Since we're only a second year team, those major programming tasks are quite a challenge to tackle. However, we aren't about to back down from a challenge!
In other news, you really want to do bang-bang control for your shooter speed. It's simpler to program, easier to tune, and gets your flywheel up to speed much faster than a PID.

Re: Full Court Shooting: Over 80ft total distance

1. What material are you using for the "fence" (curved wall that is on opposite side of Frisbee from the spinning wheel) in your shooter?
2. How much compression are you using?
3. Are you running your CIM at full speed (looks like you gear up the wheel to spin faster than the CIM)?
4. Any idea on the RPM of the wheel you are shooting with?

We are testing a similar design but not getting nearly the distance that you are. We don't want to shoot full court, but it may become necessary depending on how the game plays out.

Thanks.
