156A Week 10
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Prototype design has been decided upon. Prototyping begins in Week 10.
Accomplishments from Previous Week
Decided on a design for the system
Made a CAD for a prototype
Asked sponsor about unknown details.
Visited sponsor's workspace.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Construct prototype
Finish Individual Component Analysis
Finish Risk Reduction Report
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Wants to be able to remove brush system so it can be used for more than just arms and leg.
Design has been modified to consider a removable frame.
Sponsor will be placing the device on a 15"x28" table.
Design has been modified to consider these parameters.
Sponsor informed us that the chair she will be working with is adjustable.
Design no longer is concerned with changing elevation under the conditions of being used on a leg.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Reconsider components chosen for analysis. Think about critical subsystems rather than easy to research components.(David Gillett - 3/3)
Have adjusted choice of component analysis
Consider alternatives to pulley and track design, i.e. a creative solution not the obvious solution (David Gillett - 3/3)
Will still use pulleys, but no track in an effort to reduce noise. Multiple pulleys/belts on one shaft will provide stability.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
