  1. Robot Navigationwith 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.

  5. Technical Resources • www.navtechgps.com • GPS option • www.junun.org/MarkIII • Control board documentation • www.oopic.com • Documentation of Micro controller • http://studentweb.tulane.edu/~jreasor • Project similar ours


  6. 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

  7. 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

  8. Proposed Design • GPS Receiver/Compass • Microcontroller • Hobby RC Truck

  9. Proposed Design

  10. Design Validation • Garmin 15L Wired Gps 1. Small 2. Affordable 3. Accurate 15 m • Garmin Remote Antenna

  11. Design Validation Cont. • Stampede Monster Truck 1.) Large 2.) Affordable 3.) Simple • TS-025 Electronic Magnetic Compass

  12. Design Validation Cont. • Mark III Controller Board Kit (OOPic Version) 1.) User Friendly 2.) Affordable 3.) Object Oriented

  13. Economic Analysis

  14. Time Chart

  15. Management • Kris Horn : GPS and hardware integration. • Chris Foley: Software design, budget, procurement of parts. • Neil Pittman: PIC Microcontroller specialist and hardware design. • Michael Willis: Software design, board design.
