EngineAI T800 vs Xiaomi CyberOne V2

EngineAI T800 is a full-size bipedal humanoid (1.73 m, 75 kg official) with 29 body DoF excluding dexterous hand, 450 N·m peak joint torque, and a claimed 4-5 hour solid-state battery runtime. It launched on 2025-12-02 from 180,000 yuan with four versions and was demonstrated at CES 2026. In May 2026, EngineAI announced mass production with first batch delivery and a 10,000-unit scalable capability. However, all strong evidence is company-reported. No named customer deployment, autonomous task execution, or independent verification was found. addoobot lists conflicting specs (84.5 kg, 2 h runtime, 1.22 kWh ternary battery) that lower confidence in endurance

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
