Astribot S1 vs ergoCub

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

ergoCub is IIT and INAIL's research humanoid, standing 150 cm tall, weighing 55.7 kg, and designed to reduce physical strain on workers in industrial and hospital settings. Its strongest evidence is a peer-reviewed Nature Machine Intelligence figure showing collaborative payload lifting with a human and live walking on stage. Official IIT sources confirm the 2023 debut and ergonomic purpose, while secondary dossiers report about 10 kg load-bearing, NVIDIA Jetson AGX Xavier plus Intel i7 onboard compute, depth/LiDAR sensing, and research claims such as up to 43% energy reduction and DNN-driven locomotion. However, no battery, runtime, walking speed, total DoF, hand DoF, price, or customer deployment exists in the reviewed evidence; autonomy is mostly simulation-only or title-only
