Design of an Unmanned Meal Delivery Car Based on STM32
The system of the unmanned delivery car consists of a small car and a human-machine inter-face.Both sections can be connected to Internet of Things platform through the WiFi module and data can be uploaded through the MQTT protocol.The operation information of the car can be viewed in real-time through the WeChat applet.The hardware system uses STM32 as the main control chip,while the K210 visual module is used to recognize numbers and the OPENMV visual module for line inspection.The drive of the wheel motor is controlled by the small car through Pl algorithm.The test results show the car can run stably,and the designed interface can display and interact normally;the cloud platform can provide real-time feedback to the terminal with the uploaded data,enabling remote invocation of cloud data and display on mobile phones,computers,and device screens.
