On an assembly line, a digital twin of a robot may look identical to the physical robot, especially if it is photo-realistically rendered. The digital twin can mimic the physical robot’s movement, for example. The digital twin may not pass a close inspection for similarity, however. It cannot have the internal minutiae and complexity nature routinely provides. A robot’s digital twin may lack fastener threads, weld details, etc. found on the physical robot.
