What is the hardest (yet possible) task in this year's game?

I don't know how quickly you could shoot balls, it really depends on the launcher you used, and how quickly you could feed balls to it. I think it's possible to get all 10 balls from 1 robot in the center, I think it would be difficult to get balls from multiple robots into that center goal. You would have to work an autonomous with them so that one would fire right after the other ended, or so the balls would "alternate" landing in the goal.

Since we're combining auton and normal challenges, here; a robot that can score all 10 balls into the center in autonomous (without dead reckoning), and that can shoot a ball into the center goal while moving from behind the half-court line during human controlled mode. I've calculated that a shooter at the 5' height limit firing balls at 12 m/s at a 45 degree angle could hit the target from roughly 44', neglecting resistance forces. Air resistance will decrease this, but I think you won't lose 10' due to it, so a half-court shot is do-able.

For more difficulty, it should be able to make a certain percentage of its shots as well.
