  2. Agenda • Current State • Budget Update • Project Plan • Risk Assessment • Individual Team Member Status • Deliverables Checklist and Online Status • Rubric Review P10010: Motion Tracking Technology Evaluation

  3. Current State • Currently on track to meet our mission objectives and cover all customer needs • Unpredictable to know whether or not sensors will “walk the walk” • All major subsystems good to go • Dr. Phillips gave approval to EE components • Met with Sara one week before DDR • Test Fixtures: Mostly done- exploring additional options • Shock and Impact- biggest concern at this point P10010: Motion Tracking Technology Evaluation

  4. Current State.. cont • Design Activities still open: • Test Fixtures: • Will meet with Lamkin-Kennard on Week 1 of Spring quarter • Need to generate ideas for shock/impact testing • Order Components: (Discuss purchase requisition form?) • Drawings and Schematics for Sensors/MCUs • Build-Test Activities Needs • EE Lab Permission? • Acquisition of all items?

  7. Project Plan Comparison • Compare plan • Differences and causes? • Main differences: due to our project’s deviation from typical MSD projects (research vs final production) • What would we do differently next time? • Try to find a comparable project for benchmarking during week 1 P10010: Motion Tracking Technology Evaluation

  8. MSDII Project Plan • Start up on risk assessment as soon as possible • Start software development and testing soon, so as to enable system level testing • Test fixtures early • Allow for time to re-test in case of erroneous results • Test overall system power consumption P10010: Motion Tracking Technology Evaluation

  9. Risk Assessment Comparison • Differences & Causes • H-M-L vs. 1-2-3 Ranking Method • Addition of Total Risk column • More detailed technical risks • Sample: Sensor Risks from Concept Design Presentation vs Detailed Design Presentation: P10010: Motion Tracking Technology Evaluation
