In the current rules the only form of allowed communication is Verbal
Teams may not use any type of communication, excluding verbal communication, with robots in play, in service or with robots serving their 30 seconds penalty time that contains information which reduces the need for autonomy in detecting the current game state of the robots, including the position of the ball, the location where the robot re-enters the Field, the orientation of the robots own or opponents goal, and the position of team members or opponents. In case of doubt that a team violates this rule, the code must be made available to members of the Technical Committee for inspection.
In real soccer, coaches often use gestures to signal information to the players.
I would like to see that we allow the Robot handlers to communicate to the players using such gestures.
What are your opinions on the matter?
