Alright, I'm building the robot project I was putting off. This is so fucking cool.

Excellent work!

rtc handling 300ms+ delay and still pulling off tasks like plugging ethernet is kinda nuts. what i'm not getting is but how's it keeping the control loop stable without retraining? some sort of latent plan caching?

It uses an inpainting algorithm (adapted from image generation literature) to produce future actions that are consistent with the current trajectory. It's sort of like warm-starting from a cached plan, although the plan isn't latent, it's directly in action space. Hopefully that answers your question -- there are many more details in the blog post and paper :)

I love the implications of a robot that can plug in Ethernet cables.

Just need one that can plug in USB-A cables the first attempt (I average 3 attempts).
