Build it

No public build path.

No ORP build package yet.

That means no BOM with prices, no fabrication list and no step graph in the registry. Build from the upstream material, or write the package: a robot.toml plus BOM and steps.

Upstream

Simulate

Load it in the browser simulator and train a policy before building.

Z-Bot (Zeroth Bot) →K-Scale Labs · humanoid · index 8.4

No buildable class sits between quadrupeds and humanoids yet, so the next rung is the easiest humanoid.

NoteRuntime 1-2 h on the 8,000 mAh standard battery; EDU 15,000 mAh ~2-4 h. Included as a closed reference point.
