Astribot S1 vs Xiaomi CyberOne V2

Astribot S1 is a China-built wheeled humanoid upper-body robot with official specs of 170 cm, 80 kg, 5 kg per-arm payload, end-effector speed >=10 m/s, acceleration about 100 m/s^2, repeatability +/-0.1 mm, and 4-6 hours runtime. It uses cable-driven arms and is sold B2B by quote, with no public price. BigGo Finance reports a 15 billion yuan valuation, 10,000-unit S and T production capacity, and customers including Golden Horse, ThunderSoft, JD.com, and Robot MART stores across six Chinese cities. Secondary reviews describe cooking, food prep, cleaning, calligraphy, and other demos, and report Astribot Suite task success rates of 80-100 percent. Autonomy is claimed but not independently audited, S1 has no bipedal walking speed, and no S1-specific deployment output metrics are published

Xiaomi CyberOne V2 is the second-generation of Xiaomi's biped humanoid, described as roughly 1.70 m tall and shown publicly at Xiaomi's April 2026 Investor Day, at the World Robot Conference in August 2026 and at IFA Berlin in September 2026. Its only quantified capability evidence is a company-reported self-tapping nut-installation task on Xiaomi's own Beijing EV assembly line: 90.2% success over a three-hour autonomous run inside a 76-second cycle, rising to about 98% after roughly four months of on-site application. Xiaomi also reports a redesigned hand at human scale with degrees of freedom in the 22–27 range, full-palm touch, 150,000-cycle durability and evaporative cooling, and has open-sourced a 4.7-billion-parameter VLA model. Nothing here is independently verified: there is no Xiaomi spec sheet, no price, no external customer, and the six videos in the source set are title-only
