| description | This paper presents an autonomous vehicle system's design,
development, and programming process utilizing QR code-
based positioning and navigation technology. During system
development, the STM32F407 microcontroller is employed to
control two motors with integrated encoders, where the PID
controller and trapezoidal velocity control method are applied
to optimize operational performance. The microcontroller
processes data received from the embedded computer and
provides feedback via the Universal Asynchronous Receiver
Transmitter (UART) protocol. The system integrates a
Raspberry Pi 4 embedded computer to process QR code
information via a USB camera, receive commands from a
remote control interface, and transmit control signals to the
microcontroller after analyzing QR code data. Additionally,
the system is designed to relay feedback to the control centre,
ensuring precise and stable operation. Experimental results
demonstrate that the autonomous vehicle can move at a stable
speed of 0.3 m/s, with an optimal QR code spacing of 0.6 m.
Furthermore, the control interface was successfully developed,
validating the feasibility of QR code-based positioning and
navigation for autonomous vehicles. |
