Some teams are experimenting with other
firing mechanisms. A straight up shooter isn't necessary to score.
However if you're thinking of a dunking mechanism, this is not possible this year as even with full extension your robot cannot reach the baskets (see spoiler for math explaining it)
(Disregard and see EDIT)
Best of luck, and I hope this was helpful
EDIT: Oops, I really need to be more careful before talking in absolutes. The math above only applies from dunking from the side parallel to the driver station. The other sides of the fender can be dunked on.
