So then this robot can still turn and maintain it's shot without having to move? I understand this, but is this 87 inches enough to vary your shot?

For the JVN bot, what's the distance from the robot to the apex of the trajectory, and what's the length of the sweet spot? Armed with that knowledge and a bit of high school geometry, you can get an idea who's faster, the goalie or the shooter.

I presumed that the angle for the was small... I was incredibly wrong. With that setup, he has 60° of shooting, and the goalie has a distance of 20 feet to guard (assuming that they are a perfect spot. Even being in the general are gives them 10-15 feet along the goal in which they can shoot. This just seemed so small to me, but now this area is large and effective. Thank you
