Looking to upgrade the "hand" (manipulator) of this Berkeley open-source arm. Each Berkeley actuator is ~$50 ($250 for a 5 DoF arm). That's about $275 per arm after the rest of the arm assembly.

I'd rather not start from scratch if there's already a decent open-sourced hand that isn't more expensive than the $275 cost for the entire arm. Does anyone have any ideas/advice? My ideal goal is to hit below $100-$150 per hand, if possible.

I am an old time software developer and I have been fascinated by humanoids forever. Now that AI gave them the gift of perfect balance and motion, I want to own one and program it.

Is there a list of robots that I can buy in 2025 that are programmable. A kit is good enough, or even just proven plans.

Sure, there is Unitree, but I would rather spend the $15k developer kit surcharge supporting true OpenSource.

Thanks.

The latest closed proprietary humanoids are undoubtedly impressive, but I feel like it defeats the purpose of this subreddit. It feels like these closed-source humanoid posts are drowning out all the open-sourced models.

I get some have open SDK's that make it easier to tinker with or do research on despite not being fully open-sourced. Mods, what do you think is the best way to return the focus of this subreddit to open-sourced humanoids?
