Every ball intake I ever designed had a linear speed that at least matched our robot in high gear forward speed. This allows all the balls to clear the intake at the speed you're travelling so you don't start plowing them and pushing them out of the way. |

Re: Intake Conveyor Ideal Speed
on the exterior 3" wheel, that would be over 71000 RPM. Scary.

Here's a little video of a prototype we made, it's pretty fast but it could be even better once the compression distance is fixed right and belts are tightened. |

Re: Intake Conveyor Ideal Speed
So just to be clear...
We are planning on using 1" diameter rollers with belts on them, and a 10fps drivetrain. We therefore are shooting for 15fps linear speed on the belts, which would mean a roller speed of ~3400 RPM. Does this seem right/plausible/safe? *We are using 2" wide urethane orange belts with 3D printed crowned pulleys on the drive axle. |

Re: Intake Conveyor Ideal Speed
I don't think liftoff should be ruled out.

It is also important that your FUEL elevator be fast enough to keep up with your intake, so FUEL doesn't jam. My team made that mistake in 2012. |

I would use a vex planetary gearbox so you can adjust your reduction ratio after building the robot. Honestly, I think you'll want a medium speed, but...

Re: Intake Conveyor Ideal Speed
Good discussion,
I'm thinking that we're going to use a 10:1 Versa Planetary reduction with a 775 for our intake and elevator. With 31 RPS, I think we'll be intaking fuel pretty fast. Although I'm worried that we wont have enough power to lift palls up our elevator. Any experience with this? Also, if we have wheels on our roller (1/2 shaft) how would I incorporate them into my calculations? Specifically on JVN. |
