Alas, you won't get precise movement tracking with a tracked vehicle, because the tracks slip when turning, to a degree that depends on the surface they're on. You'd get more accurate (but still not totally precise) movement tracking with a pair of driven wheels and one or more casters, as the wheels will slip less. Also, unless the steppers are very beefy, they may not be able to deliver the peak torque required to move the tracks of a fully loaded vehicle; they may instead miss steps. It's a really good idea to make a crude test bed and run some tests before building the whole vehicle around the drive system.
