Ball Condition

[DonRotolo]

In any case, a wise team would design a shooter that was relatively insensitive to ball condition.

we were thinking of using a whell shooter but we decided to use a catapualt wich depending on the angle we shot high low and far (we also hit a mentor in the head)

We know we have to design it to use any balls, but we also thought we might be able to adjust how it is during the competition to adjust to the balls.

We also tried a catapult design and found it was more consistent, but we are still deciding what we will use. (We hit three students.)

I heartily applaud your abilities to hit mentors and students (three!). Having fun like that is an important part of the FRC season. Seriously.

The math with catapults is a bit more involved, but worth it. Catapults are much more accurate than ball shooters, as shown here.

I don't see how that video supports your statement. Can you explain, or provide something more than your word?

We have found that the catapult was more accurate, and can you show how that wasn't accurate, from the video, it looked as though it went pretty straight.

That wasn't a catapult in the video. That was a shooter. See the Triplets in 2006. If you're calling that a catapult, then you may want to look at 191's loading mechanism in 2006--that was a short-range catapult, feeding a shooter.

The balls, like anything else on the Robot and playfield, are subject to wear. Design your Robot accordingly.
