From the GDC:

Rule <G42> protects a Robot and any Trackball that may be in its possession during the Hurdling attempt. The Trackball is only protected while it is in the possession of the Robot. If a Robot launches or throws a Trackball, then that protection is no longer in effect once the Trackball breaks contact with the Robot. So, an opposing Robot may attempt to block a launched Trackball. But any team building a Robot that will attempt to do so should be very aware of the effects of momentum, inertia, impulse loads on long moment arms, dynamic stability, and what happens when an unstoppable force strikes an immovable object.
