Astribot S1 vs EngineAI T800

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

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
