Fixed Angle vs. Adjustable angle Shooter

[billbo911]

Again, we too faced this same question.
Because simplicity is one of our key goals in designing our system, we really had to decide which would give us the greatest control.

We knew we already needed a way to have reliable RPM for the shooter, so we choose to go with that for our primary control over distance.

Once we prototyped a couple of different designs, we also decided to add a two position hood.

So, our final solution.......both.

My team sees a little bit of benefit to being able to adjust the angle of the shot, even if it is just 45* OR 75*, we want there to be some control over it. We prototyped some designs for throwers, and now that we've got one that we like, we're in the process of constructing a fixed 45* thrower, just to have a final, to-spec design that we can pass off to the programming sub-team. This way they can start getting the measurements they need to calibrate aiming code, and while they're doing that the mechanical sub-team will get to work on building a variable angle "hood" (for lack of better term). It should be interesting how each team solves the same problem!

We decided on a fixed angle. Our prototype shot well up close and from the top of the key at 60 degrees. We're going to try 70 degrees today to compare.
