The epidemic prevention robot designed in this paper uses the STM32F103C8T6 minimum system as the main control chip, uses K210 as the face mask recognition module, and is composed of a voice broadcast module, an LCD liquid crystal screen, and an infrared temperature measurement module. When the system detects that the face is not wearing a mask or is not wearing a mask correctly orthe human body temperature is higher than the threshold temperature, it will issue a corresponding voice reminder. This design has been debugged many times and can meet the actual engineering requirements. The error is within a controllable range, and it has the characteristics of low cost, customizability and high recognition.
