This reminds me of the Otto DIY (https://www.ottodiy.com/), which also used to be a free Arduino (nano) based, 3D-printable robot until it was bought by HP. Just like with the JBR-001 it seems that the main goal has shifted towards making it a commercial product, which is a shame. Especially the low price point made it so attractive for beginners and students alike.
Does anyone know of similar, really open source and free projects like this?
Thanks for sharing! Love that it's open source with the 3D files and instructions included. My son and I are going to build this together. Great project.
Thats great to hear! Building it together with your son is exactly the kind of thing we hoped JBR-001 would inspire. Have fun and let us know how it goes!
I have started to use my editor to build a robotic arm and we are using JEPA for perception and Ornith local model for reasoning as a hybrid approach for arm because there’s no single model that handles both.
I’m sad that it uses the Uno Q. I really dislike the uno Q, since it uses QC SoC, which means no cheap Chinese clone, which is not very accessible to everyone.
Chinese clones of Arduinos are normally between 3x-6x cheaper, and if your project uses dozens or hundreds or thousands of them, especially in developing countries, that's a major price delta.
I assume at those scales it quickly becomes economical to design a custom board instead of using modules that are probably seated on cheap custom PCBs anyways.
If you have a bit of time to learn the skills, it’s economical to design a custom board even for 5-10 units. An integrated controller module like an ESP32 can basically just be plonked onto a board with a voltage regulator and used like an Arduino.

Which does not sound much, but to someone living in less developed country, that matters a lot
