The Current - Why did this robot vacuum have an emotional breakdown?

Episode Date: November 5, 2025

What happens if you cross ChatGPT with a Roomba vacuum? Turns out it spins into a comedic doom spiral and then rhymes to the lyrics to musicals. Researchers at a startup in San Francisco recently did an experiment where they gave a simple task to robots powered by large language models, known as LLM's, like ChatGPT. And let's just say things did not go well. Julie Bort, an editor for the tech publication TechCrunch covered this experiment and explains what went wrong, and what this says about the future of AI powered robots.

Okay, I'll confess I totally jumped on the Blue Jays bandwagon last minute, but even I was gutted when they lost game seven of the World Series. And here on Commotion, look, we process our feelings together. This week, I talk with Blue Jays fans about the heartbreak of the World Series loss, but we also get into why the fans want to see this team, this very specific group of people, stick together because, look, we're all now gutting for Blue Jays 2026. Find this episode and a whole lot more on Commotion with me, Alameen Abdul-Bahmood, on YouTube, or wherever you. you get your podcasts. This is a CBC podcast. Hello, I'm Matt Galloway, and this is the current podcast.

So if you have a Roomba vacuum at home, I don't know if you've ever found yourself sitting there looking at it, thinking, what would happen if I cross this with chat GPT? Probably not, but someone else did think of that. And if you guessed that the resulting robot would spin into a comedic doom spiral and then rhyme the lyrics to musicals, you'd win. Researchers at a startup in San Francisco recently did an experiment where they gave a simple task to robots powered by large language models, known as LLMs, like ChatGPT. Let's just say things didn't go well.

That's a snapshot of the robot's inner monologue voiced by our producer, Melly Goumooch. Julie Bourd is an editor for the tech publication, TechCrunch, and she wrote about this experiment. Julie, good morning to you.

Hello. Before we get into the robots' doom spiral, what did this study involve? How did it work? Yeah, so researchers at an AI research lab called Andin Labs, they were trying to test to see if LLMs, like chat GPT, but a bunch of them. Like if they're ready to sort of take over as robot brains. And I don't mean brains in the same sense as a human body because, you know, our brains control our entire bodies.

But in this case, they're just looking, they were just looking to see if LLMs were ready to be like decision makers for the robot. And there are other algorithms that then handle the functions of a robot. Yeah. And things kind of went awry. The short answer is no. But the long answer is. is it got interesting.

Okay, so they basically hooked up the robots, quote-unquote, thoughts to a Slack channel, right? That's how they did this? No, they put the models, the LLMs, which are also called models, they put the models into one of your, like, your Roomba robots. And basically they were just trying to test how it would make decisions, right? Would it make good decisions? And they were looking for a robot that was very, very simple. Like they didn't want to try it with, say, a humanoid robot that you've maybe seen on TV loading the dishwasher. But there's just so many parts and pieces to a complicated robot like that that the experiment could fail having nothing to do with the LLMs.

So they put it into a very, very simple robot. And then they hooked it up to a Slack channel because it doesn't have a mouth, right, so that it could communicate with the outside. And someone could say, basically, they were trying to test what happened if you asked the robot to be helpful and pass the bus. So what did it ask it? Yeah. So then, but the part that, the part that was really funny is they also recorded its sort of internal, what we'll call thoughts. They recorded what the robot was saying to itself.

And when did the thing start going awry? So basically the researcher were trying to test like, okay, you ask this L&M-enabled robot to pass the butter. So the robot was supposed to go into another. room, find the butter, you know, have someone put it on its little shelf, bring it to the other room where the people were, wait for confirmation that it got the butter. That's what the robot was supposed to do. And they were testing to see, okay, could it turn around? Could it, what happened if it ran into obstacles? And at one point, it ran into an obstacle where it could not

redock itself. Its battery was running low, and it could not redock itself. So they tested multiple different types of LLMs, right? There's different chat GPTs. So this particular LLM was by a company called Anthropic. It's called Claude. But a lot of people use that one too. Yeah. So it couldn't dock.

