The best chance is to herd opponents trackballs whenever the chance presents itself. Basically, give it a shove in the wrong direction whenever you see it. This is slim pickings. It remains to be seen how the judges will view deliberately moving in front of herding robot.

The definition of POSSESSION a trackball is quite clear, as well.

Code:
POSSESSION: Controlling the position and movement of a TRACKBALL while the TRACKBALL is
supported or captured by an ALLIANCE shall be considered POSSESSION of the TRACKBALL. A
TRACKBALL shall be considered “supported” by a ROBOT if in the estimation of a reasonably
astute observer the majority of the weight of the TRACKBALL is being borne by the ROBOT. A
TRACKBALL shall be considered “captured” by a ROBOT if, as the ROBOT moves or changes
orientation (e.g. backs up or spins in place), the TRACKBALL remains in approximately the same
position relative to the ROBOT. Both the “supported” and “captured” conditions include the case
where the TRACKBALL is also in contact with the floor.
So, if a team bumps a ball and it rolls away from them, they are considered HERDING and not in POSSESSION.

Code:
<G29> POSSESSING Opponent’s TRACKBALLS - ROBOTS may not be in the POSSESSION of a
TRACKBALL belonging to an opposing ALLIANCE. A PENALTY will be assigned for each
violation. HERDING of an opponent’s TRACKBALL and removing an opponent’s
TRACKBALL from the OVERPASS is permitted.
