Pivot Drive Value Engineering - 22-November-2010
- Ran a Value Engineering session on the 2010 Pivot Drive.
- Value Engineering Slides (ppt) including "Straw Man" proposal for modular Pivot Unit.
Wooden Man - 28-November-2010
- Based on feedback to the "Straw man" proposal on 22-November, an improved "Wooden Man" (pdf) design was developed to elicit further critique.
Scoring Models
Scoring Calculator that tallies individual and overall autonomous score, raw peg, uber-multiplied and logo bonus scores, race scores, and penalties into an overall match score. 9 Jan 2011, Siri.
Scenario Model allowing side-by-side and step-by-step comparison of 2 teleop scoring scenarios. 11 Jan 2011, Clem.
Strategy & Design
Results of the team's Game-Play Strategy Development sessions are available. 12 Jan 2011, Clem
Note that <G19> in The Game RevA appears to clearly rule out "the Strangman" Minibot strategy. 12 Jan 2011, Clem

Pivot Drive
Email to Programming Team: Last year, angle sensor orientation and wheel orientation were arbitrary. We dealt with this by installing a custom potentiometer panel which allowed a correction bias to be set to align the wheels. Since our 2011 pivots will be modular, I propose that we calibrate the sensor to the wheel during assembly. Sensor output would then be fixed versus wheel angle relative to the pivot module. Since each installed pivot module has a specific orientation within the robot chassis, the sensor output would also be fixed versus wheel angle relative to the robot chassis as well (although not identical for all pivots). The need for on-robot pivot angle calibration should thereby be eliminated. Regards, Clem (15-Jan)
Email to Programming Team: Pivot control mathematics utilize the values of the robot wheelbase length and width. DEWBOT VII is expected to have a somewhat different wheelbase than DEWBOT VI. DEWBOT VI Wheelbase: 21.5 in (wide) x 28 in (long) DEWBOT VII anticipated Wheelbase: 20.75 in (wide) x 30.75 in (long) The mathematics for Pivot Drive are described in papers posted at: Pivot Wheel Documents Bien cordialement, Clem (15-Jan)
