Specs
57 of 195 measures disclosure, not the robot: it counts the specs the maker and the directories we read had published when this page was last checked, so a robot with fewer published specs is not a worse robot. Makers also measure differently — height with or without the head, payload rated or peak — so two sources can both be right and still disagree, which is why every value carries a chip naming who stated it.

No value below has been independently measured or filed with a regulator — every number is a claim by the maker or by a third-party directory, and the chip on each one says which.

A value below no longer shows on the page — it was superseded, or withdrawn after review. Kept here, not deleted, with the reason it was withdrawn.
- Arm span: 1,940 mm2026-09-29
[statement 6abb9017a19ebf81367f5d6f] a bare "Width - 1940 mm" cell states a width, not a fingertip-to-fingertip span; the value survives on four other statements including the VENDOR's own "Arm span 194cm" — read with its page context on 2026-09-29. Quote: "Width - 1940 mm"
- Runtime: 6 min2026-09-29
[statement 6abb9017cce4384fdd5d030b] "Max Op. time 6 mins" is this directory's template printing an HOURS figure in a minutes field — the maker states "Endurance 4~6hours" and eight other statements agree, so 6 minutes is a unit artifact, the class CLAUDE.md records for the wheeled-robot "3 km/h" template row — read with its page context on 2026-09-29. Quote: "Max Op. time 6 mins"
- Degrees of freedom: 142026-09-29
[statement 6abb901765de5dbd69dabbb5] the quote says "derived" — the directory computed it rather than the maker stating it — review-flagged on the astribot-s1 dry run, then judged by hand as a class. Quote: "Degrees of freedom: 14 (2 × 7-DoF arms, derived)"
- Teleoperation interfaces: VR2026-09-29
[statement 6abb9017a5220a288c34b117] "VR-based training ... to learn tasks from human demonstrations" is a TRAINING method, not a teleoperation interface — review-flagged on the astribot-s1 dry run, then judged by hand as a class. Quote: "VR-based training allows it to learn tasks from human demonstrations"
- IP rating: low IP rating2026-09-29
[statement 6abb90171a081d2d8dcf28b4] the value is the prose "low IP rating", not an IP code — there is no ingress rating here to publish — review-flagged on the astribot-s1 dry run, then judged by hand as a class. Quote: "likely low IP rating, indoor use only"

- Locomotion: Stationary2026-09-29
[statement 6abb9017ea570f394c8589cd] an either/or sentence cannot prove STATIONARY when every other source, including the maker, states a wheeled base — review-flagged on the astribot-s1 dry run, then judged by hand as a class. Quote: "stationary or wheeled-base humanoid torso robot"

[statement 6abb9017be53876f218b4947] derived from a price the same quote calls "Indicative" or a "Legacy record price" — neither is a current list price — review-flagged on the astribot-s1 dry run, then judged by hand as a class. Quote: "Price $70,000 Legacy record price · Jul 17, 2026"
