What wheel to use for the flywheel
Out team is trying to build a single flywheel shooter. Currently we are using a 4" colson performa wheel that is 2 inch wide. Despite Pid control and trying various compression, our shots are all over the place. Any suggestion on the wheel choice and the amount of compression that may improve our consistency will be greatly appreciated.
Thanks |

Re: What wheel to use for the flywheel
Have you tried putting a second, identical wheel on the same axle? Or, how about splitting the 2" wheel into two 1" wheels? The resulting "groove" should allow a straighter track through the shooter. It's not an uncommon setup for FRC shooters.

Re: What wheel to use for the flywheel
Thanks for the suggestion. We will try that tomorrow.

Re: What wheel to use for the flywheel
Colson's are too hard this year. Try a soft rubber wheel for your flywheel.

Re: What wheel to use for the flywheel
We are starting to think along those line too. I think my team build a reasonably good cage and hood for the flywheel and we have done everything we knew to tweak it. We will look at a softer wheel.

Re: What wheel to use for the flywheel
I really want to see slow motion footage of a ball leaving a shooter that has a soft rubber wheel. I'd guess that at the speed the shooter wheel spins at, there is enough centripetal force pulling outward on the wheel that it acts like a hard rubber wheel rather than a soft one.

The equalizing factor, as Clint said, may well be trying a softer wheel that allows more compression to come from the forgiving wheel rather than the balls. |

YMMV, just some results from our tests. Last edited by Fusion_Clint : 09-02-2017 at 00:26. |

Re: What wheel to use for the flywheel
Space and weight allowing, more massive flywheels can be more easily regulated using PID. Through conservation of momentum, a large mass flywheel will transfer less of its momentum to the fuel than a less massive flywheel for each shot. It will take longer to reach optimal shooting angular velocity, but will maintain that angular velocity much more easily. If it's possible you may look into that in addition to different wheel surfaces

Re: What wheel to use for the flywheel
Just for clarity, I assume Anthony is referring to these, as well as the other compliant wheels AndyMark has released this past season.
To the OP, a picture of your current setup would help us all dig into the minutia of your design and offer advice, if you so choose. |
