How we work
This page describes the rules our content follows. We publish it because a specialist platform should be judged by its method, not by its self-image.
Sources
Primary source before secondary source. On legal questions we cite the legal text, not a law firm's summary of it. On technical information we cite the manufacturer's documentation, not a dealer's product page.
Every source with its date of retrieval. Every specialist article ends with a list of sources giving title, publisher, reference and the date on which we last consulted it.
Legal acts via permalinks. We link regulations and directives through the European Union's permanent identifiers, not through search results.
Standards only with title and scope. The wording of standards sold for a fee is protected by copyright, and we do not reproduce it. We state which standard applies – you will need to obtain the full text yourself.
Market figures only with their basis. Published estimates of the market volume for mobile robotics vary by several multiples for the same period. Where we cannot follow the methodology, we do not repeat the figure. A sound analysis does not need an unsupported figure in the billions.
State of the law and maintenance
Every article with a legal dimension states the applicable legal cut-off date. The law changes; an article without this information is worthless, because nobody can tell what it is based on.
In addition, every article has a review interval. For topics with a short half-life – the Machinery Regulation, the AI Act – it is three months; for stable fundamentals, twelve.
Where an article has been changed in substance, this is recorded in the change log at the end of the text: date, type of change, reason. Even when it is a correction. Especially then.
Expert review
We have articles with legal or safety-related content reviewed by experts. Where this has happened, we name the reviewer with their qualification, the date of the review and its scope.
Where it has not happened, nothing is stated – we do not set a review date that reflects no review.
This also applies to seemingly harmless fields: an article shows “Last checked” only once someone has actually checked it.
Limits of use first
Every article states its limits of use before it describes the possibilities: what a system cannot do, where it may not be used, what an article does not cover.
This is not a precaution but the order in which a procurement decision is actually made. Anyone who learns only at the end that an area of their plant is excluded has read in vain.
The robot database
Additional rules apply to information on individual models.
We describe the state of documentation, not the product. For every piece of evidence of conformity we distinguish four states:
- documented – evidence is publicly available, with source and date of check
- no public information – we searched on the date stated and found nothing
- not applicable – the requirement does not apply to this product, with reasons
- to be added – not yet researched
The difference between the last two matters to us: where we have not searched, we do not claim to have found nothing.
No estimated values. Where information is missing, we say so explicitly. We mark manufacturer specifications as such and give the test condition wherever it is stated.
No third-party conformity assessment. We do not determine whether a third-party product meets the requirements. Only the manufacturer's documents and the competent authorities can do that.
Conflict of interest
roboterum.de is operated by etree GmbH. etree GmbH is seeking a distribution partnership in the field of inspection robotics.
We disclose this conflict of interest – in the footer of every page and additionally on every page of the robot database. It changes nothing about the rules above, but you should be aware of it when you use our information.
We document models from all manufacturers by the same criteria, including those with whom we have no business relationship – and including those with whom we are seeking one.
Tools
Our articles are created with the help of digital tools, including AI-supported systems for research and writing.
Responsibility for the content always lies with the named author. Every article is read, checked and signed off before publication. An article without a named responsible person is not published.
Corrections
We make mistakes. If you find one, please write to us.
We mark corrections of substance in the change log of the article concerned. We do not silently remove incorrect statements – a documented correction is more credible than a flawless text.
This applies in particular to information in the robot database: we welcome notes from manufacturers on their own models and incorporate them with the source stated.
What we do not publish
- purchase prices, margins and pricing logic
- manufacturers' internal ratings and comments
- names of reference customers without written approval
- manufacturers' manuals without the rights holder's approval
- statements on the conformity of individual third-party products
