Omni-Wheel Design

[fightoplankton]

Has any team come up with an omni-wheel design that allows for the mini-wheels in each omni wheel to turn on their own?

Can you explain further what you mean by each of the mini-whells turning on their own. My team 1257 had a functional holonomic drive using the omni-wheels last year the mini-wheels spin on their own based on the movement of the robot. Please elaborate on your question and im sure i can help you out.
P.S i hope you dont have in mine an omni-whell design for this years competition i wouldnt recomend it

[fightoplankton]

sorry. what i mean is that the omnis are not positioned like this

or any similar designs. I want to know if you can get the mini-wheels moving by motor or some other means.

yea for the holonomic drive the wheels are position at 45 degree angles like this

/ \ I cant understand a practical reason for controling the miniwheels
\ / on a motor?

[fightoplankton]

there is...i can assure you

[Seekthematrix]

one, i dont think its possible, two the prograaming would be ridicoulously complex to make it all those wheels actually being controlled by motors.

[fightoplankton]

i figured it out...using gears

Sure its possible, but it would be overcomplicated, require very big wheels or very small gears.

The reasons I could see for this would be so be able to more easily climb the ramp, and have more pushing power in the forward direction.
I think you talking about positioning the wheels like this.

with the rollers opposite. Is this correct?

Also the programing for this would be no more complicated than the pro gaming for a normal omni drive. However I don't see the benefit of this over using a swerve drive because its more complicated to build and doesn't hold any advantages over a swerve.
