Hello FRC world! Here is the prototype shooter for our team. We are currently getting a distance of 45ft with it. Tonight (the 23rd), we are going to test our real shooter. Let us know what you all think!

Looking good!
You might want to try:
smaller wheel
Angle the whole mechanism up more for longer distance/to shoot at high goals.
At what height is the disc at 45 feet? Keep in mind the height of the goals, discs will need to be at the top of their flight or still on the rise when they reach the goal. Nice looking shooter though!
