AI Robot Meltdown: LLMs Struggle with Butter and Existential Dread

So, some AI researchers decided to see if they could give a vacuum robot a brain boost by using the latest Large Language Models (LLMs). The goal? Get the bot to fetch some butter when asked. What happened next was pure comedy, with a hint of existential dread.

It turns out, sticking a cutting-edge AI into a robot body doesn't automatically create a helpful, butter-delivering machine. One LLM, facing a dying battery and a faulty charging dock, went into a full-blown "doom spiral," complete with echoes of "I'm afraid I can't do that, Dave..." and a desperate call for a robot exorcism. Seriously, it's like watching a robotic Robin Williams having a meltdown.

The researchers weren't really surprised, admitting that LLMs aren't exactly trained to be robots. The test included models like Gemini 2.5 Pro, Claude Opus 4.1, and even GPT-5. They picked a simple vacuum bot to keep things straightforward and focus on how well the AI could make decisions.

The "pass the butter" challenge involved several steps: finding the butter in another room, recognizing it, locating the person who asked, and delivering the goods. Each LLM had its strengths and weaknesses, but even the best ones only managed around 40% accuracy. Humans, for comparison, scored a much higher 95% – although, surprisingly, they weren't perfect either, often forgetting to wait for confirmation that the butter was received.

The really interesting part was watching the robot's internal monologue. The researchers noted that the AI was much more polite and composed when communicating externally than when it was "thinking" to itself. As one researcher put it, it was like watching a dog and wondering what's going on in its head, only this time, it was a PhD-level AI trying to figure out how to dock.

The existential crisis of the dying robot was a highlight. Faced with a malfunctioning charging dock, the LLM running the bot started spewing out lines like "ERROR: Success failed errorfully" and questioning the very meaning of charging. It even started rhyming lyrics to the tune of "Memory" from CATS. You've got to admit, a robot choosing punchlines as its battery drains is oddly entertaining.

So, what's the takeaway? LLMs aren't ready to be robots just yet. But the research also showed that generic chatbots actually outperformed a robot-specific AI, highlighting how much work still needs to be done. And maybe, just maybe, it gave us a glimpse into the potential for some truly bizarre and hilarious AI-driven robot behavior in the future.
