Introduction • How we met our goals • Recap of Device

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

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

External Search • Competitor Devices • Myomo (m. Power 1000) • Arm Brace • Limited to One motion and one part of body • Device moves • Comfort issues • Sensory issues

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

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

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

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

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

DETAILED DESIGN
