Price and availability
from evidence packWhat the Astribot S1 can do
evidence by capability dimensionOfficial product page lists extreme arm speeds: end-effector speed >=10 m/s, acceleration about 100 m/s^2, repeatability +/-0.1 mm, and 5 kg per arm payload. RoboZaps and Interesting Engineering report demonstrations such as wine pouring, vegetable preparation, cooking, calligraphy, laundry folding, shoe organization, and item delivery.
Secondary sources state S1 is designed for full autonomy and uses whole-body imitation learning; RoboZaps says the 'Hello World' demo ran at 1x speed without teleoperation. Astribot's official product page frames S1 as able to learn, think, and work like humans, with VR teleoperation positioned as an AI training data collection tool.
S1 is a wheeled humanoid upper body with a 3-DoF omnidirectional base, 4-DoF torso, 2-DoF head, and 7-DoF arms per secondary reports. Official specs emphasize arm speed and precision but no bipedal walking speed.
Official product page advertises multimodal fusion and comprehensive perception of the real environment. Secondary sources report RGB-D cameras, LiDAR, IMU, force/tactile sensors, and microphone array. The Astribot Suite is reported to use RGB-based visual perception with pre-trained vision encoders.
Astribot official product page says S1 enables safe and intelligent interaction with people. RoboZaps reports integration of large language models for natural language understanding and voice commands.
Official product page lists 4-6 hours endurance with plug-in support. No failure rate, MTBF, uptime, or intervention logs were found.
S1 is human-scale at 170 cm and 80 kg with human-like arm span of 194 cm per official product page. Cable-driven design is described by secondary sources as safer and compliant for human interaction. It has a wheeled base, which suits flat indoor environments.
What is proven
source-backed highlights- Official product page lists end-effector speed >=10 m/s, acceleration about 100 m/s^2, repeatability +/-0.1 mm, 5 kg per arm payload, 4-6 hours runtime.
- BigGo Finance reports 1 billion yuan round, 15 billion yuan valuation, 10,000-unit S and T production capacity, and customers including Golden Horse, ThunderSoft, and JD.com.
- RoboZaps and Interesting Engineering report varied demos and Astribot Suite task success rates of 80-100 percent.
Caveats
read before you trust a demo- No official price or online checkout exists; Astribot sells by quote. Estimates range from about 500,000 yuan to nearly $100,00...
- No independent autonomy audit or intervention logs.
- No official price or purchase path.
- No walking speed, battery capacity, sensor details, or compute specs.
