*156B Week 1

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Working on Individual Component Analysis 

  • Starting BOM

  • Starting CAD of solution

Accomplishments from Previous Week

• • Finished Risk Reduction Presentation

  • Talked with Posthetists from Hangar Clinic and got a good overview of process of creating a prosthetic

  • Stephen Tregoning, Gabriela's prosthetist, agreed to create cast mold of her right arm for free.

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Individual Component Analysis

    • Materials (Estelle)

    • Mechanical Design (Erik)

    • Microcontrollers and sensors (Maris)

    • Motors and actuators (Michael)

  • Order parts required, as suggested by individual component analysis

    • Check component room for any usable parts first

  • Design Proposal Presentation

    • Preliminary CAD of solution 

    • Preliminary circuitry of solution 

    • Actuators and motors needed for solution

    • Finger configuration(s)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • N/A 

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Possible addition of two ECE students to aide in our project. 

    • Discussion of how they will fit in the team has happened. Waiting more info. 

  • From Risk Reduction Presentation:

    • Do we have documentation for the Human Experimentation Trial we are doing? Answer: no. but should be ok. (03/20 - Ian Richardson)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • From Risk Reduction Presentation:

    • Have we looked at similar solutions for people with arthrogryposis? Answer: yes. But each case is different and Gabriela's case is unique. (03/20 - Maxwell Sun)

Risks and Areas of Concern

• • Will we be able to accomplish multiple grasping/pointing configurations in allotted time?

  • Will we be able to make this design easy to put on/off?

  • Will she be able to activate the design either by button or EMG sensing? 

Resources or Information Required but not Available

• • Eventually, will a PCB be a realistic option for us 

    • note: not an immediate concern

Schedule

• • Individual Component Analysis (04/06)

  • Design Proposal Presentation (04/09)

Budget (list amount spent and amount remaining)

• • Amount spent: $0

  • Amount remaining: $+1200

Progress on Report and Webpage

• • Report not started. 

  • Progress reports up to date.
