Intelligent Drug Delivery Vehicle System Based on STM32

In the context of the new coronavirus epidemic, medical systems throughout the world has suffered tremendous pressure, the most intuitive problem is a shortage of human resources. In this regard, the ' intelligent drug delivery vehicle ' puts forward a feasible scheme, which can replace manual work in a specific hospital area to complete the delivery of drugs. The system is based on STM32F103ZET6 core processor, controlling the OpenMV visual module to identify the hospital corridor information, and then through the pressure detection module, gray detection tracking module and angle sensing module information, the core processor controls the motor drive module to make the vehicle move. The system modifies the algorithm under the traditional NCC template matching algorithm, and uses the zoom image to reduce the pixels which improve the camera frame rate and recognition accuracy. At the same time, the Bluetooth communication module is installed to enable different vehicles to execute the drug delivery operations at the same time, therefore reducing manual work saving.
