HUMANOIDLEDGER
方法論——数字を引用する前にまず読んでください。方法論そのものが信頼の資産です。以下はルールであり、要約ではありません。

Methodology

How the Humanoid Ledger is built, what each number measures, and what it cannot tell you. Last updated 2026-11-08.

1. このサイトとは

ヒューマノイドロボットの公開データ台帳です。検証済みの仕様、発表年表、公式動画、そしてウェブ全体から集めた分析済みの報道——さらにそれらから作られた三つの台帳（主張 vs 実測、スコア、問題）が入っています。台帳は独立したもので、掲載するいかなるメーカーとも関係がありません。記帳の決まりは単純です。出典があるものだけを記し、未検証のものは数字を推測するのではなく「未公表」と書きます。

2. Seed data — verified before entry

The 12 models, 31 release events and 8 official videos were each checked against a vendor page or a trade-press report before entry (seeded 2026-11-06). Every row carries its source link. Prices are vendor-published only: target prices, estimates and unconfirmed reports live in the notes field, never in the price column. Where a figure is unpublished or unverified, the cell says Not stated rather than a guess.

3. Live coverage — sources and the relevance gate

Hacker News (Algolia API), Google News RSS (with Bing News RSS as fallback when Google rate-limits the Worker egress), tech-blog RSS (The Verge, Engadget, Wired, TechCrunch, IEEE Spectrum, The Robot Report, PCMag, Tom’s Guide, 9to5Google, Road to VR, UploadVR), YouTube search pages, and Reddit via Google News. Ingest runs hourly. An item counts for a model only when its headline names the product — vendor + model where the name alone is ambiguous (e.g. “Apollo” only counts with “Apptronik”, “Digit” only with “Agility”, “Atlas” only with “Boston Dynamics”). Items that fail the gate are counted as skipped, not silently dropped.

4. Per-article analysis

Each article is analyzed once by Workers AI (Llama 3.1 8B, max 2048 tokens, JSON only): a 1–3 paragraph summary plus structured extraction — sentiment index, comparison, usage time, recommendation index, per-aspect scores, verifiable claims, issues, and the author’s verdict. The model is instructed never to invent numbers, quotes, durations or facts not present in the evidence; undeterminable fields are null, never invented.

5. Evidence checking (what survives, what is dropped)

Two hard guards run on every analysis before it is stored. First, a compared product is kept only if its name appears in the evidence text (title + snippet + body excerpt); anything else is dropped as model invention, and the compares-with flag is recomputed from the surviving list. Second, a verdict quote is kept only if the exact quote appears in the evidence text; otherwise it is stored as null. Aspect scores are restricted to eight aspects — locomotion, dexterity, battery, payload, autonomy, safety, software, price — each scored −100 to +100 only when the article actually discusses that aspect.

6. The scoring decision — what the three retained fields are, and are not

Decision (2026-11-07): the sentiment index (0–100), the recommendation index (0–100) and the author verdict (buy / wait / skip / mixed, with the author’s own words) are retained in full, in the article cards, in the metrics pages and in the three ledgers. They are kept because they measure the source content and its author — the stance of an article, and the conclusion its author reached — not this site’s judgement of any product. This site issues no rating, no ranking, no recommendation and no prediction of its own: there is no site score anywhere on the ledger, no “best model” list, and no verdict written by us. That is the whole of the exception, and it is the only exception: the general rule for this ledger is the same as the no-scores rule — record what happened, cite the source, add no judgement of our own. The three retained fields are presented with their provenance (which article, analyzed from snippet or full text, with what confidence), with nulls counted and never filled in, so a reader can always see how thin the underlying signal is — for example, the recommendation index is not determined in 308 of 329 analyzed articles, because most coverage is news, not a buying recommendation.

7. 三つの台帳

主張 vs 実測は各分析の key_claims を取ります。主張に実測値が付くのは、モデルが実測値を実際に述べた場合だけです（2026-11-08 時点で 289 件の主張のうち 55 件）。残りはメーカーや出典の主張としてそのまま記録されます——列挙するだけで、検証はしません。スコアは sentiment_index と recommendation_index を集計します（分布、件数、平均は非 null の値のみ）および著者の結論の件数。問題は issues[] を同一文言で集計し、モデル別に分けます。台帳にそのモデルの行がない場合は「記録なし」と表示し、決して 0 とは書きません。ライブエンドポイント：/api/ledger/claims-vs-measured、/api/ledger/scores、/api/ledger/issues（いずれも ?model=<key> を受け付けます）。

8. Limitations — read before quoting a number

9. Corrections

Errors are corrected in the open and logged here, not silently fixed.

10. アーカイブ——2026 年 11 月 7 日に追加

Five vendor documents are archived as a baseline (Figure 03 announcement, Unitree G1 product page, Boston Dynamics Atlas product page, Agility Digit solutions page, 1X NEO order page), each with a SHA-256 fingerprint of the raw fetch and of the cleaned text, a 6-character seal and a 64-bit SimHash. The baseline is the first archived version; every later check compares the live document against it and records any change in doc_changes (currently 0 rows — 0 changes means nothing has changed since the baseline, not that nothing is watched). Live endpoint: /api/archive; page: /archive/. The Tesla Optimus official page could not be baselined: tesla.com returns 403 to this fetcher. It will be retried with a rendered fetch; until then it is listed on /archive/ as not baselined, not silently omitted.

11. オープンデータ——2026 年 11 月 7 日に追加

Every dataset behind this site is open JSON with no key. /data/ lists the catalogue with denominators and coverage; /api/open-data returns the same catalogue live, including a row count for every D1 table. Live endpoint: /api/open-data.

12. 第二期の表——永続表、2026 年 11 月 7 日に埋め戻し

Four persistent tables were backfilled from the 330 analyzed articles (snapshot 7 Nov 2026, 20:10 EST) and are served live with a ?model= filter. experience_records (55 rows): every key_claim that carries a measured value, classified by metric (locomotion, dexterity, battery, payload, autonomy, safety, software, price, other) — the value is the number as stated in the article, not an independent lab measurement. review_scores (224 rows): one row per analyzed article that carries a sentiment index, a recommendation index or a verdict — metadata only (reviewer = article source, score / 100, date, URL, aspects tested), no quoted opinion text. failure_modes (93 rows): issues clustered per model by identical wording, with mention counts, first/last seen dates and up to 3 source URLs. resale_snapshots (1 row): the G1, with used_price_median NULL — no used-sold market exists for humanoid robots in any reachable public source (see §13). Live endpoints: /api/experience, /api/review-scores, /api/failure-modes, /api/resale.

13. 歴史——過去・現在・未来の三段がそろい、なお 0 の項目とその理由

台帳は過去・現在・未来の三段をそろえて記録します。現在の 0 を起点にして、未来の変化を待つだけ、ということは決してありません。歴史はベースラインであり、ベースラインがなければ未来の変化に意味はありません。だからこそ、すべての次元を公開情報源と収集済み記事の及ぶ範囲で埋め戻します。2026 年 11 月 7 日の埋め戻し結果（分析済み記事 330 本、2026-11-07 20:10 EST のスナップショット）と検証済みの公開記録は次のとおりです。
