Methodology

How we research robots

How Robot Buyer Guide sources, dates, grades and re-verifies every robot specification, price and deployment claim — including what each evidence grade means.

Evidence grades

What A to D actually mean

An evidence grade measures the strength of the evidence behind a record, not the quality of the product. A well-built robot with little public proof can still sit at C or D.

  • A

    Strong independent evidence

    Independent testing, regulatory filings, or clearly documented scaled deployment and performance data from unrelated primary sources.

  • B

    Credible deployment or repeated demonstration

    Named customers, paid pilots or repeated demonstrations, each traceable to a dated source.

  • C

    Manufacturer demonstration or claim

    Shown in a controlled demonstration or stated by the manufacturer, with limited deployment proof behind it.

  • D

    Announced, prototype or insufficient evidence

    Announced or prototype-stage, or not yet supported by evidence we can trace. Treated as unproven.

Research workflow

Every record moves through the same stages

A record is never published as complete because it looks complete. It is published when its sources are dated and its conflicts are resolved.

  1. 01

    Discovered

    The platform exists and has an identifiable manufacturer.

  2. 02

    Sources collected

    Primary sources gathered, dated and archived.

  3. 03

    Extracted

    Specifications normalized into common units.

  4. 04

    Cross-checked

    Conflicting figures reconciled against the strongest source.

  5. 05

    Evidence QA

    Every published claim is checked against a dated source before it can reach Gold.

  6. 06

    Published

    Page is complete, cited and eligible for indexing.

  7. 07

    Needs re-verification

    A time-sensitive fact has passed its review date.

Publication tiers

Not every record deserves an index slot

Thin records are kept out of search results deliberately. A page enters the index when it carries researched, cited content.

  • Gold

    Fully researched dossier with cited evidence. Indexed and promoted.

  • Silver

    Verified core facts, partial evidence. Indexed.

  • Bronze

    Structural record awaiting research. Excluded from search indexes and sitemaps until it earns a higher tier.

Time-varying facts

Prices, availability and deployment counts are stored as dated observations against a source, never as a single overwritten field. Each one carries the date it was observed so you can judge how stale it is.

Corrections

Changes to a published record are logged in that page's revision history with the source that triggered them. We correct in public rather than editing silently.

Independence

No sponsored placements, no paid rankings, no vendor approval over editorial content. Manufacturer channels are labelled as manufacturer sources in every ledger.

Machine assistance

Automated and AI tooling assists discovery, source collection, extraction, normalization and drafting. Before a record reaches Gold, every source-backed claim must pass the documented evidence QA workflow above. We do not claim that each record has been manually rewritten or hands-on reviewed.

Hands-on review

A record is labelled Hands-on Review only when Robot Buyer Guide has actually tested the product itself. Everything else is a product profile or an evidence dossier built from cited third-party and manufacturer sources — we never imply we physically tested a platform we have not.
