This page is intended to be a discussion of improvements to be made to the 2011 Pivot Drive.
Some background (ppt).
Zipped drawing files (SolidWorks).
Pivot side plate drawing (pdf).
Pivot module top & bottom plates - zipped drawing files (SolidWorks).
The outcome of this Value Engineering effort was:
- Separate Left and Right Pivot Modules are eliminated. With all modules identical, competition spares are reduced.
- Mass is reduced from 9.3 to 8.6 lbm per module (same basis)
- Cost (calculated on FRC robot rules basis) is reduced from $1,502.89 (for (4) pivot modules) to $1,362.71 - in spite of the fact that most components purchased without spec change increased in price, year-to-year.
- Pivot modules look cooler.
