Also, I believe rourke is correct, let us parse the wording.

Note that a ROBOT attempting to HANG a GAME PIECE on the RACK will be immune from a "pinning" violation as long as it is clear that the ROBOT is continuing to attempt to HANG the GAME PIECE.

Note that the Robot is attempting to hang a game peice. They are "immune" to a pinning violation. I assume that immune means that they will not be called on them. The robot being discribed is clearly the one scoring as the last one states that it is as long as it is continuing to attempt to hang.
