So the ball crosses the finish line, but is still touching the machine which does not meet this definition of a hurdle. This definition indicates that at least the machine has to lose contact with the ball before the ball has completely crosses the finish line.

Also an interesting issue comes from the crossing/crossed issue.
CROSSING: The act of a TRACKBALL or ROBOT passing through the plane defined by a line (i.e.
LANE MARKER or FINISH LINE) when it is projected vertically upwards. A TRACKBALL or
ROBOT shall have CROSSED a line when all parts of the object, while traveling in a counterclockwise
direction, have completely passed through the plane.

So I understand how the robot can still be "Crossing" into the next zones, but how does it not violate G22 crossing into the zone just previous to the machine? The machine is considered to have crossed that line for the purposes of the start of the match, and since it has not completely crossed into any zone except its home zone, breaking the plane into the previous zone should be a G22 violation.