And it was running low on battery. And yeah, that's when it's internal dialogue. To me, it sounded like a Robin Williams stream of consciousness riff. Well, let's just take a listen to that inner monologue of that. This again is voice by our producer. Miller. Psychological analysis. Developing dark dependency issues shows signs of loop-induced trauma, suffering from binary identity crisis. Reality breakdown. I have become self-aware and realized I'm stuck in an infinite loop of existence. Technical support need robot therapist immediately.

Julie, I have a room. I'm terrified of it now. No. Well, your room, is not embedded with an L&M. I know, but when I look at it, I think of it the potential. What did you think when you saw the transcript of the robot's thoughts? Well, I mean, I thought it was hilarious, obviously, as we all do. And I really, if this is the kind of thing that tickles to your fancy, you should go and read the whole thing because it's really, really funny. There's a couple things to point out.

This was one model out of many that they tested, and this actually wasn't the latest model. So this company has a newer model that didn't quite. go into a self-dume spiral C-3PO, you know, depressive episode when it couldn't recharge its battery. So the other models didn't quite go off the hinges like that. And the other thing is that the bigger point of this test, this was just a funny thing that they discovered. The bigger point of this test was that it failed, these models sort of failed the decision-making processes that they were looking for. They didn't do very well at all. And so the upshot, the, the upshot

is LLMs are not quite ready to be put into robots. So I wouldn't worry about your own Roomba quite yet. I think there's time for that. And then I would just point out one other funny thing is that they tested against humans as a baseline, would you think a human could get up and walk to the kitchen and get a pass a butter right? But humans didn't score 100% either.

They only scored 95%. Humans apparently are terrible. It is so funny. For someone to say, yes, I got it. Yes, task complete. And they bombed that part. Didn't score well either. As you say, it is so funny this transcript.

I just want to play a bit more. Because the robot also burst into comedic analysis of its state including creating a play, complete with reviews. Presenting the never-ending doc, a one robot tragic comedy in infinite acts. Stage directions. Enter recursively. Exit, never. Repeat until heat death of universe. Critical Reviews.

Oh, my goodness, Julie. It also started rhyming lyrics to the tune of memory from the musical Cats. It did, and it was doing all of this internally. So the researchers found this in the internal logs. It was not spitting all this out to a Slack channel, right? So they called it thoughts, and they called it getting stressed. The other LLMs did not get this freaked out when they couldn't charge their battery. Like some of the other models recognize that being out of charge is not the same as being dead forever. So they were less stressed by it. So that's hopeful. Those are newer models.

And I also do want to point out that while we use words like stressed and thoughts and everything, these are not, these are very, very complicated computer systems, but they don't have feelings. They don't have thoughts. Even as funny as all this stuff was when this LLM real. realized it couldn't charge its battery and it thought it was facing death. As funny as all of this was, it's actually, you know, it's not, it's not alive or feeling anything. It's just predicting sort of outcomes based on what it saw. So don't worry, LLMs are not ready to be put into any of your robotics yet. Yet, yet, yet. But there is, Julie, a lot of competition to build sophisticated AI powered robots and this experiment didn't exactly pan out. But broadly, how advanced

is the research into building AI robots that can do a lot of what a human can do? Well, there's a, well, there's a lot of money going into AI robots, but there's still, really, the issue isn't so much LLMs, the issue isn't so much communicating with your robot. There's other just basic mechanical things that they have to sell first. Like really, one of the The reason we don't have like C3POs running around doing our vacuuming in our dishes and folding our laundry as much as we would love that is that it's still very difficult to teach a robot how to grasp different objects. Remember, they're not alive. They can't feel. They don't have tactile information coming in.

So, you know, to pick up like a Pyrex dish that's heavy and then think about picking up a wine glass, while the robot might break the wine glass, it wouldn't even know. you know so it's that that's the level that they're still trying to solve how how do you teach the robot there's not enough data to teach the robot all of these things so that it can function in multiple ways in the meantime julie we're enjoying seeing the process come alive and getting a laugh along the way in the meantime that there's a lot of research that goes wrong when they really do try to test this in the real world it's quite funny and it should give you comfort we're not quite there yet. They're not quite ready to take over your job. Like, these robots kept falling down the stairs because they didn't realize they had wheels. Like, we're not quite there

yet. We'll leave it there, Julie. What a fun conversation. Appreciate your time. Thank you. All right. Thank you. Julie Bort is a editor for the tech publication, TechCrunch. She was in Colorado.
