Yes they don't need chains or sprockets, but they are still larger and very heavy. The larger diameter the wheel, the more force you need to excelerate regardless. Add weight and the required force goes up even further.

Yes maybe claiming that someone could push a mecanum with a finger was a exaggerated. Frankly I might just be spoiled by robots that can't be pushed at all.
I'm not trying to say whether they are better or not or when they should be used, I'm just tiered of the assumptions and rumors that are tossed around.

You say they need more practice but you have never driven one. You say they are very heavy but totally discount the weight and extra complexity you need for six wheel drive.

I just want everyone to know that when you state facts you better be sure of them.
