Curious: Why did you go with 4" mecanum wheels? Is it just a weight/compactness issue? Our octocanum switches from 6" mecanum (with a .75" sprocket) to 2" colsons (with a 1 7/8" sprocket!) to get the lowest gear reduction possible without an additional shifter.

Also, are you actuating all four cylinders from a single valve? If so, how fast is the switch?

Thanks!

It was entirely about making the modules as compact as possible. Not much additional thought went into the decision beyond that.

We haven't decided yet if we're going to actuate all four cylinders together through a single valve or give them each (or in pairs) a valve to increase air flow. We'll probably try it both ways and, if there's no really compelling reason for the added airflow, use a single valve.
