    I once had a robotics professor who argued any definition of 'robot' broad enough to include roombas and self-driving cars and industrial robot arms (even if made narrow enough to exclude remote-control toy cars, cars with cruise control, CNC mills and washing machines) would inevitably define cruise missiles as robots. Meaning the world had 'killer robots' before we had digital computers.

    Instead, he argued the definition of a robot is "I know it when I see it"

      What's wrong with a cruise missle being defined as a robot? It is one.

      Also I'd argue that a CNC machine is a robot as well, no different than a programmable industrial robotic arm.

      IMHO, a dishwasher isn't a robot because it is neither versatile in its objective, nor programmable.

        It's true - a robot arm is not so different from a CNC machine.

        But a 5-axis CNC is not so different from a 3-axis CNC, a 3-axis CNC is not so different from a laser cutter, a laser cutter is not so different from a vinyl cutter, a vinyl cutter is not so different from a large-format printer, and a large-format printer is no so different from an inkjet printer.

          I used to write printer drivers. I jet printers are tiny evil robots and I’ve been saying so for years.

        • tourmalinetaco 5 hours ago ago

          Yep, all robots, man. A robot requires these pre-requisites: reprogrammability and physical labor. The term “robot” comes from the Czechian “robota”, which means forced labor, and reprogrammability comes from industrial technology, where a mechanical/robot arm and other such devices need to be reprogrammable.

          MW also posits that a “humanoid or animalistic” design makes a robot, but that’s objectively wrong, because that’s androids.

          Cars with computers are robots, CNC machines (including vinyl cutters and inkjets) are robots, even a box fan can be if you hook it into an IC and give it commands, or in the case of s dishwasher you find a way to replace its firmware or just replace the internals with your own.

        • fragmede a day ago ago

          What if you define robot as anything with an arm that can do arbitrary things?

          • OrderlyTiamat a day ago ago

            This doesn't include a roomba.

            In general the game of necessary and sufficient conditions for any non mathematical concept will always lead to inconsistencies, there's no such prescriptive "definition" for most words. try defining "game", or "chair" in such a way!

        • bitwize a day ago ago

          When I was a kid my dad had an HP-7475A pen plotter. When explaining this device to friends today, I describe it as "a robot that draws with a pen". It's got a little robot hand and everything that can pick up and replace one of six pens.

        > neither versatile in its objective, nor programmable.

        how programmable does it have to be for the robotic classification to stick? A cruise missile also cannot be programmed to be general - you can only program it to follow a trajectory. Just like you can only program a dishwasher to do dishes in a particular way.

        • detourdog 2 days ago ago

          Autonetics designed the inertial guidance system for the Minuteman 1 ICBM. They also sold it as a general purpose computer and distributed to Universities to learn about general purpose computers.

          It took realtime input from gyroscopes and starmaps and calculated output for the thrusters.

          No? You’re thinking of a rocket-motored missile. Cruise missiles are little planes. They can often autonomously navigate terrain. A cruise missile is more a robot than a dishwasher, even a smart one, particularly modern ones which do target identification onboard.

          • chii a day ago ago

            but it is still cruise missilin' and not dishwashing.

            Therefore, i am just arguing that classifying cruise missiles as robots, but failing to make the same judgement on a dishwasher is biased thinking.

            • JumpCrisscross a day ago ago

              > classifying cruise missiles as robots, but failing to make the same judgement on a dishwasher is biased thinking

              'Cruise missile' and 'diswasher' are about as broad categories as robot versus not robot. (If you're calling out 'biased thinking,' say why it is. Otherwise it sound slick you don't know what bias means.)

              • chii a day ago ago

                > about as broad categories as robot versus not robot.

                there's no way cruise missiles and dishwashers as categories are similar in broadness to the categories of "robot" vs "not robot".

                The point i was trying to make is an attempt to tease out the bias in the original post i am replying to - that of having the robot moniker assigned to things they fear more, instead of a more objective classification.

                  > that of having the robot moniker assigned to things they fear more, instead of a more objective classification

                  Sure. I’m rejecting that oversimplification.

                  Solving a Sinner circle is fundamentally simpler than even a basic flight-control system. The examples you chose refuse your comparison. That suggests your model is wrong.

        • cowlevel 2 days ago ago

          Most robots are programmed to do one thing well. You could program a cruise missile to fly around in circles or chase the sun, just like you could program an industrial robot arm to wave like a music conductor, but they don't because that doesn't match the goals of their users.

          • JumpCrisscross a day ago ago

            They absolutely do for research and target practice.

