Is there a Mecanum whitepaper available?

Direct drive toughbox nanos and 8" AM mecanums mix well... My only suggestion is to add a control in the drive code to reduce the speed range, as this configuration runs on the fast side.

Take that a step further - direct drive nanotube + mecanum wheels = 30 minute drivebase.

nanotube would work, but it's cheaper and stronger to build your own chassis.
we use direct drive 8" off of toughbox nanos, we HATE having to constantly adjust the tension. it's also lighter, and the gearboxes are also part of our chassis.
we recently installed a set of new rollers, and found that the rollers contact each other. we think that they just need to be broken in.

I noticed that there is a couple different roller types available for the mecanum wheels. One is gray and the other is like a black rubber. Which would be better for driving on the slippery bridge? Can these be mixed (alternated) to use both types on each wheel?

Also can these rollers be roughed up with sand paper for better traction on the bridge or are there any other tricks for improving bridge traction with the mecanum wheels like adding weight directly over them?

Any tips are appreciated...

Thanks
