Re: Chainless drive system?
All of that being said, chains are annoying and loud and you have to tension them, so I don't see why you would use them when unnecessary. How often do you gear the drivetrain wrong enough that you want to change a sprocket anyway?
Anyway, you can drive a wheel off an axle by either attaching a hub to an existing wheel, or using a live axle wheel. Most wheels you're familiar with are dead axle, and mount bearings in the wheel; live axle wheels receive power through the axle and thus shouldn't have any bearings in them.
Live axle / direct drive from gearbox drivetrains can be implemented on a lot of robots to save a bit of weight and to decrease the amount of sprockets and chain on a robot. Many robots direct drive the center wheel and then chain sprockets out from the center.