        I think the distinction is about the interaction with physical world. I robot must change its own position and/or can be able to manipulate other objects.

        A washing machine does’t care about the pose of the laundry inside. No direct manipulation. It just rotates the drum with a motor.

        A self driving car locates and moves itself. A robotic arm manipulates objects. They are like half-robots. A “robot” robot can do both.

        • theoreticalmal 2 days ago ago

          My washing machine detects when the wet laundry inside is imbalanced and will do a slow half rotation to evenly spaced the wet laundry before a spin cycle

          • fuzzfactor 2 days ago ago

            You've got a more intelligent washer than me.

            But actually my washer does respond to to load levels that it senses, then fills with different amounts of water accordingly.

            And then like an unruly robot, it sometimes becomes unbalanced and "ambles" across the floor unexpectedly when it's supposed to be a completely stationary automaton.

    • ostacke 2 days ago ago

      A cruise missile being a robot is not far-fetched, I’d say. In Swedish both cruise and ballistic missiles (and other similar munitions) are called robots within the military.

    • ktallett 2 days ago ago

      Roombas, self driving cars, industrial robot arms (depending on what they do), cruise control,cruise missiles, are all robots by the dictionary definition. They react to their environment. That's the classifier.

      His view of I know it when I see it is nuts but he is right on many of the classifications. Some were incorrect though. But a robot is just anything that has a sensor to interact with the environment.

      We have simply changed the meaning to be more human like which is not accurate.

      • michaelt 2 days ago ago

        > They react to their environment. That's the classifier.

        An industrial robot arm, out of the box, only has internal sensing (joint position, torque etc) and a start/stop button - can't sense the external environment at all.

        But I've got a light on my porch that turns on when it gets dark.

        By the 'react to the environment' definition the former is not a robot, and the latter is.

        • fatherzine 2 days ago ago

          The distinction between internal and external variables is interesting in its own right, but both devices are technically robots. A thermostat is also a robot.

          We're starting to need gradual words to linguistically orient ourselves: automaton, drone, robot, android, etc. Where "robot" is a narrowing of the technical "feedback loop device".

        • ktallett 2 days ago ago

          It would have to have a force torque sensor which interacts with the environment around it (aka the object being manipulated). Hence it being a robot arm.

          However if indeed an industrial arm doesn't have that, then yes robot is the wrong term for it.

    • TomGarden 2 days ago ago

      "I know it when I see it" has to be up there in terms of useless thought-terminating clichés together with "no smoke without fire" and "if he wanted to he would"

      • kgwgk 2 days ago ago

        For those unaware, this was famously stated as a test for hardcore pornography by a Supreme Court of the US justice in 1964.

        • TomGarden 2 days ago ago

          Yeah. It's really bothersome.

          I think the modern day equivalent is the constant huffing and puffing around where to draw the line for tech legislation, with the implicit message that 'if a line is hard to draw, we should not draw it' and a constant bad-faith battle for perfectly defined legislation.

          The answer to 'where do we draw the line for this thing that has widespread negative effects' is always "somewhere".

      • nkrisc 2 days ago ago

        The point is that there is no objective measure one can use and the definition at any given time is dependent on the cultural and societal context.

        Something that might have been considered pornography 100 years ago might be considered tame today.

        • roenxi 2 days ago ago

          It goes a bit further than that. If there isn't a somewhat objective definition then you can't ever be sure that two people are talking about the same thing. Sharing the same context isn't enough to reliably get a convergence of beliefs about whether something falls into a category. And it is a mistake to start legislating about it because the laws are going to be meaningless.

        • TomGarden 2 days ago ago

          What I mean is that throwing up your hands and saying 'I know it when I see it' is entirely pointless. There's a reason scientific papers have an (often long) section for definitions.

          • danaris 2 days ago ago

            It's not pointless.

            It's acknowledging that this is a place where rigid, universal definitions, that include everything that is X and exclude everything that is not X, are not possible. That human judgement is necessary to determine what is or isn't X.

            This doesn't mean that we have no guidelines whatsoever for how to recognize X. We can list qualities that a robot either must have, or should probably have, and anything that definitely doesn't have them probably isn't a robot, and anything that has enough of them probably is a robot.

            • TomGarden 2 days ago ago

              I just don't think we'll be able to agree (and that's okay). I'll just put my thoughts here, not expecting that you'll meet me anywhere.

