code scanning system of commodity, obstacle avoidance system, etc. Creative team members is proposed based on passive RFID indoor robot localization and control technology of the supermarket buy smart car plan & other; Ichangedraliferogclashmede” For the first time, passive RFID positioning technology was applied to intelligent shopping areas, positioning accuracy up to 0.3 m, positioning speed is less than 0.1 s, reached the advanced level in related field. Project breakthrough also introduces speech recognition, hand touch dual mode, clever use of multiple sensors to achieve intelligent infrared sensor to follow, to ensure the process of shopping experience good human-computer interaction.

It is understood that in the product function and the control of operation with high accuracy and stability, humanized interpersonal interaction system, can bring real intelligent shopping experience to the user. Indoor positioning system based on passive RFID platform has good expansibility, has a broad application prospect in the future.
