Each pillar is scored 0–100 from published specs, then weighted into the HMX. Compare it only with other humanoid robots — each category uses its own reference scales. See the full methodology →
Notable
The manufacturer specifies 15 kg handling across a 0–1.8 m workspace and autonomous battery exchange within three minutes. Continuous availability relies on battery-swap infrastructure, rather than 24 hours from one charge.
Deployment evidence
Legacy mentions are unverified. A partnership or announcement is not proof of an active deployment. Evidence labels do not change HMX v2 scoring.
