Re: Intake Conveyor Ideal Speed
 

Personally I would have your intake and elevator on seperate motors. It's probally best if you are capable of controlling them seperatly if a game piece jam happens. This should also take some of the stress off of that 775pro (even thogh it is overkill anyway)

Re: Intake Conveyor Ideal Speed
 

You can guess how much force your intake will experience from lifting game pieces, compression, wheels on the shaft providing inertia, and a variety of other factors, but the best way to see if it will work is to prototype. If you haven't built a model of your intake with approx. the gear ratio you want, I would suggest doing that. If you don't have access to the right motor and gearbox, at least try with a hand drill on drill speed to make sure that you don't need too much torque.

Re: Intake Conveyor Ideal Speed
 

Take your shaft speed (rev/s), multiply by wheel circumferential travel (ft/rev), and you'll get the collector 'surface speed' in ft/s. Compare to robot maximum speed, ...? Profit!

Re: Intake Conveyor Ideal Speed
 

That makes sense, although I'm still unclear on what you mean by circumferential travel.

Thanks.

The circumference.

Aside from that, the 15:1 versaplanetary that we are using with 1 1/4" rollers and an orange poly belt is now throwing them over the back of our bot.

775pro on a VP 10:1 seems to devour fuel at a good rate for us.

Using Banebots blue wheels (2-3/8"), and yellow urethane round belt.
