  4. Develop conclusions and recommendations based on tests conducted.
  5. Work with software team to get full movement performance metrics of last years robot.
  6. As a starting point for working with gears consult:
    2007 TE Session Slide on Power Transmission (Pages 6, 7, 13 & 14)
    Wikipedia's Page on Gears
    WM Berg's Technical PDF on Gears (very comprehensive 40 mb +)

Kicker
