Re: Wheels for drivetrain

When you say the motors directly drive the wheels, do you mean there's no transmission in between? If so, I think you'll have trouble with a lack of torque, whether you stay with mecanums or change to any other type of wheel.

Also, a four wheel drive with high-traction wheels will have difficulty turning on carpet. I recommend using one pair of traction wheels (plaction, pneumatic, etc.) and one pair of slick wheels (eg. omni). Put the traction wheels in the back and slicks in the front, or the other way around. And if you don't have it already, I highly recommend some reduction between the motors and wheels; you'll need the torque.
