Re: Weight Concerns
I've posted before on this. Take a piece of 1/4" Birch or Oak plywood, some 6oz. s-2 fiberglass cloth and some laminating epoxy. Put one layer of fiberglass on each side. The strength is amazing. Cost - 4'x4'x1/4" 24$, 1 qt. epoxy 18$. 2 yard x 60" S-2 6oz. cloth 16$ per yard. Put some fiber in your robot's diet and you'll loose weight.
