  1. Myoelectric Robotic Orthosis FahadAldakheel Melanie Ferguson Chad Knutsen Hamid Tavazoie Evan Topinka

  2. Introduction • How we met our goals • Recap of Device

  3. Mission Statement • Make A Difference. • The main goal is to help stroke patients recover faster and better than they are using current technology. • Range of Motion • Strength

  4. PDS Summary • Met all deadlines and goals • Electrical, Programming, Mechanical • Prototype by Friday • Goal date for prototype is March 16 • Ahead of Schedule

  5. External Search • Competitor Devices • Myomo (mPower1000) • Arm Brace • Limited to One motion and one part of body • Device moves • Comfort issues • Sensory issues

  6. External Search • Patent Search • We Have a Patent • Talked with multiple patent lawyers about the process • Make a sellable product • We want to learn the business aspect of things so we can incorporate that into how we design

  7. External Search • “Judge a Book by it’s Cover” • Make it look good • This is one of the biggest challenges • Feedback is important • Questionaire for each Customer • Functionality and looks • The more of these we get answered, the easier it will be to create a valuable product. • Patient/Victim • Therapist • Doctor

  8. External Search • FDA • Class II Device • Needs documentation and testing before it can reach the market

  9. Internal Search - Brainstorming • Arm Brace • Exercise machine • Table mount, wall mount, stand alone • Pulleys, robotic moving bar, etc.

  10. Concept Evaluation and Decision • Number of exercises- versatility • Degrees of Freedom exercised • Complexity • Weight and volume • Usability

  11. Detailed Design

  12. Electrical System Electrodes DC Motor EMG Amplifier Processing Microcontroller H-Bridge Power Supply Power Supply

  13. Electrical System Components • Motor specification • H-Bridge • Electrodes • 2 separate power supplies • Microcontroller

  14. Mechanical System • Use old pulley exercise equipment • 3D printing a pulley/spool • Mechanical stop • User Interface • Monitor on device • Ipad/Android

  15. Prototyping and Testing • Electrical components here by Friday • Still looking for old exercise equipment • Established place to work • At the end, perform Functional and Safety testing
