Re: why sooo many bad robots in 07

One of the biggest problems my team had in previous years that hindered us the most at competitions was bad drivetrains.

1st year - used #25 chain and it broke every round
2nd year - used 4wd with the pneumatic wheels, it literaly jumped when it turned
3rd year - used kit bot with 2wd in the center, its max speed was too fast and it didnt go straight.

After being the driver on our 3rd year I decided to design a better drivetrain, and used some of Paul Copioli's advice and go for the 6wd. Our drivetrain was our strongest part of the robot last year, and it brought us to the elimination rounds for the first time. This year I made sure we focused a little on the drivetrain again to make sure it was driveable.

With a good drivetrain, it is much easier to score even if your arm is nominal, and if you cant score then you can at least defend well. I think many teams do what my team did the first 3 years and dont put much thought in how the drivetrain will actuly drive and preform.
