What type/shape of metal ( i.e. tubular aluminum) should I use for a robot frame? Answered
I am building a robot. It will be about 1.5 meters long, about 30 centimeters high, about 40 centimeters wide ( all dimensions excluding wheels, tracks, etc.). It's body will be a metal frame with an outer fiberglass shell. The frame needs to be strong, lightweight, and rugged. It would also be nice if the frame could be welded with a homade stick welder, but that isn't a primary concern. Any advice is appreciated. Thanks!
