Possession - A Robot / Disc status. A Robot is considered to be in Possession of a Disc if the Robot is carrying, holding, or controlling the movement of a Disc such that if the Robot changes direction, the Disc will move with the Robot. Therefore, pushing / plowing Discs is not considered Possession; however, using concave portions of a Robot to control the movement of Discs is considered Possession.

It is not possible in all cases (including this one) to accurately determine from a single still frame whether a specific Disc is being pushed/plowed or is in Possession of a Robot.

The Robot is your image is in Possession of at least 1 Disc (the center one that is inside the Robot); the next movements of the Robot would determine whether or not the 2 outside Discs would be in Possession of the Robot.

Because the center Disc in this image is completely "filling" the concave portion of the Robot shown in the image, it is likely that one or both of the outside Discs will not move with the Robot when the Robot changes direction or moves forward. Ultimately, the Head Referee must determine whether or not a Disc is in the Possession of a Robot based on the movements of both the Robot and the Disc during the Match.
