Mecanum Wheel to Axle assemble

FTC robotics Team 12896 would like some help assembling a chassis using Mecanum wheels. We recently purchases 100mm (~4") mecanum wheels (part #RB-Nex-13) and 6mm bore Pololu universal mounting hubs (part #RB-Pol-136) from the robot shop, however, when the parts arrived, it was clear the the hubs could not be attached to the wheels. Therefore, it was not possible to assemble the chassis using either direct connection to the 6mm motor shaft or a 6mm axle. There must be additional parts that are needed. We could attempt to fabricate an adapter plate that would provide the connection, but some parts specifically designed for this application would be better.

Would someone please tells us what additional parts may be needed. A general description of the assembly would also be appreciated.

Thanks,

Hi,

The correct adapter would be the RB-Nex-17 for those wheels and a 6mm motor shaft.
