Yep ot is me again. I was wondering if anybody has any input on holonomic drive. We will be running a 4 wheel system, we created gear box’s. Our gear ratio is 5:3. I was wondering if that will be good enough for clean sweep

I’m guessing that you are one of Mr Cotter’s students and that he has already told you how important it is to search for information before opening a new thread to ask a question. Am I right?

every gear ratio has a use. 5:3 ratio (i hope were talking on the same page, 5 is on the motor and the 3 is on the wheel) if your robot is light enough, then yes, that will be a very good ratio to use. If your robot is a 18x18x18 metal cube, better stick to a 1:1 ratio.
It isn’t super helpful for drive aside from providing a list of gear ratios but this may help you out with figuring out gear ratios for arms and such. The preferred torque is the most efficient and you may notice that it is 1/2 of stall torque (1/2 of 6.5 inch pounds which also works out to be about 1/2 of the no load speed (1/2 of 100rpm) of the vex motors.

there cant be an ideal gear ratio for a motor brand because as most will tell you you can buy the same motor 3 time from the same maunfaturer and the rpm/torque/effiency will be different all 3 times.
Then that is a very unreliable manufacturer. Sure, there is a margain of error, but the difference isn’t very signifigant.
From personal experience, the margin of error is around 5% or more in either direction, faster or slower. Personally, on most systems it doesn’t make a huge difference but on the drivetrain it does make a difference between the bot listing as it moves and driving in a nearly straight line.
Personally I would not recommend this gear ratio. Overheating motors on *decently * heavy robots with this gear ratio are very common during competition. I have an Omni drive geared 5:3 sitting on my desk now for testing purposes. Even without a load the four motors do get mildly warm. From experience I’d prefer doing a direct motor drive or use sprockets/other gears for less strenuous gear ratios.

Not enough information:
What size wheels?
What weight robot?
X or plus style holo?
i got the top position last year, gear 33 are the most popular competition in our town and also in our schools,it is just awsome
