My team and I are stumped on this one. 
we are trying to design a second launcher, but we dont know where to get started again because our first one failed desperately. would anyone care to give us a basic working design for a new launcher?
we would also appreciate a few tips on this: how can we get the Frisbee to spin as it launches? our first launcher had one wheel spinning at one speed at one side of a ‘tunnel’ and the other side is one solid piece of metal. we cannot get the Frisbee to spin.
Any help is appreciated! Thanks
Could you upload a video of your first launcher? It seems that it should work, you may have overlooked something. The problem may be that the frisbee did not have enough contact with the wheel to get it up to speed. But show us your design, that way we can help you.
Look to RobotIn3Days for inspiration, and cruise the Ultimate Ascent Strategies thread for ideas.
What type of launcher are you shooting for? 1 wheel, 2 wheel, pneumatic…
We discovered that a pneumatic wheel is key for any sort of effective wheel shooter. Once balanced, we were able to spin our wheel much faster, and the pneumatic wheel seems to expand a little bit due to centrifugal force as it spins, which allows it to grip the Frisbee much better.
My personal bias is to build a skeet type shooter as I have seen some really promising results from them, but that’s me 
Our shooter is a one wheel design and a conveyor system that pulls the frisbee into the wheel. We can hit the 3 point goal very accurately.
