During the round, can the robot protrude into the player box?

I believe you also asked this question here

please see rule <G28> in update 3 which states:

<G28> If any part of a robot is in a Ball Corral (breaks the vertical plane of the
diamond plate of the Wall), a referee will throw a 10-point penalty flag. The robot
operator and the human player have a shared responsibility to avoid contact. If a team
member touches the offending robot, that teams’ robot will be disabled. If a robot
pushes another robot to break the plane, the pushing robot will be assessed the
penalty. If a human player touches a robot that has been pushed into the Ball Corral,
the pushing robot will be disabled.
