Prototype Small Wheeled Shooter

[Kevin Sevcik]

I'm working on getting some more quantitative results, but our preliminary results are, well, extremely promising.

Stats on our shooter prototype:
Baseplate is 1/4" lexan, unbraced. Shooter is a little bendy as a result. 2-7/8" orange wheels on 3.5" centers. Wall gap is 10.625". Theoretical top speeds are 4300, 6300, and 14000 at 12V. We're using the bright orange urethane flat belt as our sticky wall material.

For this particular testing setup, we're firing at a 19.5 deg angle, shooter was 41" off the ground and 25' from the goal. With three motors, we were nailing our cardboard just above the top of the 2 pt goal. With two motors it was landing about a 6" below the 2 pt goal.

This was testing an integrated solution with a 5 gallon bucket hopper right next to the firing wheels, so we were dragging the frisbee out from under some others. When we were hand feeding a frisbee in, it was throwing them over the top of our cheesy cardboard 2 pt goal and they were still rising. I'd say it would be about 18" above the 3 pt goal.
