188 made that mistake in 2006. We built a very fancy laser-cut and welded aluminum sheetmetal chassis, with a low profile and clearance for climbing ramps. It was exceptionally light, and quite stiff in most directions when the top plate was bolted on (to tie the gearboxes and bottom plate together).
Then we stuck a 30-pound shooter on the top, along with enough other stuff that the robot was at the weight limit, as usual.
