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.

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)

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.

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!

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

Thanks.

The circumference.

Strong Necro is strong.
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.

Re: Intake Conveyor Ideal Speed

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.
