Re: pic: Octocanum Concept V2
The traction wheel does not need to lift up that far. If you flip the traction and mecanum wheels around you could easily get away with a .25in liftoff distance (also, as previously stated, you get a longer wheelbase when you need it most). It will probably also be easier to pull the end of the traction wheel down instead of the module horizontally. You're also likely on the traction wheel for a very short time so you could easily get away with a much smaller wheel (like 2.5 inches or less in diameter). That versablock is also getting cantilevered pretty far, I'd watch out for that. Hex bearings are infamous for breaking under those kinds of conditions (but have also been improved since I last heard that was a problem).
