Re: Predicting Actual High Efficiency Goal Shooting at Worlds

1.1 out of _4__ teams will have a median H.E.G. ball count that is >50
2.1 out of _9__ teams will have a median H.E.G. ball count that is >100
3.1 out of _50__ teams will have a median H.E.G. ball count that is >200
4.1 out of _300__ teams will have a median H.E.G. ball count that is >400

I think the balls are light enough that doing 100 is pretty reasonably easy for many teams. If you consider the ability to just dump the 50 balls from the hopper into your robot, that cuts intake time down by a ton.

So assuming it takes 25 seconds lump sum for you to collect 100 balls, (5 seconds for dump and 20 seconds for ground pickup)

Also estimating the approximate time to shoot these 100 balls, assuming you are shooting at a moderate rate of 2 balls, you are looking at about 50-55 seconds to shoot all of the balls.

I think my estimated times and firing rates are really conservative estimates.

Basically 55 + 25 = 80 seconds.

I think a team that does 1 or 2 gears would still reasonably shoot 100, a robot just shooting balls could get close to 200.

However, getting 400 is a lot of black magic to me, someone broke something about the game to be able to score that much. I don't think you'll ever see the number that high.

Playing around with our prototypes/ some initial software control we have yet to find a way to get 100% accuracy on shooting more than 2 balls per second.

If anyone has better results/ think I really missed something important on my estimates please let me know!
