[vic burg]

I would say that there is a reference point that the referees can use to determine if the robot is over 80", is there not? I believe that if a robot is higher than the ball sitting on the bars, than it should be ruled as over 80". Granted, the bars are at 6' 6" (78"), and the ball is 40" (if I remember correctly), so therefore, if the robot extends to the middle of the ball, than it is at least a borderline of 80" or higher, and if the robot can go above the ball, or can reach the top of it, than it is definitely taller than it should be. (this is referring to a robot that has fallen over. As in, the robot went to turn the corner, and he tips over, and he reaches the full length of [his] half of the field. and of course, if there is a ball laying on the ground, this would help to determine it.)
Thus, a penalty should be called if the robot can reach the top of the ball or higher. At least, that is my opinion. However, it is, ultimately, up to the referees.
