Yeah, really like that project. The main difference is that it's much shorter than ours, and shorter robots are cheaper. The downside is that it can't really reach normal human spaces. Actually, we made another robot called Zeroth Bot which you can build for $350 if you want: https://docs.kscale.dev/docs/zeroth-01

We are planning to release a similar-size robot later this year (calling it M-Bot) that will be closer in height and price, but our current focus has been on launching the full-size humanoid.

Mechanically, I think Berkeley Humanoid Lite is pretty similar to the 3D printed one we made last year. Our main focus with the K-Bot redesign was to make it not break so much. 3D printed components break a lot and repair time can be quite long. Also, having the wiring routed internally makes a huge, huge difference. So there are some benefits to doing QA on a manufacturing line in terms of quality and consistency.

How far away from robot hands/manipulators that are dexterous enough to repair other robots?

That is a good question. I think mechanically we're probably there today, but on the intelligence level, who knows... If I had to guess, probably 1-3 years

obviously there's more to the kinematics than making the legs longer, but can't they just make the legs longer for it to be taller?

Longer legs means more inertia on the actuators, which means bigger actuators + bigger battery, which means heavier robot, which means...

right? thanks!
