How much does this matter in practice vs 7DoF arm?
Another interesting option is Raspberry Pico * N + Tiny PC. For control and thinking. They can be connected via wifi or blutooth.
It's sort of open ended project. Having LLM with vision on mobile robot with arm.. has a lot of applications. AGX Orin 64GB is capable of running serious models.
A) bring down cost and expand the design space for the hardware and
B) minimise the barriers to working on the "software" problems where there still seem to be huge areas of mostly unaddressed challenges.
An open source platform seems like a good thing for both.
So factories are obvious but the real mass uptake is the home - and honestly I think something that cleans and tidies an hour a day might actually be achievable
Mass-produced (stamped / extruded / whatever) mechanical parts + hackable 'brains' is.
Robots do lend themselves well w/ respect to that last part. Worst case is rip out its control electronics wholesale & replace with your own motor drivers etc.
My potential concern is the "Apple" gatekeeping of parts.
Low volume, probably customized parts like R&D robotics tends to need? 3D printing is great, especially if the design files are available so you can modify the parts as required before printing. And then if you break something you can print another one off overnight instead of stalling your project for weeks waiting for new parts to arrive.
It shows they threw away too much while creating the lite version.
why does it say the Berkeley Humanoid is closed source here? Is it a typo, was this paper peer-reviewed?

The comment criticizes a chart or metric comparing "performance factor" to torque and degrees of freedom (DOFs) in robotics, calling it "the most silly thing" the commenter, a licensed mechanical engineer, has seen. By referencing "Kony 2012"—a widely mocked internet campaign—they emphasize their point about the chart's perceived absurdity. ([The performance factor vs. torque vs. DOFs is the most silly thing as ...](https://news.ycombinator.com/item?id=43801052&utm_source=cha...))
The critique likely stems from the idea that combining performance factor, torque, and DOFs into a single comparison oversimplifies complex engineering concepts. Torque and DOFs are distinct mechanical properties, and "performance factor" is a vague term without a clear definition. Such a chart might misleadingly suggest direct correlations where none exist, leading to confusion or misinterpretation.
In essence, the commenter is expressing frustration over what they see as a technically flawed and potentially misleading representation of robotic performance metrics.
As for the $5K comment — depends where you’re coming from. My kid does VEX V5 and that budget barely covers a full field + comp-ready robots and enough spare parts to actually learn with. And those robots are tiny — one leg of this humanoid is probably bigger than the whole thing.
