Sigh, did not think I would be digging through my senior design project papers tonight (As an aside this is quite humbling, I recommend to anyone who has already graduated college!)


From what I remember, our frisbee launcher was consistent to within +- 3 inches at 30 feet distance between 3 and 10 feet off the ground (when shot from around 3 feet). We used an 11 inch wheel connected to a cim motor that was spinning at 1000 rpm, and we'd put in a new frisbee in each time it was back up at 1000, which was within 2-3 seconds. The keys were putting a groove into the spinning wheel to grab the frisbee, covering the wheel with rubber foam, and then having a rigid outside wall with a straight path at the end, so that the frisbee would go straight when it left the launcher.

I'll now have to dig through our derivation of equations, but from what I remember it's not physically difficult to build a good launcher, the difficult parts are 1.) getting frisbees into the launcher, 2.) getting the software to aim it.
