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

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.

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

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.

Technical Resources GPS option Control board documentation Documentation of Micro controller e.edu/~jreasor Project similar ours

Design Constraints Budget Must be cost effective Time Deadline  End of Semester Technical Scope Approach may not be too challenging for team to complete before deadline

Environmental & Societal Impact Effects on Warfare Used for mine detection Removing humans from danger Safety & Environmental Concerns Minimal Careful Path selection to prevent collision Proper disposal of battery packs Proper Maintenance of electrical components
