Ball Possession

[2010FRC1261]

G43 states that a robot can only possess one ball at a time.

Can you please comment on how this applies or does not apply to a robot who is 'herding' two or three balls on the front end of the robot?

I might assume a robot can push around as many balls as possible as long as they are not in 'possession'. Though if herding two or three balls and the robot backs up on the goal ramp and the balls remain in the same relative position due to gravity, would this be considered possession?

If a ROBOT is simply pushing a BALL up the ramp in front of the GOAL and is not otherwise maintain positive control of the or position of the BALL relative to the ROBOT, this would not be considered POSSESSION.
