Why the focus on humanoid robots? Even if factories and warehouses are replete with stairs, making wheels unsuitable, I'm not sure there's a need for a human shape. Why a head? Is that to make it friendlier or something to humans it might work alongside? An R-series astromech droid feels like it's built for industrial purposes (as a close second, the first thing R2 is built for is plot). This robot doesn't need to be a human to leverage human-like hands. So is there a purpose to the shape I'm missing?
