Herding versus Possession

[FRC1717]

Can a robot that is designed as a bulldozer herd a row of three balls on the front plane of the robot into a goal? Or, does the robot need to explicitly separate the balls so they can only push one ball into the goal at a time? Would pushing multiple balls as with a bulldozing robot be considered possessing the balls or herding the balls?

Would a plow that runs the legal length of the robot, on the front of the robot, be considered legal as per rule G43?

Clearly it would be designed to touch multiple balls, and through the course of play manipulate multiple balls, but it is not really capturing multiple balls... just pushing them. Is it legal in regards to the "POSSESS one ball rule".

[GDC]

There is no rule the would prevent simultaneous herding of multiple BALLS, as long as they are not in the POSSESSION of the ROBOT.
