Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Preliminary Geometry of three wire frame decided
Bearing design not decided
Hall Effect sensor tests nearly ready to be performed
Manufacturing process not yet decided
Accomplishments from Previous Week
Met with entire group in person
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Create working model file of the geometry
Set up arduino to communicate with Hall Effect sensor through I^2C interface
Decide preliminary bearing solution
Decide on manufacturing process
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
12/12/12 in person
Provided some supplies to perform shape memory alloy (SMA) wire tests
Sponsor was hesitant about the current 3 wire solution and said they would like to see a physical model. Concerned about true x and true y
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Friction not considered in geometry design
Kinematic of current design could be presented more clearly (custom figures)
How important is cycle time?
explain the difference between the current control method and proposed control method
Find reason for switching from 4 wire to 3 wire design
How much does this cut costs by? Cost of each unit and total units being produced
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Would like a clearer explanation and clearer models
Risks and Areas of Concern
Importance of bearing design has increased
Control of prototype once it is built
Resources or Information Required but not Available
Schedule
End of Week 3: Finalize prototype design and begin manufacturing
Update Gantt chart.
Budget (list amount spent and amount remaining)
Spent ~$50
Progress on Report and Webpage
