1. Robot Navigation with GPS Kris Horn, Chris Foley, Richard Neil Pittman, Michael Willis

2. Problem Background Purpose: Design and construct a vehicle capable navigating to a sequence of path points Learn how to integrate components including GPS, compass, and vehicle into working system.

3. Needs Statement Provide vehicle capable of following a specified path Provide a platform that can be used for: Information Gathering Remote Presence Environmental Survey Provide learning experience for Team

4. Goals Interface micro controller with GPS & RC vehicle Vehicle will be sturdy enough to cover mostly flat terrain while carrying a payload of electronic equipment including the GPS. Vehicle will be able to establish its own location on earth and use information from the GPS to navigate to a user defined point. Vehicle will be able to follow a path of points provided by the user.
