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:

  1. Separate Left and Right Pivot Modules are eliminated. With all modules identical, competition spares are reduced.
  2. Mass is reduced from 9.3 to 8.6 lbm per module (same basis)
  3. 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.
  4. Pivot modules look cooler.
