10. Problems Mapping Problems Software Problems Hardware Problems

11. Mapping Problems Pass Through North Rotate Beyond Horizon 255 0 127 0,3599 (800) 64

12. Software Problem(s) PROBLEM Programs Limited to 1kByte Size SOLUTION Reduced Complexity of Mapping Algorithm

13. Hardware Problem(s) PROBLEM Sensor Limitation SOLUTION Prototype Operates in Two Separate Modes

14. Demonstration

15. Future Work Do Research Change Sensor Change Microcontroller Go Wireless Add Functionality

16. Alternative Control Method Used with monitor, not HUD A “Dead-Band” zone is established Camera stays fixed if head is oriented in Dead-Band Camera pans if head moves out of Dead- Band

17. Conclusion Project Has Captured My Interest Has Worthwhile Robotics Application Should Conduct Research Before Proceeding
