1. GPS Navigation System ET 494 - Spring 2018
By: Dylan Landry, Jordan Melancon, and Miguel Rodriguez
Advisor: Dr. Koutsougeras
Professor: Dr. Koutsougeras

2. Introduction
The overall goal is to implement a universally applicable GPS navigation system. The idea is to combine elements in the design as software and hardware to work in a synchronized manner to essentially created what is essentially an autonomous vehicle. This system should be able to work on any type of vehicle in an open environment.
Last semester :
An app was developed that can read/write coordinates to and from the GPS module.
Basic circuitry to rewire and control the motors of the RC car was done.

3. Objectives Fully combine GPS, app, and motor control
Car should be able to travel from Point A to Point B without any obstacles
Incorporate obstacle detection and avoidance

4. Parts List Detection sensors Ultrasonic distance sensor module
Range 2 cm - 4 m

5. Bluetooth Module HC - 06 Model Range of 10 meters (32.8 feet)
Works on 9600 baud for Arduino
Interfacing with Arduino and GPS module

6. GPS Module Adafruit Ultimate GPS Breakout Built-in antenna
Accuracy within 3 meters (9.8 feet)
Adafruit GPS Library for Arduino1

7. Mobile App MIT App Inventor 2 Block Code Simple Design
Real Time Testing

8. RC Car Motor Control Motor Voltage Spike off
Motor control protective Circuit
Typical Optocoupler:

9. Deliverables & Timeline
January - meet with our advisor and finalize semester plans; begin working on combining all elements of project
February - work on coding GPS, app, and motors to work together
March - be able to input coordinates and have car move on its own in open environment; begin working on object detection and avoidance
April - coding and testing object detection and avoidance
May - final testing and troubleshooting, present finished product

10. Work Plan
Our group objective is getting the GPS system to interface with the RC car and control it.
Dylan - wiring GPS and RC car components, Arduino power supply, movement for initial direction, routine to detect objects
Jordan - routine to check course, improve app with multiple checkpoints and master on/off switch, routine for obstacle avoidance
Miguel - expand control for both motors, system to control motor speed, implementing sensor into the RC car system
