Definition of a HURDLE:
When a TRACKBALL CROSSES a FINISH LINE while passing above the OVERPASS and then contacts either the floor or another ROBOT before re-contacting the originating ROBOT.

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 from the sounds of things, although this is just speculation on my part, if the ball fully passes the plane of the finish line while in the possession of a robot, it will not count as a hurdle.
