Like I said before it designed to fill the bulldozer role on the field. Those are the 2x4x1/8 tubes like we got in the kit last year, and the outside plates are 3/16. there will be standoffs as part of the track system, but I didn't add them in yet. both the 2x4's and the outside plates will likely end up full of holes in the final robot (If it turns out that we can even use this design next year), then we will just Epoxy a piece of 1/16 lexan over the holes on the outside plates to keep stuff from getting caught in them (bad experience in atlanta with stuff catching in holes).
If we end up building this we will deside where mechanisms need to be mounted before drilling any lightening holes to make it easy to mount stuff.
By the way the bottom plate is only 1/16, just to help keep the frame square and mount stuff like the battery and electronics to.
