Re: Design Process, What we did v. What you did?

SWEET robot.

All the presentations were looking good, but I got to the drivetrain one, and I started thinking about what it looks like you guys do.
It appears that you were indentifying what you could do (ie mechanisms) before you knew what you wanted to do. We do the complete opposite here.

I also have a few questions about how you describe a few of the drivetrains. (note: I am not trying to criticise, I'm trying to learn.)
What makes mecanum "very stable at high speeds"? Ussualy, mecanum wheels are not round, seems like that would make them unstable to me.

As per the final tables at the end of your presentation, I'm curious what you might have been thinking.
What makes a swerve slow? I realize you talk about more internal friction, but many times, a swerve is done with fewer gear stages than a comparable 6wd or mecanum.


I'm really loving the use of more complex design matrixes (matrice?) and the "look back" or judgement based on the matrix, but not the final descision based on the outcome of the matrix.

A solid design process = a solid robot. Looking good for years to come and 2011 .
