Re: How Do You Make Your Robot?
We generally use Bosch-Rexroth aluminum extrusion (very similar to 8020). We use the 20mm cross section profile for just about everything, but we have been known to use 30mm where we need the added strength.
We bolt (or rivet) everything - we seldom use welding if we can help it, since we don't have the equipment at our main shop.
