1. Preliminary Design Review Group A3: HMS “Bloodhound” Matt Morris Matt Prygoski Jay Slaggert Fred Thwaites Dan Zibton Thursday, April 10, 2008

2. Previous Week’s Action Item #1 -Calibration of Speed/Turning of Vehicle - Unable to do so (motors had not been mounted) - Changed plan: -Created user interface including keypad commands and LCD menu options. -Programmed function to determine vehicle location.

3. User Interface 1. Locate2. Operate 3. Traverse4. Search 1. Hazard Location 2. Starting Location 2. Operate: Full traverse and search algorithm (project goal) 3. Traverse: Traverse field only 4. Search: Perform search algorithm only

4. Determining Location Sample GPS Receiver 5 or more satellites in view? 30 samples taken? Average coordinates and store to memory Yes No Record Coordinates

5. Previous Week’s Action Item #2 -Documentation - Completed abstract, executive summary, and website -Website contains documentation, virtual model, design reviews, and much more http://www.nd.edu/~me463a38

6. Current Status of Concept - CAD model complete - Physical prototype essentially complete - Working on electrical components and software - Schedule Status: Behind Schedule -Wanted vehicle moving by now Solution: Lots of work these next few days, focusing on completion of individual design requirements - Showstoppers: None Currently (but still suffering from previous week’s showstopper)

7. CAD Model Full Model

8. CAD Model Exploded Drive System

9. Physical Prototype Vehicle Drive System

10. Next Week’s Action Items - Electrical Component Preparation for Display -Hazard Sensing -Driving Straight -Turning -Autonomous Control - Development of Vehicle Operation Code -Integrate GPS function and navigation -Perform each function (locating, driving, turning, sensing)

11. Operation Flow Chart
