Full-Stack In-House Development

Developing the robot body, its core components, control, and the large model all in-house rather than buying them in.

This means a robotics company handles nearly every major layer itself — mechanical structure, joint modules, dexterous hands, electronics, motion control, perception, and the upper-level large model — rather than buying someone else's robot body or calling on someone else's model. The upside is that hardware and software can be iterated together, problems are easier to trace, data formats stay consistent, and long-term costs are more controllable; the downside is that it takes heavy investment and a long timeline, and the team has to be capable across the board. The contrasting models are a body maker that builds only hardware, a brain company that builds only models, and an approach that buys in core components and integrates them. The phrase “full-stack in-house” gets used loosely in marketing, so it's worth checking whether the key components and models really were built in-house.

ExampleRobotEra's website describes itself as “fully self-developed across hardware and software,” building the humanoid robot L7, the dexterous hand XHAND1, and the end-to-end model ERA-42 all at once.
