Just a guess, but I am willing to bet it wasnt intended to be like that (if it truely is more than just an optical illusion). My guess is that their tensioning devices have a tendancy to pull the sprocket side of the axle closer to the gearbox (in essence making it look like the wheel is pointing inward) I would guess it is partially due to the way they canteliver the wheels out, but also the way the chain is wrapped on the inside sprocket and how the wheel is moved on slotted mounts to tension it)

When I took a "close" look at 254's robot, I did not notice it at all. I would be willing to bet it was not intentional if it was anything more than an optical illusion...

254/60 care to enlighten us?
