Re: Mecanum problems

I take it by "shaking" you mean that you are having a pretty bumpy ride.

Us too. We are modifying some of our electronic mounts to handle an increase in vibration.

If you look at the side view of the wheel you will see that it is not perfectly circular. While a "perfect" omni wheel is perfectly circular (or pretty darn close) that involves careful machining of the rollers.

AndyMark's solution, which is fine by me, was to get "close enough" by using the narrow rollers and wide rollers.... but the "close enough" shows up as vibration.

I am wondering if, as the rollers wear down a bit, they might approach closer to perfect roundness.

Watch the backlash on your BB trannies, if that is what you are using. If it starts to increase then you need to pay close attention to the thread on Banebots 56mm tranny problems.
