Re: The Game Breaker

I don't think we'll see many precise and accurate half-court shooting robots, let alone full-court shots.

The precision is difficult due to the differences in the coefficient of restitution (aka squishiness) of the basketballs; each ball is slightly different, and each ball changes at different rates as they are picked up, fired, run over, etc. on the field. While the balls will likely all be in similar new condition at the start of the competition, over the course of the competition some balls will be (ab)used more than others and replaced by attrition, thus leading to big differences in ball quality by Saturday.

The accuracy is difficult due to the cone of error of lining up your shots from 25-50' away. Being off by 5 degrees from the fender will probably not cause your robot to miss a shot; but the same error from across the field may as well be a mile.
