I really think there is nothing "morally wrong", a rule against, or anything that should stop your team members in the stands from communicating with the field players.

After all, they cheer don't they? That's just communicating to them that 'hey you're doing good!' or 'keep on trying!'

It happens every year, inadvertantly: You're team's driving, it's coming down to the wire and everyone on your team is yelling something like 'one more box', 'get in the endzone' or 'block that robot' and if that catches the eye of a driver or coach, there's nothing wrong with the robot then doing that. So if the team then chose to..say.. have a big green or red poster which indicated to their drivers to either 'go' or 'stop' regardless of the level of visibility of the stage members I see no problem.

And everyone has been able to do it every year, and in every game for most strategies their is an element of non-visibility of something. The only way from stopping the audience from helping would be to put them behind a sound-proof wall. But that's not what the game is about.
