5. Timeline

6. Goal 1: Understanding ZigBee Approach: What can ZigBee do? What can ZigBee do? How does ZigBee work? How does ZigBee work? Learn Software & Hardware relationship What types of inputs work with ZigBee? What types of inputs work with ZigBee? Research & look for other components Experiment with ZigBee Complete all lessons in the ZigBee Kit Complete all lessons in the ZigBee Kit

7. Goal 2a:Update Current Modules Approach: Evaluate & clean current designs Evaluate & clean current designs Bring circuit up to code Fix bugs Fix bugs High Battery Consumption No Sleep mode Make improvements and add ons Make improvements and add ons Add more I/O ports Reduce size of circuit

8. Goal 2b: Educational Kit Approach: Research Research Think like a non “techie” Make a User Friendly Kit Make a User Friendly Kit Type up a tutorial Easy to use kit for other students Simplified encoder/decoder Simplified encoder/decoder Interfaces with sensors, motors, etc. Interfaces with sensors, motors, etc. Test run kit Test run kit Receive feedback Make adjustments to kit

9. Goal 3: ZigBee Home Project Approach Identify a need Identify a need People w/disabilities, Elderly, Children Devise a prototype Devise a prototype Test it repeatedly Refine and Retest Refine and Retest Eliminate Bugs Make Improvements

10. Potential Problems Time Constraints Budget Constraints Running out of spare parts Not being able to see other potential problems

11. “Nice to Have Goals” Speech Recognition Input Reduce the cost of building modules Implement Home Project on a larger scale

12. Expectations Better understanding of research and development process Link concepts of programming to hardware Become familiar with basic networking Produce a working product to help those in need
