That's exactly what it is

The torque that the driving motor puts on the bevel gears is small if you do a 1st stage bevel gear reduction. Couple that with good bearings and friction and that might be enough.

That's what I've been thinking I might resort to.

You could also use 2 sets of counter-rotating bevels in the caster box (lower part of the module), although that would be harder to set up mechanically.

I think I understand this but could you elaborate on how it would work? Like two side-by-side shafts going into the lower part of the module to drive the wheel? I've been thinking about that but haven't worked out how it would work

What kind of loads/what size motor are we looking at here? The slip ring solution isn't half bad if this is for something like a motorized suitcase.

Two of these would have to support the weight of a ~250lb machine. The reason I'd like to do it this way is so that I can power both wheels from one motor that's larger than reasonable to put in the rotating module. Thank you for your suggestions!
