Tonight, we did some more rotator tests, this time in both positive
and negative directions. The results indicate that things are behaving
rather nicely, but there is an increase in commanded voltage with a
decrease in velocity that is not linear, but increases more as the
velocity decreases more. The postive and negative directions seem about
the same, except the negative tracks had a |voltage| about a 1000 less
than the positive tracks.  The table of results follows:
