Possession is clearly defined. If the robot turns or reverses direction and the ball turns or reverses with the robot, the ball is in possession. One ball possession at a time.

Herding in previous years was also clearly defined as pushing balls without actually possessing them. If the robot turns or reverses direction the balls will continue in their original direction. Remember objects in motion tend to remain in motion unless acted on by other forces...

Think of herding as a bulldozer or a even a bucket loader that's only pushing balls. The bucket loader may help with small turning changes, but not if the loader reverses direction.

Again, as always get the official answer on the FIRST Q&A Forum. Our answers, while based on current or past facts, are NOT the official answer. The Q&A forum opens tomorrow. Have your team contact ask for a specific definition of herding from the GDC.
