STM32-based Campus Intelligent Express Cart Design

The emergence of the e-commerce industry has greatly affected people’s daily lives and people have become accustomed to shopping on the Internet, which has put forward higher requirements for the timeliness and convenience of the express industry. In this project, we designed a campus intelligent express cart with STM32F103 microcontroller as the main control chip to solve the problem of “last mile” express of courier. The device is able to deliver the courier that arrives near the destination to the final recipient. And the device mainly has auto-tracking module, infrared endpoint module, obstacle avoidance module, ESP8266WIFI wireless module, motor drive module, display module, key module and alarm module, each module cooperate to realize express delivery. The auto-tracking module is responsible for driving and route planning, the obstacle avoidance module is responsible for monitoring the surrounding environment, when the cart encountered obstacles to take the initiative to avoid; The key module and the alarm module are responsible for protecting the security of the express delivery and the privacy of the recipient. The main control module of single-chip microcomputer is the control center of the car, which processes the information returned by each module, and receives the command signal from the terminal through the wireless modulee to realize the man-machine interaction.
