How much drifting there is on a Vex robot has a lot more to do with friction in the drivetrain than a discernable motor bias.
If you build the squarebot and you notice that it is always drifting to one side, then one of the sides of the robot has slightly more friction than the other one. If you loosen some of the parts and try to shift some of the pieces around by a few hundredths of an inch you may notice that the drift will disappear.
