    Default Hurdling question

    We had a question regarding hurdling:

    In the rules Crossing is defined as:
    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 counter-clockwise direction, have completely passed through the plane.
    Hurdle is defined as:
    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.
    Hurdling is defined as: HURDLING:
    The act of completing a HURDLE. To be considered in the process of HURDLING, the ROBOT must:
    • be in its own HOME STRETCH, and
    • be in POSSESSION of a TRACKBALL, and
    • be moving toward the OVERPASS and/or elevating the TRACKBALL so that the top of the TRACKBALL is higher than the LANE DIVIDER.
    Rule <G11> is defined as:
    Each TRACKBALL that HURDLES its own FINISH LINE will earn 8 points (2 points for
    CROSSING the FINISH LINE and a 6 point bonus, yielding 8 points total).
    So with all of this in mind, imagine that a team remains stationary inside the first quadrant under the overpass and next to the divider wall and has an arm that is holding the trackball at the end of it which is extended above the middle of the lane divider (i.e. higher than 8ft. 4in.). Then they rotate this arm so that the ball completely crosses over the 1st quadrant and into the the 2nd quadrant where the claw drops the ball but then picks it up again and then swings the trackball back into the 3rd quadrant and into the 4th quadrant and finally back into the 1st quadrant again. Whereupon they repeat the entire process again.

    Now according to the rules, the robot has never crossed a line since not all of it ever completely entered a new quadrant. But the trackball has crossed into each quadrant since its entirety has been in each quadrant at a given time.

    Each time the trackball is completely swung over its Alliance's overpass the claw releases the ball so it bounces on the ground before it is picked back up again, and the entire process is repeated over again.

    The Trackball has moved counter-clockwise and has fully entered into each quadrant. It has touched the ground each time it passes over it's own overpass. Therefore we believe it meets all the requirements for Hurdling.

    As long as there is an open passing lane around the robot at all times it would not be considered to be blocking.

    Also, the robot never exceeds the imaginary 80in. cylinder.

    In this scenario described above, were all the actions legal?

    Is this a legal maneuver?

    Thanks,
    Team 2158

    Default Re: Hurdling question

    As described, this would be a legal maneuver if it was possible to do it without violating Rule <R16> at any time. We must note, however, that any Robot attempting this maneuver would not be protected under the provisions of Rule <G42> (as the Robot no longer satisfies all the criteria of Hurdling) and any opposing Robot could interfere with the maneuver without Penalty. Furthermore, if any opposing Robot in the opposing Home Stretch raises a Trackball above their Overpass, and it is then impacted by your Robot or Trackball while conducting this maneuver, then you would immediately be Penalized under Rule <G42>.
