5 motor drive

I would like to know if its a good idea to run a 5 motor drive, it would conisnt of Four blue motors(400-450 rpm) on a 36:60 drive train with one 5.5 wattmotor on each side. Im asking because my conveyor cant run at 5.5 wats and I need to take part of the 88w max and move it to the conveyor

Why would you need the extra 5.5s? A 4 motor drive works perfectly fine for this season. Our team runs a 4 motor drive with Green motors, six wheels, and a 60:84 gear ratio, and we have had no problems with the drivetrain.

What do you mean by this? Why would you need to “take part of the 88w max”?

Middle school? Yeah
High school? Not really…

He’s saying he wants to use more motors on his intake so he’s taking them from the drivetrain.
However, a 1 motor intake and 1 motor wall stake mech should work fine. Maybe we can help you troubleshoot.

And yes, our team is a high school team and my teams first year.

Yes, That is what I mean. But for my lady brown mech, I need a high speed separate motor on the conveyor. I have a 5.5 for intake, 11 for conveyor, and 11 for arm and 66 for drive. Its at 93.5 watts but the max is 88 wats so Im not sure what to do.

a 4-motor drive will get pushed around like crazy. we have a 6-motor wheelbase and we have a tier 1 climb, a wall stakes mech and a two stage intake, so be careful how you use your motors and you should be fine. also try reducing friction on your conveyor we run ours 5.5 and it works fine.

My apologies, a 4 motor drive is probably not the best, as I said before. Our team runs a 4 motor, and for the most part we drive good, but we may get pushed around, I don’t exactly remember. We run 44w for drive, 11 for intake, 11 for conveyor, and 11 for Lady Brown.

you should watch the FUN interview of the jugglenauts because they have a pretty good 55 watt drive where there are 4 600 rpm motors and 2 5.5 watts where the 5.5 watts are geared up to 600 rpm in a 3:1 ratio.

not necessarily. we ran a 4 motor drive (green motors w/ 4in wheels if I remember correctly) last year and it worked fine. sure, we weren’t the pushiest bot on the field, but it was enough to prevent other teams from bullying us around too much.

also, kinda unrelated, but how did you get your conveyor to run well on a 5.5w?
I have mine running on 1 full motor and even that had overheating issues (its fixed now but it took a lot of tuning). mine is a one-stage system (with the intake, conveyor and hood all running on the same motor), but even so, I dont think any one part of my system would work with 1/2 of the power.

Rly because now the meta for overall vex games are 6 motor 66w drives or more with pro.

Our robot has a 333 rpm four motor drive and we haven’t been pushed around much, even by high school teams. It might also help that our robot is 14.5 pounds…

we use a no friction tensioner. basically just some spacers on a screw that tensions the chain. we have probably a 90% percent success. we then can have a wall stakes mech.

that is a uncommon occurrence. most of the top teams use a 6 motor drive.

yeah i think it worked because we id direct drive green motors w/ 4in wheels, which has more torque than most setups. the lower speed didn’t come into play much since our main advantage was our ability to quickly and consistently launch triballs, and our ability to climb at an early event (it was only tier a or b, but since nobody else had one that worked, we got the highest level ascent bonus).

so basically, 4 motor drive isn’t an ideal choice, but it can be effective with the right setup.