              Human judgement in itself is not uniform or defined enough for it to be useful, but dispersed and more random than just situational. And yes, universal definitions in general are extremely rare outside of a subset of definitions in hard sciences. The only reasonable thing we can do is agree on a definition in a certain context, ie definitions in a scientific paper or in a conversation. But 'I know it when I see it' or some vague idea of human judgement doesn't even work as a definition within a defined context, and therefore doesn't help us find common ground or make a conversation useful. Which is why I characterize it as a thought-terminating cliché.

              In a way, this entire back-and-forth is an example of us 'knowing what a thought-terminating cliché is when we see it' which unsurprisingly, to me, is unhelpful.

              • amanaplanacanal 2 days ago ago

                Common speech is slippery, definitions change over time, and the only way we can define words is to see how people use them. In technical context we do define words so that everybody knows what we are talking about.

                A good example is the use of the term AI, and how we use it in CS vs how the general public understand it.

              • danaris 2 days ago ago

                I think there's a meaningful difference there: "thought-terminating cliché" specifically means something that causes those who say it (or accept it) to stop thinking there. That's not just something that's up to interpretation: that's something that has actual variation depending on the people involved.

                To put it another way, if we posit Person A and Person B, they might both describe "I'll know it when I see it" as a thought-terminating cliché, because they've heard it described as such, and Person A will actually leave it at that, not seeing any reason to discuss the subject further. But Person B does want to continue discussing, and certainly continues thinking about it. Thus, even though they saw the phrase as a thought-terminating cliché, for them, it actually wasn't one.

                On the other hand, terms like "robot" and "pornography" really are purely something that's up to interpretation. If I say "I think a light with a motion detector is not a robot", there's no more objective meaning of "robot" that anyone can point to to definitively say I'm wrong.

              A Supreme Court judge being reluctant to define a social norm makes sense to me. Other future judges have the ability to update their perception. Prescribing social norms to a textual definition is a problem as social norms change.

  • mauvehaus 2 days ago ago

    A food processor and stand mixer are robots in French[0]. I suppose this rather supports the claim that "robot" is a social construct as different societies have constructed it differently. N.b. I haven't taken a French class in almost 30 years. Please excuse any nuances in the French use of "robot" in this context that I may have missed.

    ETA: I almost forgot! Our nearby hardware store has a robot that sharpens kitchen knives. It's much less impressive than that sounds, both in appearance and how well it actually sharpens a knife. Nevertheless, I did note to the person operating it that if the robot uprising comes, we may regret the choice to simply give the robots knives.

    One time I was messing around with the settings for a 3D printer in whatever software I was using to control it, and found a dropdown for "Machine type" or similar that defined my printer as a "3-axis robot." That gave me pause. Is it a robot? Maybe. That printer didn't even have any sensors, apart from the thermistors that fed into the temperature control PID loops. But by someone's definition, it's a robot.

    That was and remains fun to think about. I guess that like the author, I will "be pedantic all day long."

    There's an old saying, "if it works it's not AI". We could make a similar statement: "if it works, it's not robotics". That is, once a robot becomes reliable and efficient enough for everyday use, we no longer consider it a robot we just consider it a machine or tool.

  • bitwize a day ago ago

    Indeed. "Robot" is a radial category that includes machines that resemble humans in either appearance or the sophistication of tasks they can perform. It's one if those terms like "fruit" that doesn't have a strict technical definition. A robotic arm is described as robotic because of its resemblance to a human arm. If you put human-like limbs on, say, a tank (as in Metal Gear, or Tomy's Battle Skipper line of toys from the 90s), the tank becomes more "robotic" as a result. A self-driving truck is considered a robot because its operation incorporates planning, navigation, following of rules including traffic laws, and responding to stimuli such as traffic and people/animals in the road, all undertaken autonomously and resembling the kinds of decisions a human must make when driving a vehicle.

    Oh! TFA is written by Mikell Taylor. I worked with her once, yonks ago.

  • TacticalCoder 2 days ago ago

    Roomba and the likes are definitely robots. The advanced ones have cameras, map your floor, vaccuum clean, water clean, etc. You can contact them remotely (a friend uses her cleaning robot to spy on her husband while he's at home!) and give them orders.

    Nobody ever said "robot" meant "machines with AGI thinking": robot, literally as defined by the person mentioned in TFA and who coined the term, meant "to work" / "forced labor". Work/labor that could be done by servants.

    If cleaning my entire apartment by vaccuum cleaning, water cleaning, giving me reports about it, obeying my orders (e.g. if I tell to stop) ain't "automated labor that could have been done by a servant", I don't know what is.
