Re: Mechanum drive-strafing issue

We use 2.5" CIM motors and CIMple boxes for transmissions. (one CIM per transmission)

Any other teams that use mechanum drive, please respond and tell me which motors and transmissions are being used.

P.S. I am new to the forum, so please be forgiving.
Are you using the CIMple boxes directly attached to the wheels, or do you have a reduction between the gearboxes and wheels? A CIMple box directly attached to a wheel will not have enough torque to turn the wheels. You need some other sort of reduction. Also what size wheels?
