Re: Chain driven vs Direct drive mechanum

Tom Line is right on the money for a development robot.

If i knew the gearing I wanted for a competition 'bot I'd go with direct drive (if at all practical) just to not have to deal with chains, designing tensioning systems, and the keys/set-screws generally associated with sprockets. We used a chain-driven mecanum driveline this year, it was not hassle-free.
