K-Scale K-Bot

K-Bot is an open-source humanoid robot from K-Scale Labs aimed at making capable humanoids accessible. It is built from COTS components on a 48V CAN-bus actuator architecture with a modular, repairable design: hands swap via a lens-mount interface, the head detaches, and the whole robot presents largely as a single USB device. The repository publishes the mechanical CAD (Onshape), electrical design docs, and a software stack split across submodules for the operating system (kos-kbot), simulation (ksim-kbot), and inference (kbot-inference). The project is in public alpha and is also sold as a developer kit.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A primary assembly 3D asset is available from kbot-v2/robot.mjcf.
• Source-backed bill-of-materials evidence is linked with per-part provenance where available. Prices marked estimated are not yet verified against a vendor.
• A transparent reproducibility score so buildability is a sortable, first-class property.
• Cross-links to the source repo, datasets, models, and forks.
