Else, if the right IR detector does not see the tabletop, rotate left 10 pulses.
Else, if the left IR detector does not see the tabletop, rotate right 10 pulses.
Else, if neither detector can see the table top, back up 15 pulses and try again, hoping that
one of the detectors will see the drop-off before the other.
