No we didn't decide to do this, it wasn't even really considered b/c it wouldn't have worked with our design.
But I would like to know what kind of rubber those "rubber tubes" are, both Akash's and the Disco-bot's.
We
are going to have an intake roller, and slipping a rubber tube over it for traction sounds like a really elegant solution (as opposed to wraping neoprene whether stripping around it
)
