  "notes": [
    "Capabilities research (2026-09-20): UBTech's own footage and press coverage document Walker S2 performing an autonomous, dual-arm hot-swap of its own back-mounted battery in roughly three minutes (e.g. therobotreport/CNET/Thomasnet coverage of the demo video) -- a real capability, but there is no matching id in this site's fixed capabilities list (closest is 'continuous-operation-1h', which requires one continuous run, not a swap event). Aggregator pages (HumanoidHub, robotsxhumanity, etc.) describe box lifting/sorting and warehouse deployment in generic marketing language without a specific dated video or independent observation with a literal, checkable quote, so no box-handling capability entry was added. Capabilities block left empty pending a source that ties a named id to a quotable, dated demonstration.",
    "UBTech's own product page (ubtrobot.com/en/humanoid/products/walker-s2) is reachable and confirms payload and battery-swap claims directly, but does not state height or weight. Height (1.76 m) and DOF (52) here are sourced from a secondary aggregator (heyupnow.com) that republishes UBTech's launch claims without linking an original press release; no PR Newswire/Business Wire/IEEE Spectrum/Robot Report coverage with those exact figures was found during this session. Treat height/DOF as needing a stronger source in a follow-up.",
    "Weight could not be confirmed from any source checked; third-party aggregators disagree (43-77 kg depending on battery configuration), so it is omitted rather than guessed.",
    "The November 2025 mass-production/delivery announcement is UBTech's own press release (claimed-level evidence per schema); it names deployment partners but the fetched text contains no photo, serial number, or independent verification of a specific customer's unit, so delivery.status stays 'claimed' rather than 'shipped'.",
    "Shipped-bar re-check (2026-09-20), applying this site's actual rule (named customer + image via the customer's own or an independent channel; invoice/serial/unboxing/customs are alternatives, not an added requirement, so the earlier note requiring both was too strict and is superseded by this one): UBTech's own PR Newswire release (Nov 2025) names BYD, Foxconn, Geely, Zeekr, Audi-FAW etc. only as order sources/collaborators, with no photo tied to a specific customer's unit. The one strong independent-channel match found -- SCMP's photographed, on-the-record coverage of a Zeekr Ningbo deployment (published 2025-03-03, https://www.scmp.com/tech/tech-trends/article/3300872/) -- explicitly names the model as 'Walker S1', not Walker S2 (Walker S2 was announced later, 2025-07-23), so it is evidence for a different generation and does not carry this record to shipped. No named customer with photographic evidence of a specific Walker S2 unit (as opposed to S1/S Lite) was found via customer or independent channels. Remains claimed, not shipped.",
    "locomotion left out (2026-09-21): searched the manufacturer's own product/press page and its main launch coverage (The Robot Report / IEEE Spectrum / named outlet where applicable) for a literal quote naming the propulsion (\"bipedal\", \"legs\", \"walks\", \"wheeled base\", etc.); none of the pages fetched in this pass contained a checkable sentence naming it specifically for Walker S2 -- most pages describe height/DOF/speed without ever stating the locomotion type in words. Left out rather than inferred from photos or category. Revisit with a source that states it directly."
