Why do we usually create a robot to look like a human? Practical design for robots would suit the work they perform. A robot doesn’t need a face to function. Arms, legs, hands, a head, etc. how much of that design is practical and functional to suit the robot’s purpose?
So why give them the look of people? Does it make them seem more a part of our world, less intimidating or sterile? We have machines which don’t look human.
