OK, so I finally got my act together and cleaned up the last two drawings, and folded them in with the rest of our white paper describing of our updated gearbox design. The "Mark 2" version of our gearbox is smaller, lighter, has fewer moving parts, and is easier to manufacture than the previous version. It is also updated to incorporate the new Bosch motors included in the 2003 FIRST kit of parts. The updated design has been posted in the
White Papers section of the board.
We used this gearbox design successfully during the 2003 season in Richmond and Annapolis, and it performed well. We also used it this past weekend at the Maryland State Fair competition, when we were running and our treads weren't binding (due to a different, and completely frustrating, problem - next year we go with WHEELS!!!). Anyway, we hope this is useful. Let us know if you use, or improve upon, the design. Have fun!
