What a fascinating intersection of technology and human psychology!

"One thing I noticed toward the end is that, even though the robot remained expressive, it started feeling less alive. Early on, its motions surprised me: I had to interpret them, infer intent. But as I internalized how it worked, the prediction error faded Expressiveness is about communicating internal state. But perceived aliveness depends on something else: unpredictability, a certain opacity. This makes sense: living systems track a messy, high-dimensional world. Shoggoth Mini doesn’t.

This raises a question: do we actually want to build robots that feel alive? Or is there a threshold, somewhere past expressiveness, where the system becomes too agentic, too unpredictable to stay comfortable around humans?"

"ah, you hesitated" no more so than on every single other question.

the delay for the GPT to process a response is very unnerving. I find it worse than when the news is interviewing a remote site with a delay between responses. maybe if the eyes had LEDs to indicate activity rather than it just sitting there??? waiting for a GPT to do its thing is always going to force a delay especially when pushing the request to the cloud for a response.

also, "GPT-4o continuously listens to speech through the audio stream," is going to be problematic

This is adorable! I did some research on tentacle robots last year. The official term is “continuum robots” and there’s actually a great deal of research into their development due to their usefulness in medical robotics. This lecture is a great overview for the curious: https://youtu.be/4ktr10H04ak

This is so sick. I agree that it’s a little lame that we have all these AI capabilities right now, robotics improving, and all we can think of making is humanoid robots. Like I want a spider/squid hybrid robot running around my house

I've seen enough media from Japan to know where this is heading

Hell no! I seen this movie and I don't want any face-hugger sitting on my desk.

I e been wanting to do this with a basic stuffed animal now for a while.

Just basic interactions with a child plus lessons and a voice would be game changing for the toy world.

Beautiful work! I appreciate how this robot clearly does NOT try to look like any natural creature. I don't want a future where we can't easily distinguish nature from robotics. So far humanoid robots look clearly robotic too: hope that trend continues.

A Lovecraft reference, nice. I'm wondering whether a smaller model would suffice as well.

This is so cool! I love the idea of adding expressivity to non verbal, non human entities.

Great video of SpiRobs, the inspiration: https://www.youtube.com/watch?v=2GFyFmMm9-A

I seem to remember that the SpiRobs paper behind the (extremely neat) tentacle mechanism indicated that they were going for a patent.

I feel obliged to link to my favorite (but Very Unwise) maker project I have ever seen:

Get 4, Doc Oc

Also was thinking of Oogie Boogie Tim Burton

That's exactly what we want, a lamp that's just as annoying as an orange cat. /s

oh no I just saw a future where LLMs are the new wifi and touchscreens in appliances, we're going to let my refrigerator cry aren't we

Optimus robots can do anything without actually indians?
