With the goal of replacing human dispensing with simulated automatic control, reducing the time and resource consumption of artificial drug taking, an intelligent drug delivery car is designed to improve the efficiency of medical transportation. The main control module of the system adopts STM32 single chip microcomputer as the main control chip, combined with the hardware modules such as driver, K210 digital recognition, tracking and heavy trigger. Software design mainly includes the car motion control algorithm, digital recognition algorithm, serial communication and so on. At the same time, the car path function is planned in the design, the test results show that the design can realize the drug distribution function, has a certain practical significance.
