i mean i think it’s fair to consider it a pretty big assumption you made based off one person if that’s what this whole thread is abt. idk a single person who’s called mecs bumpy before and i dont see any reason why they would be lol
In a perfect world, these mecanums would not be bumpy at all. (You said it yourself, the orthographic projection looks perfectly round.)
However, when driving, there will always be a bit of slop on the mecanum wheels, and at some points they are supported by a roller contacting the ground far to one side of the wheel. This means that the wheel will always wobble slightly.
So that’s why people think mecanum wheels are bumpy. It doesn’t have to do with 44’s wheels, just that most implementations of mecanums really are bumpier than omnis.
