Championship Winners Drivetrains

[Jared Russell]

This is based on my recollection, pictures, talks with the teams involved, etc., so it might not be 100% accurate. Teams, please correct me if I say something wrong...

2009
67 - 6WD wide
111 - 4 wheel crab (non-coaxial), wide
971 - 6WD wide

2008
1114 - 6WD long
217 - 6WD long
148 - three-wheeled crab (coaxial), nonagon-shaped robot

2007
177 - 6WD long
987 - 6WD long
190 - 6WD long

2006
217 - 6WD long
522 - Treads, long
296 - 2WD long, two casters in the front (I think)

2005
67 - three-wheeled crab (non-coaxial). Flop bot.
330 - 6WD long
503 - 2WD long, omniwheels in rear (were the omnis powered?)

Note: The robot base dimensions changed between 2004 and 2005 from 30x36 to 28x38. You start seeing a lot fewer 6WD robots as you go back further.

2004
71 - 4WD long with mechanism to climb stairs (by articulating the front wheels)
494 - 4WD long
435 - 2WD long, with casters in front (hard to see, but I think this is right)

Before 2004 I don't have complete information...

2003
111 - Four-wheeled non-coaxial crab (with dropdown skid for turning)
469?
65?

2002
71 - 2WD flop bot with casters and "walking filecards" for pushing
173 - 4WD long
66?

Before 2002 it is very hard to hunt down quality pics.
