In the SPL, teams can implement the "manual penalize" and "manual unpenalize" packets, i.e. the referees can press the robot's chest button and this will penalize or unpenalize the robot (indirectly via the GameController). Since there is no standard button in the Humanoid League, referees will most likely not know where to press a button.

In fact the referees do not touch the robots in the humanoid league,
each team supplies a handler that is responsible to handle their -
e.g. penalized - robots.

Ideally this would not be possible, but as in our scenario the
assistant referee controlling the GC must manually unpenalize a robot,
it would be kind of obvious if a robot cheats and unpenalizes itself.
