Shooter Angle Issue / Please Help

[Team4166]

Our team is making a robot similar to the bot shown in the Robot In Three Days series. We were wondering if anyone knows the angle between the hopper to the shooter, or the angle at which the shooter should be in order to shoot accurately. Any and all help is appreciated.

This is dependent on where your team plans on shooting from. If your going to be shooting from right under the goal you are going to need a greater angle than if your planning on shooting from much farther out.
Some simple trig should help you figure this out.
Plus some testing to account for the amount the Frisbee drops over the shot distance.

Why not just use some Math to determine what angle to set your shooter at, depending on where you plan to shoot from?
I'm assuming that based on your post, you plan to make a "fixed" angle shooter.
Have you tried prototyping just the shooter yet already?

This is a great exercise for the students to figure out.

As mentioned above, the angle depends on where you are shooting from. As far as accuracy goes, Frisbee accuracy is either on or off. Before the stall you have accuracy, after the stall you don't. As long as you give it the power to hit the goal before stall, the angle doesn't affect accuracy significantly.
