Yes, the gate ramp has two side to it. One side flips up when the gate is closed (the inside or the game field side). On some field gate ramps this side of the ramp has caution tape on the bottom; the side that will face the robots. (I guess the robot needs to know).
I did notice the last field I setup at NEXTFEST did not have the caution tape applied to the bottom.
