pic: Its twins - prototype drives

[GeeTwo]

I like the wide open interior space - it would have relived a number of constraints on manipulators this year.

With those long chain runs close to the carpet, I would be worried about snagging threads and other debris, especially as the chains get loose. Is there some reason you decided to route the idler offsets to pull the top chain down rather than lift the bottom chain up?

My initial understanding of the small wheels inboard was to have the ability for more contact points with the floor. If you reduced this from 6 wheels per module to 4, would you make the wheels of equal/closer size, or did you do this for some other reason?
