Another question: What have you guys done in the past to make the robot strafe straight?

Any help is appreciated!!! Thanks.
Your wheels should appear as an x-shape when you look at the robot from the top.

We have found that even weight distribution, motor bias and wheel roller tightness all affect the ability the strafe straight.
