High-Level Project Summary
The proposed stick used to walk on lines –by line tracking technique-. The stick will be made to help any blind person to reach his destination without any other support. We also equipped an ultrasonic sensor to detect an object -if it existed in lines- and avoid it by walking on another line. And we added wheels to not require any effort from the user to move the stick. Our project is based on "LINE TRACKING", whose accuracy percentage is always 70%. And we added the IR 5channel module which decreased the errors and increased the accuracy to 90%. We will upload the code on Arduino. And draw lines on the ground. Then put the robot on the starting point. And press on any key in the keypad.

Detailed Project Description
the materials that we used in our project:
wheels:- make the ability to sliding over the ground, dig in and rotate.
wires:- to connect electronic components with themselves
Body robot:- It is the one on which we install the rest of the materials and it is also called" robot", and it is the one that will lead the blind in walking.
sonic sensor:- Measure distance by using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target.
Arduino mega:- Used to write and upload computer code to the physical board
channel line tracking sensor :- Able to accurately identify black and white lines.
Frist: the method of the hardware.
1. The classic parts were joined together.
2. All the electronic components were designed in the circuit.
3. The two Li-ion batteries were wired to the motor driver.
4. The motor driver was wired to Arduino mega board.
5. The 5 Channel IR Module was connected with the Arduino board.
6. The Ultrasonic sensor was wired to the Arduino board.
7. The map was drawn, and its coordinates were specified.
8. The self-stick was connected with the classic part on the top of it.
9. The keypad was connected with Arduino.
10. The keypad was connected with the stick.
The stick was fixed in the center of the robot base
the code that will make the project make its job and move from place to anther
When we were working on this project we collected a lot of results and data.
The first thing I will start with is one of the most important pillars of the code, which is the key Pad:-
The explanation of the keypad for the stick
· "5" represents the starting point and preparation for the stick. As for the
· As for the"4", it represents room number 1, the Line Tracking system and when it is going to it, it does not need to go through any other intersection point because it is directly opposite the starting point.

As for the last two lines, they represent the rows and columns on the keypad.
As for the last line, it is for identifying the Arduino board on the keypad

Hackathon Journey
The NASA Hackathon was one of the biggest challenges my team and I faced and we are really proud of that experience. Many people came in pursuit of global qualification. We did our best for that and worked as a team.
