These discs travel about 20 feet in about 1 or 2 seconds. Plan view of disc launcher schematic. The figure shows a top view of a schematic for the disc launcher I have in mind.
Discs enter the contraption near the bottom of the figure.
A pusher plate slides the disc toward the drive wheel, which rotates at high speeds. The bumper, which is allowed to spin freely, nudges the disc toward the drive wheel. The drive wheel makes contact with the disc, causing the disc to spin and propel forward, out of the launcher. Guide rails on the sides of the disc path guide the trajectory of the disc as it moves through the launcher. Additionally, the platform and a top cover will prevent the discs from straying vertically out of the desired path.
