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

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

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
