A CNC machine is as much a robot as an industrial arm is. I suspect you might specifically mean "autonomous robot"?

  is anything with a motor a robot? of course there is a hierarchy, with the stepper-driven open-loop machine he gave as an example being further down the ladder.

    No, I mean literally. Industrial arms aren't necessarily any more complex than CNC machines. They may not have any more motors. They perform tasks of similar complexity, with similar programming models. We call them "robot arms" quite happily.

      this is inaccurate in a variety of dimensions. they have more complicated gearing (strain-wave) and and perception systems for safety (for nearby humans) and positioning (unless you can get the stunning tolerance stacking that the automotive industry gets.)
