2011 Pivot Value Engineering

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 lb_m 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.
