Berkeley Humanoid Lite – Open-source robot

HuggingFace LeRobot. You can build the reference arm easily and cheaply and the software is designed to train AI. There's a lot to explore and extend there and the community is growing rapidly. It's based on the Stanford Aloha project. https://huggingface.co/lerobot

I’d say start with a sumo robot, line follower, or maze solver. That’ll keep you very entertained for a good while.

Micro mouse is a good way to get into robotic.

How does that work for things like taking out the trash, doing dishes, and folding laundry?

Hm, perhaps not - but maybe give the users an option to print such parts, and warn that they may affect longevity of said parts if they do decide to go full manufacturing route.

My potential concern is the "Apple" gatekeeping of parts.

It depends what you're doing. High volume parts, absolutely. It's one of the things that bugs me about the "3D printers printing printers" type projects. 3D printing is terrible for mass producing parts. If you're making 1000+ of something, injection mold it.

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.

As weird as it sounds, but carbon fiber is the most accessible material for making a DIY robot. Anything that uses metal requires expensive machinery. Carbon fiber is labor intensive (i.e. bad for mass manufacturing), but doesn't need much equipment beyond a curing oven for the epoxy (around $2000) for state of the art results.

A 3D printed robot that costs $5000 exerts pressure on the price of mass-produced competitors.

What is interesting is that on their own metric, the Berkley Humanoid is only twice as expensive as the Berkley Humanoid Lite but has more than twice the "performance factor" (0.36 vs 0.14).

It shows they threw away too much while creating the lite version.

The "Berkeley Humanoid" is a distinct robot (they have the "Berkeley Humanoid Lite" named "ours" and colored in orange as the rightmost point on their graph).

Can you explain why to the layman?

I think “Lite” just means it’s a spin-off of the original Berkeley Humanoid — same core team, mostly. Honestly, they’re being pretty modest. “Berkeley Open Humanoid” would also be a good name since it highlights the open-source angle.

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.
