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 (mPower1000)
• 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
Electrical System
Electrodes
EMG Amplifier
Microcontroller
Power Supply
H-Bridge
DC Motor
Power Supply
Processing
Electrical System Components• Motor specification• H-Bridge• Electrodes• 2 separate power supplies• Microcontroller
Mechanical System• Use old pulley exercise equipment• 3D printing a pulley/spool• Mechanical stop• User Interface• Monitor on device• Ipad/Android
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
