Re: Rapid fuel feeding into shooter
25 in 2006 had a brilliant shooter and straight up dominated Aim High. Essentially they had a flywheel and a mill to feed the ball. Flywheel on a live axle, and then a mill that went around the flywheel on a dead axle, both were powered by different motors. The mill allowed them to control the out put of the balls effectively, and run it backwards if anything jammed. Take a look at any of their match videos.
We are currently working on a prototype that will shoot 3 balls wide with a mill that goes around it. Looking forward to the results. |

Re: Rapid fuel feeding into shooter
How many made it into the goal?

Re: Rapid fuel feeding into shooter
This was a hopper test, no shooter on it...

Re: Rapid fuel feeding into shooter
I've been pondering this over the last couple weeks, so this is what I've thought of. We're building and testing it this week. Basically the balls roll in one direction and fall down into a chute that takes them to the shooter. They are able to fall into the chute whenever they want, which helps prevent jamming.

We ditched this mixer concept for a different one, so you won't see a high powered trashcan blender on our robot this year. |

Re: Rapid fuel feeding into shooter
Maxnz-Looks like a cool design. In your drawing I see an inner radius of a circle roughly 6.5 from the center of the 2 7/8" banebot wheel, which looks to be intended for contact with the 5" dia. balls, but the outer circle is roughly 9.5" radius from the wheel center. This would not make contact with the ball that I can see so I am just curious as to the purpose of this outer radius in the design?
Thanks! Last edited by IronMustang9 : 24-01-2017 at 14:45. |

Re: Rapid fuel feeding into shooter
For those not shooting x balls wide, has anyone tried a polycord conveyor that funnels the balls from many wide to one wide?
Something like just a regular wide conveyor but with guides in it like so: / \ Do you think this has the possibility of jamming? |

You may want to look into non-straight geometries, somethings like the attached image may work better. The Y component is exaggerated, you would probably want the width change to happen over a much longer length. |

This is the concept we are planning to use, modeled at 1/3 scale with gamepieces that are affordable. This spits balls out into two streams, but if you make half of the hopper it should shoot balls out into one stream reliably. https://www.youtube.com/watch?v=kQRavPxOIM0 |
