The door is behind the Alliance Station wall--this could cause the robot to be leaving the field. Matter of fact, the FIELD section makes this even more clear in 2.2.2 that it would most likely be leaving the field.

So now we get to reference rules:
--G1, Blue Box Item D. Unsafe play, consistently extending outside field. Disabling offense.
--G27. Robot contacting anything outside field. Disabling offense.
