I'm not saying anything about the design work, it's just the ball wheel concept has been worked many different ways and has never shown anything working. At best, they can trick some simulators but never seem to function.
 
You should have watched the video to the end and seen why it works. Maybe Helloa can do a design of the one in the video?
Yes, an animation! that might be something a bit tough to do though.

Well I can tell you that friction is your enemy on what your video had show for that has been tried before as well. I don't have any ball wheels in the works now days but I still have a liking of them. Maybe it is the same as just fond memories. Sometimes I do go back and look at old designs and put my experience to them and since Helloha is doing this I think I will make a few changes to see if I can get a little more out of it.  ;) 3.0

Yes, friction is always a problem, but think of a ball wheel using 4 inch diameter steel balls and how tiny the friction would appear.

based on a previous wheel model, modified the "3 by 3 arms" to "6 by 6"

orange sphere/ball indicates the weight/mass is low

simple testing for the add-on VIII, implementing magnets (using wind force to act as magnet) to the test, giving an extra push

trying my hands on wm2d, testing out magnet effect-like simulation, II
 
 using electrostatics to act as magnet
 
 go to "world",
 choose "force field",
 under sample force choose "electrostatics",
 inside the Fx label, "8.99e9" indicates repel, give a negative sign "-8.99e9" attract,
 for body with material "steel" will have the effect,
 for body with material "wood" will not have the effect,
 (under the body properties, either choose the 'material' or change the value of the 'charge')
 
 or very simple,
 
 go to "world",
 choose "electrostatics",
 check it on,
 "8.99e9" indicates repel, give a negative sign "-8.99e9" attract
