Hello everyone! I was curious what style shooter everyone is going with and what the PROS vs CONS of each style are. Thank you!
Thank you! I didn’t see this so I’ll have to look into it right now.
Most of the OA teams of Chief Delphi have converged on the same shooter, which is top and bottom rollers with a gap in the middle. It generally performs the best, because it deforms the game pieces less, as they are not laterally deformed by middle rollers.
Choice on rollers has been split between a couple options (Colsons, Stealth wheels, etc), just keep in mind that the larger diameter wheels (3in/4in) are going to shoot the game piece a lot farther then smaller 2 in wheels, because of the much larger radii.

This is an inaccurate statement.
It is making the assumption that you are rotating the drive shaft of the large and small wheels at the same speed. Which is very likely not the case.
You should be calculating a required feet/second out of your shooter that will net your required gamepiece trajectory, then calculating the required surface speed of your shooter wheel, then backing that out to the shaft RPM requirement so you can gear your motors correctly.
Notes fly more similarly to balls than frisbees, because they have no lift. So if you use a ball of the same mass and same frontal area as the note and do a little trajectory math you’ll get a very rough exit velocity that you need.
