Weekly Meeting 3 (11/13/18)

Posted by Rebecca Jones on Tuesday, November 13, 2018 in Notebook.

Progress Update
- Helpful to send materials by 9am at the latest on Tuesdays
- Lit review/patent search
- Oral Report
  - Contains all important progress so far
  - Components:
    - Slide 5: overview so far–includes problem statement
    - Slides 6-9: needs assessment
    - Slide 10: Project approach
    - Slides 11-12: timeline and lit review
    - Slide 13: hardware block diagram
      - Update slide: change colors to differentiate
    - Slide 14: hardware–microcontrollers
      - Should consider voltage output of arduino
      - Sampling rate of arduino: ~50 Hz
        
        Should double EMG frequency
    - Slide 15: intent interpretation-algorithm
      - Nomenclature: Not really considered pattern recognition amongst people working on prosthetics
    - Slide 16: overview of design process
- Block Diagrams
  - Intent-interpretation algorithm
    - Nomenclature taken from paper
    - Involves four paired-EMG electrodes
    - Many papers about extraction of EMG signal step
    - Should think about good features to extract
- Device in mail
  - Can do whatever we want to it
  - Also found charger–cannot damage
Questions
- Website access
  - Should give Emily access
- Letter Support
  - BMEideas
  - What is expected of us in the project space and how our team fits into it
  - Final document due in march
  - Will communicate concrete deadline
    - Soft deadline: end of semester
Future Items
