God save Azza. 🏎️


Table of Contents

Overview

  • Azza is a line follower robot and it's target is to finish track as fast as possible
  • There is a mobile App that helps Azza to find straight lines to run with the max speed. The app communicates with Azza by bluetooth
  • Azza can accomplish this by utilising a combination of closed-loop controllers such as PID and a variety of conditions
  • 🎉 This project ranked 1st place among 7 teams.
  • This project is built using.

Parts

APP

  • App finds straight lines to help Azza drive with the highest speed
  • App should be fixed while running
  • App is built using flutter and uses Dart FFI to connect to image processing code
  • Image processing code is built using C++
  • A red & yellow paper help us to know front and back od the car. Front of the car is red. Back of the car is yellow.
  • Path of App

    • Click to expand...
    Screen Description
    • Start Screen
    • Press start button to use app
    • Connect to the bluetooth
    • Most of time it will HC-05
    • Take picture to the track when it is empty
    • You can zoom in or zoom out
    • Press on camera when you want to take picture
    • You can zoom in or zoom out
    • When press on camera start streaming and detect car on straight road or not
    • Output:
      • 0 => not in straight road
      • 1 => in straight road
      • 5 => can't find car

    Note: Mobile should be fixed while running program

  • Result of image processing

    • Input Output

Car

  • Azza receive output from app if found 1 drive with the fastest speed if 0 drive with original speed
  • Azza is able to tackle the line following problem using an array of sensors
  • Azza can accomplish this by utilizing a combination of closed-loop controllers such as PID and a variety of conditions
