Motor calibration

[douglas_sm]

I have a problem to do the NXT walk in a straight line.
He is always hanging to one side, I tried to switch engines and wheels, sometimes a little better and sometimes worse.
Is there a routine to calibrate the motors of NXT?

That is a problem i'm also having NXT. I even checked it out in other programing languages (NXT-G and RobotC) and they have a similar problem, with the robot turn slgihtly to the right side if you put both motors to turn to the same direction with the same speed/power.

I believe this may be a recurring problem with everyone that tried to make the NXT drive forward in a straight line.

We even tried to calibrate the motors for some while, but due to schedueling problems we had to stop to do so.

Does anyone have worked on a solution for this problem?
