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
Japan's flagship 'domestically-made' humanoid prototype, built by a 14-company/2-university consortium; its public debut walk failed due to a leg malfunction.
