Our last three chassis have been:
2014 -- souped-up 6WD kitbot
2015 -- semi-custom 6WD-plus-drop-strafe using VexPro clamp-on-tube gearboxes (see Sam's plug earlier)
2016 -- souped-up Rhino track drive
We like starting with stuff that others have developed, and tweaking it to suit our game play priorities.
As Dave said
long ago, steal from the best, then invent the rest.

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.
