Company Claim
Astribot states S1 is commercially available in China and positions it for household chores, food preparation, and lab automation; the company launched a lower-cost sibling product, T1, in May 2026 to broaden real-world adoption
What's Actually Confirmed
No named customer, pilot site, or unit-count deployment claim was found for S1. Claims of international availability across nine countries (US, Germany, Japan, South Korea, UK, Canada, France, Australia, India) appear only on a reseller/advisory site (RoboZaps) and are not corroborated by Astribot's own materials or tier-1 press — excluded from this record's confirmed claims
Frequently Asked Questions
What is the S1 and who makes it?
S1 is a full-size wheeled humanoid with cable-driven arms reaching 10 m/s, built for whole-body imitation learning and autonomous task execution. It is manufactured by Astribot and was announced in 2024.
How tall is the S1?
S1 is 1.7 m / 5' 7'' tall.
How much does the S1 weigh?
S1 weighs 80 kg / 176.4 lb.
How much can the S1 carry?
S1 can carry a payload of 5 kg.
How much does the S1 cost? Is the S1 available to buy?
Astribot has not published a price for the S1 — it is quoted on enquiry. No public pricing confirmed by Astribot for S1. Early commercial units available in China from late 2025. A lower-cost sibling product, T1, launched May 2026 from approximately $13,000 (confirmed via Interesting Engineering), but this is a distinct, smaller product — not S1's price.
What are the main strengths of the S1?
- 10 m/s arm speed and ±0.1 mm repeatability — highest documented arm performance of any humanoid-form robot
- 23 DoF cable-driven design provides compliant motion and safer human interaction than rigid-link alternatives
- DuoCore-WB imitation learning with 80% average task success rate across 6 benchmarks, per peer-reviewed arXiv paper
- Full sensor suite — RGB-D, LiDAR, IMU, force and tactile sensors confirmed
- Company has since shipped a lower-cost sibling product (T1) with a confirmed price, suggesting real manufacturing capability behind the platform
What are the limitations of the S1?
- Wheeled base limits deployment to flat indoor environments
- No dexterous hands — end-effectors not specified on primary sources
- No public pricing confirmed for S1 itself — third-party estimates conflict by up to 3x
- Compute specifications not published
- International availability unconfirmed beyond unverified reseller claims
- No named commercial or pilot customer found anywhere
