Re: Kitbots after Week 1
We used the AM14U chassis and are happy with it.
Our chassis includes several "upgrades" -- 28"W x 27.5"L with 8.76" and 12.6" wheelbases, belly pans, four 4" performance wheels with nitrile tread on short wheelbase, two 4" dual omniwheels on long wheelbase, three CIM single speed gearboxes (7.86:1), #35 chain drive with simple deflection tensioners, pontoon cover/stiffeners that support intake arm clevises. There are pictures of our chassis posted previously.
We also built a one-piece bumper with corners reinforced by aluminum angle inside, with backing pocketed to clear minor protrusions and to enable a tight fit between wood and metal. We think this really helped limit impact stresses.
TL;DR: the 2014 kit chassis is a good starting point. It just needs to be fed some steroids, as Karthik would say.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
