A good strategy will be to make a jig and put it along the solid black
outline of the mat.  Then align your robot with the jig.

There are couple of things we followed over the years: (1) Not to rely on
the walls in the base.  Remember the mat may be taped to the table and not
aligned as per instructions.  And you cannot move it at competition. Rather
use the markings/jig in the base to align your robot starting position. (2)
Not to rely completely on the wall for positionng the robot on the field.
Yes, we did position the robot using the wall, but only when it was further
away from the base (say towards the east end).

One year we were running the robot along the wall.  Things worked fine on
our practice table.  Walls were smooth.  At competition, the wall has a
prior hole drilled for some screw and the screw was removed.  This
left imprefection on the inner face of the wall, and our robot was
deviating from its path.  Our team got a valuable lesson.

Sachin.
