Keeping track of robot coordinates is a problematic proposition in general. A mecanum drivebase does make the kinematic calculations a little more involved than a skid-steer one, but if you are good about changing speeds smoothly and not slipping your wheels, the calculations are actually more likely to match reality. Using an encoder on each wheel, you can compute how far and in which direction the robot is traveling, and how much it has rotated.
